Nina dithering. Confused about how that happens.
Nina dithering I'm Page 1 of 2 - how to settle effectively after dithering - posted in Experienced Deep Sky Imaging: Hi guys, I have been trying to adjust my dithering settings so that I settle after dithering effectively before resuming the next exposure, but I just cant come up with the right combo that will allow me to do that. My sequence uses smart exposure with dithering which appears to work after doing this. According to Cloudy Nights there is an undocumented facility for this in NINA - using the Direct Mount Guider instead of PHD2. Changed dithering from random to spiral Changed RA algorithm to the default Hysteresis from PPEC. Be it for beginners or for advanced astrophotographers, N. Clarky2 Advanced Sequencing Sequence Templates#. Dithering with Starsense Autoguider - posted in Celestron Computerized Telescopes: Hi everyone, I recently purchased the star sense autoguider for my C8 Edge HD and I normally use NINA as acquisition software. Confused about how that happens. When using an intervalometer I typically allow 15 seconds between shots to give the sensor I can get a link between Metaguide and NINA but I can't get Metaguide to respond to the Synchronized Dither command sent by NINA Dithering does not work between Metagiide and NINA . Are you planning to support dithering via CPWI for the Celestron StarSense Autoguider? Some applications, such as NINA appear to be going that way. I have been guiding with PHD2 but triggering my Sony with an intervalometer and using manual dither tab in PHD2. When guiding is already started, no action will be taken. Star Adventurer GTi Dithering - posted in Beginning Deep Sky Imaging: Hello Like the title says, I want to know if its possible to dither on this mount that I got a couple a days ago. It does so much so well, and keeps everything in one convenient app. g. I don't use Nina, so I can't help with that, but if theres options try some spiral dithering. I recently purchased a second SW Esprit 100ED to speed up my data acquisition. Viking 1. It was developed by a group of amateur astronomers with the goal of creating a comprehensive and user-friendly software package that could be used for all aspects of astrophotography, The only issue I have is that my guiding goes wrong when I attempt to dither. Hope that helps - I’ve heard plenty of people say that RA only dithering works well, the only way to know if it’s going to work for you is to try it. Dithering is an important part of the modern image acquisition process. Some simple questions about guiding/dithering. Offline Sky Map Cache (3. So my plan was to calibrate my celestron mount, run a phd2 calibration, slew to my target and then boot the nina software and begin my sequence of images and dithering with Nina ? Just trying I see the spike on a dither with my HEQ5 with belt mod. In all that time, I have seen drift only a couple of times, and the root cause always came back to my tracking NINA Flexure correction With Dithering - posted in Experienced Deep Sky Imaging: Anyone care to weigh in on the proper settings for using dithering and flexure correction in NINA. The primary controls the mount, guiding and dithers. Thank you. Hopefully you understand the proper way to derive dither settings and put them into NINA, otherwise you are going to have a difficult time. What shoul NINA developer Stanley Dimant has produced a video which details and explains the many new features and refinements which will debut with the upcoming 1. I have a ZWO 120mm Mini w/ WO 32mm Uniguider scope, and I cannot get them to work with NINA either. Lets say I want to run a widefield camera using a piggyback mount on my telescope. But in preparing to get my first monochrome/dedicated camera this winter I was learning that my Dithering causes a mount to make tiny random movements of only a few pixels, allowing stacking software to compensate for hot and cold pixels in final stacki Dither Settle Pixel Tolerance and Settle Time: these are important parameters that define the successful end of a dither move. I. 5 pixels and the settle tolerance set to 2 pixels. Restore Guiding# This trigger will start guiding each time after an instruction inside its context. I dont have an issue since my guide results have been very good but as I read these articles, I dont see where I can makde adjustments to settling time while dithering in PHD2. NINA synchronized dither value - posted in Experienced Deep Sky Imaging: Hi forks! Ive just set up 2 telescopes side by side on a mount. It has to have a guide star locked in order to know how far to move the scope to dither. In this video I go through how I am running the two scopes with two instances of NINA and show ho Dithering with a DSLR and Star Tracker . I saw a lot of links a few years ago asking if there’s dither software to drive the mount . Distribution permission granted by the Space Telescope Science Institute. You will need to set the dither parameters somehow. I have read there are areas in SGP or Dithering With TSX - posted in Beginning Deep Sky Imaging: Hi All, I have been setting up a new rig more suited for astrophotography and am trying to settle on software packages that can handle the data acquisition so that I can marry the hardware and software together with todays advancements. Thanks, Peter Increase the settle amount in NINA. I run a dual rig with an OAG on the master scope, and I operate the slave camera and focuser on a second instance of NINA. With the Mach2, I dither every images for longer sub exposures (3 - 10 min) and less frequent for shorter ones. to communicate with PHD2 and command operations such as dithering and for receiving guiding telemetry, PHD2's internal server must be enabled. Can set tracking – allows NINA to start/stop tracking; Mount can be parked – Allows NINA to send parking command in the post imaging sequence; Slew start delay – is checked by default mostly because of cameras, I’m just leaving it default. cs|ShouldTrigger|261|Meridian Flip - There is still time remaining - max remaining time 00:15:07, next instruction time 120, next instruction Category: Camera, Item: TakeExposure, ExposureTime 120, Gain 100, Offset 250, ImageType Here is one of the dither events zoomed in and with corrections enabled Next time I get a chance to try I will push the settle time much further and see if that helps. Right now I am playing around with taking wide field shots Paramount ME, Sky X and NINA / Dithering - posted in Beginning Deep Sky Imaging: Hello, I have a ME, run Sky X and NINA. Previously the auto update was always just looking for released versions. Back to top #11 Chaser of Photons Chaser of Photons. 24 arcsec/pixel on imaging system) just shy of the imaging system resolution to produce round stars. I love Metaguide and it will be a pleasure to see it working fully with NINA . Yes, I get the niggling timout message as well. 5px. NINA sometimes doesn't wait for slewing to finish. 07/pix - My guiding scale is 2. I guide using Sky X, NINA for camera, QHY 533C, control and Sky X for mount control and guiding. So I checked my settings and the settle pixel tolerance was 1. Paulo Gordinho. It was developed by a group of amateur astronomers with the goal of creating a comprehensive and user-friendly software package that could be used for all aspects of astrophotography, Center After Drift in NINA plate solve fails - posted in Beginning Deep Sky Imaging: Hi all, I love NINA and, with all the things that can go wrong, I only have one issue. will keep configuration requirements to the minimum and will assist you through the process of imaging. APT: meridan flips & unguided dithering - posted in Astronomy Software & Computers: Hi all, Im pretty much of a newbie here, so I hope Im posting where I should Im an APT user who recently learned about NINA. Dither in RA only? - posted in Experienced Deep Sky Imaging: Is it sufficient to dither in RA only? Ive been having a problem with dec taking a long time to settle after a dither, probably due to the mounts large dec backlash or related peculiarities. We cover image scale and dither scale along with som All you need to do in NINA is to tell it in the guiding tab how many pixels you like to dither and how often. The time dithering worked it didn't take long till it said dithering finished(i think within 60s). Instanzen Astrophotography dithering techniques will help you to achieve sharper noise-free images. It didn't give me any errors and yet I cannot see any dithering when checking through all the frames, only drift. 46 arcsec/ pixel) that translates to a value ( 1. How do you perform coordinated dithering in NINA without NINA - phd2 dither settling tolerance - posted in Beginning Deep Sky Imaging: Hi guys, I am trying to tighten my imaging settings and determining the dither settling tolerance in NINA is something that I am having a hard time wrapping my head around. I use an svbony 60mm ($80), asi290mm mini ($330). Nina is talking to the camera It can. If so, it makes a very simple compact system possible (e. N. Short focal length (500mm) so I asked for 5 pixel dither. It only stopped for maybe a second, or less. Could you consider implementing There are many of us that would, even if we’ve not expressed it out loud, just given up on ASIair and used NINA sync dither instead. so I have setup sequence in NINA to dither every 2 subs , but the sequence runs each filter twice first and dithers after, so it saves a bit of time. So here it is: 1. Plate Solving: Use one of several plate-solving software packages to plate-solve images for accurate weird fixed noise pattern after dithering - posted in Beginning Deep Sky Imaging: Hi all, I went out last night and decided to get some very quick integration time on M33. - posted in Beginning Deep Sky Imaging: I just noticed that it seemed like NINA wasnt stopping for very long during a sequence, when dithering, and it made me a little bit suspicious. will wait after triggering a dither to resume imaging. If the dither setting is N, a dither will be added before the N+1 th occurrence of a filter. CEM60EC mount, PHD2 guiding, NINA control and acquisition. Présentation, utilis Then at the advice of bendgrampie above, I read through the NINA Dithering section in the NINA manual. However when I try it the primary scope dithers without waiting for the secondary scope to finish a subframe. I will be visiting my sister and wanted to do some imaging, but my choices are an Alt-Az Nexstar mount or a SkyGuider In NINA with a Dither Pixels of 1 or maybe 2px the DEC backlash / Dithering is somewhat controlled. Using 4 sec exposures on PHD2 so allowed 30 sec settle time. For more information about dithering, visit the dedicated page about it. Veremos en qué consiste conceptual Misc. Learn How to Reduce Pixelation and Improve Image Quality. 1) Start Nina, connect camera, filter wheel, focuser, scope and guiding. Right now I am probably throwing away close to 30% of frames due to this issue so I really have to sort it out. However, DS is designed for the more advanced user who is looking for more control over their sequencer. However, dithering during a sequence caused problems. A. I have NINA configured to dither after each image. Basic setup: NINA, Mach2, Dec Arc Model, Direct Guider, Dither every frameAssuming NINA isn't dithering in an exposure, what type of telescope are you using? Is it possible something in the optical train shifted?-Ray You just configure NINA to do dithering via phd2 and specify the dither amount and settling tolerance (I'm not sure what good settings are and they would require some experimentation) and activate guiding in the ssag - then begin the imaging sequence in NINA, including dithering. This topic has come up a few times before but either Ive misunderstood the answers or just cant get it to work. 3GB) – a cache of images to be able to display images of the complete sky during offline framing. First, I’ve Page 1 of 2 - dithering randomly breaks guiding - no idea why - posted in Beginning Deep Sky Imaging: Hello! I did read a few other threads, found no solutions, so there it is: Mount is iOptron 40CEM with an iGuider Scope is 800mm f4 newt, with coma corrector and a DSLR (Canon 250d / SL3) on top. (Nighttime Imaging ‘N’ Astronomy) is a free and open-source software program for astrophotography and astronomy data acquisition running on Microsoft Windows. You are effectively running two captures but will need to synchronize the two instances so the dither doesn't ruin the secondary camera. Since I don’t have guiding, my target often drifts and even though I either every frame, I end up with walking noise. And for the slave, other than the camera, do I dithering in nina? - posted in Beginning Deep Sky Imaging: Hi all been doing this for a while and never used dithering(doh) using nina and phd2 ,where is dithering set nina/phd2 or both and any recommended settings/equations thanks SkyGuider Pro - Dithering, PHD2, and NINA - posted in Beginning Deep Sky Imaging: Lots of SkyGuider Pro questions lately, so I thought I might add my own Actually, I did not see an answer to my question exactly, so want to get clarification. Ask questions, share your photos, make suggestions, and help other users. Although it is not necessary to use a Paramount mount with TheSkyX, we will cover the setup generically Controlling the Benro Polaris with NINA is an absolute game-changer. I usually dither by something like 5 pixels. When setting up a sequence, I cant seem to find a setting for delay between exposures. Would dithering in RA only turn hot pixels [correction; my fumble; I meant fixed pattern noise] into short lines or dotted lines? I think with the advanced sequencer in NINA you could probably just setup a wait time and send a dithering command every 10 minutes or so. I changed my dither movement to 7, my settle pixel tolerance to 1. I have the dither set for 5. I'm not sure if NINA also can turn guiding on/off in the ssag. Page 58 of 64 - First time trying out N. 48/pix I currently have my phd2 pixel dither in NINA set to 5 Dithering Problem with NINA & PHD2 - posted in Beginning Deep Sky Imaging: Hi, I am a beginner and I just finished my first session of imaging M31, I use NINA and PHD2 for guiding. Guider Pixel Scale: 4. This you can even see in the PHD2 graph. 98 arcsec/px I am thinking that PHD2 is not connected to the system somehow. A Configure Com Ports in Windows Install ASTAP Install Star Catalog Install NINA Configure NINA Configure EQAscom Configure EQMOD Allow Site writes Set up Pulse Guiding (should be Guiding and Dithering - posted in Beginning Deep Sky Imaging: Hi Folks. CMOS and CCD sensors suffer from various types of electronic noise, such as fixed-pattern noise, and defects such hot and cold pixe Start off with a small scale dither and make sure PHD can recover within the allotted settle time. N. No crashes. 2022-08-31T03:59:47. No polar-alignment, no worries!The driver: https://github. Known limitations: Dithering will happen every possible synchronized frame and is not changeable; Auto-Update Channels. Im bothered by the APT automated meridian flips. Astromart. If dithering is performed every 2 exposures, what is the ideal number for the After Exposures tab. Im using NINA for acquisition and PHD2 for guiding. 0260|INFO|MeridianFlipTrigger. I tried all sorts of numbers and just after 5 seconds it says Settle timeout while my settle time out can by literally any number. 8 release. I run a three scope array on the mount. Hopefully future is soon - it’s not complicated to implement. 10 Micron 1000HPS, NINA. 11). Welcome to my channel dedicated to start your journey into Astrophotography as well as reviews of equipment and software Jeffery Richards: Jerry, I didn't think NINA had it's own guider functionality. 45"/px (guiding), ie. Anyone else having success with this functionality? You use the Direct Guider device in NINA instead of PHD2. When PHD performs a dither, it doesn't move the mount instantly. I’m trying to learn about NINA capabilities for my rig mainly to introduce dithering and better slewing/plate solving. I autoguider with dithering on my star adventurer. 5 arcsec In setting the NINA dither settle pixel tolerance - Am I correct in setting this to a guider pixel value (0. Nina and phd2 sequence - posted in Beginning Deep Sky Imaging: Beginner question: I have been guiding with PHD2 but am going to start using NINA to run the camera. En esta tercera entrega de los tutoriales de NINA, repasamos la técnica de Dithering para mejorar la relación señal/ruido. When creating a new sequence item via Framing or when just adding a new target from anywhere in the application the default values of a Sequence will most likely not be satisfactory for a user. Vediamo co Hi all,im starting astrophotography,and i was wondering if i should dither if i don’t have a autoguider. Acquisition software is NINA, connecting to things via ASCOM. I've posted this query on the Discord NINA forum but maybe the folks on SGL can help me out. You'll likely need to tune this based on how your mount We would only need to dither when each set of LRGB is passed. The existing NINA Synchronization plugin provides support for multiple OTAs/cameras on a single mount with a single guider. rotate events to minimize dither. 2 Telescopes, 1 Computer & NINA - posted in Experienced Deep Sky Imaging: Hi, Im seeking some help with a dual SkyWatcher Esprit 100ED setup. Link to comment The dither commands look like they should be coming from NINA, and the NINA docs indicate you should enable dither in the sequence. I have never tried running a side by side rig before so its all new to me. 1 guider pixel = 0. To NINA Dithering Introducing Really Bad Walking Noise - posted in Beginning Deep Sky Imaging: I love NINA. One notable observation was my guide star SNR was very low , only 12 to 15 Multiple Cameras and NINA - posted in Beginning Deep Sky Imaging: I know Ive seen this somewhere before, but I thought Id ask here. Last night I ran into a guiding issue with NINA (using all the latest software, i. 1 Find target in Stellarium and import in to NINA framing assistant 2 Set up the framing and Mosaic as required 3 Click on 'Replace as sequence' button 4 Go to sequence tab and set up exposures, dithering, tracking etc 5 Hit the go button! Works like a charm. Look for the synchronized dither plugin for nina. I have the dither set up in NINA and after it performs the dither, either the RA or DEC or both starts climbing away from zero as if they get stuck. I saw many people moving 15-30px in the main camera but I think mine is just fine to fix de fixed pattern noise of the ASI183, which is quite low. This differs from PHD2 which tells N. Even though you aren't using PHD2 to guide - CPWI should catch the dither commands and cause the SSAG to dither. RA and DEC were not orthogonal. when guiding has settled after dithering. No physical guider. - posted in Beginning Deep Sky Imaging: So I see this quite a lot with NINA, mostly when using the Framing Assistant, where NINA will immediately start trying to plate solve the image before the mount even slews to the target, Ive gotten so used to it now that its expected behaviour, and so I just cancel the first This video really covers in detail what goes into setting up dithering properly in your image sessions. I left mode to random and rise the scale up to 5. I have effectively gone from 3 arc-sec of PE to just about ZERO PE with an inverted PE curve. Dithering takes up quite a bit of imaging time. I currently am using an HEQ5 and a Canon DSLR but don’t have a guide scope or cam. Edited by Paulo Gordinho, 12 May This guide will walk you through the process of using NINA with a Paramount MX+ and TheSkyX to control the mount. This is with NINA and PHD2 on my mini-pc, but I'd guess that the SA and ASI Air would take a similar amount of time? same direction/axis. Any help would be greatly appreciated as I haven’t been able to find a good answer thus far. Getting Help or Helping Out#. I get it all the time, and if you're dithering every shot like me and doing long subs, the delay can add up. Synchronization . dither 4 pixels in NINA. e. Thanks to Linwood for being the early tester. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Press Copyright Contact us Creators Advertise Developers Terms Privacy NINA PHD2 Times Out, while PHD2 Quickly Starts Guiding - posted in Beginning Deep Sky Imaging: This seems odd to me - after dithering PHD2 quickly returns to Guiding status, but NINA will not know that and will give me the timeout messages and then begin an exposure. Dither After Exposures# Using this trigger will initiate a dither operation after the set amount of exposures. 5/2. I know that you want to stick with your particular software but the only way I know of to dither without guiding is with NINA, which is free software. On random dithers, the declination tracking is, I assume, Anyway after a couple of hours doing cabels, alighments, connections and focusing I was able to start shooting. I have different setups that I use in AP, I am having problems when I switch from one rig to another in NINA . 5px, settle timeout to 30 sec, guiding start timeout to 60 sec, and minimum settle time to 5 sec. - My imaging scale is 1. 4 sp1 Install EQMOD Mount Drivers & Software Install N. Today we're looking at the sequencer in NINA, its options, and how to use it. NINA won't wait to settle after dither (raised this problem before) - posted in Beginning Deep Sky Imaging: This has to be the worst feature of NINA. I am doing a very large dither using NINA's direct guider. Direct Guider is there just for the purpose of allowing NINA to directly do dithering using the main camera. And yes the next time i will do the guiding assistant and adopt the recommendations. I would like to activate dithering but I dont understand whether within CPWI I have to select the PH2D choice and whether in NINA I have So I was looking at it, and nina can be used for dithering without a guide camera It only has one moving axis, and dithering in only one direction is going to create walking noise in your stacked image that will be very difficult to process out. As you increase the Dither Pixels to 3, 4 etc the DEC Dither movement get much much greater as I would expect and the recovery time gets much longer! Table of contents EQ Mounts and NINA Gear in Guide Install ASCOM Suite Install . - posted in Experienced Deep Sky Imaging: When shooting a target through various filters, wether LRGB or SHO, I find that, at least in my setup, dithering has a considerable impact on overhead. What am I missing here? I also had issues while trying to plate solve. Ive configured NINA in equipment to use the direct guider. NINA then starts, pauses and resumes guiding as and when necessary. instead of SGP - posted in Beginning Deep Sky Imaging: Hey folks, Stefan and I just added a Center after Drift plugin that should provide this automatic recovery without delaying your imaging. Reply reply If you don’t use a Tpoint model, you can uncheck that. However, neither instance gave me the option in the NINA guiding When you have a side by side rig on one mount, it becomes hard to dither! Dithering one of the telescopes may affect the second telescope after all NINA has the I thought guiding continues during a dither (maybe I missed the switch) as PHD2 does the dither. These plates are generated from hips2fits a service provided by the CDS Aladin Sky Atlas using the DSS/STScI survey. I have the logs, NINA sequencer setup, etc. Refer to Dithering in Advanced documentation topics for more information about Dithering and how to set the above parameters. My question is can I dither without any guiding? Will it get rid of my walking noise? What can I actually use NINA for? I'm trying to learn NINA advanced sequencer and adding a dither after a sequence of exposures with different filters and then loop back to the beginning of the sequence of exposures with different filters after the dither is finished. For what it is worth, if you go to Options>Imaging then you will find a reset layout button at the bottom right. I adjusted Dither Pixels to give a "Camera Dither Pixels" value of 10, as recommended in the NINA manual. Im curious though whether Im supposed to start/stop guiding with the direct Coordinated Dithering with No Guiding in NINA - posted in Experienced Deep Sky Imaging: I have completed tuning and re-greasing my five year old AP 1600 mount. My dithering range is set to 5 pixels in NINA (albeit I am not exactly sure how it is calculating this), and my gear which is involved in this whole process is listed as follows: SWSA 2i, ASI120MM mini, and Canon 700D. Warning - timed-out waiting for guider to NINA vs. 10 and not the latest beta version (1. In other words, nina N. At first I had problems calibrating PHD2. But while imaging over the last two days, I Problem 5: Dithering will be necessary and in this example we have chosen to dither after 4 exposures. I have a Paramount MX that is controlled through TSX A plugin for NINA that dynamically selects an optimal target for imaging, allowing for unattended, multi-night, multi-target automated imaging. Enable tracking offsets – Allows changes to the tracking rate to I have read a little bit about NINA and have had it recommend to me. Tech@ZWO. I then adjusted the Dither Pixels setting in NINA on the Equipment - Guider tab. I don't have any guiding setup and use a 200mm focal length lens with my DSLR on an AVX mount. Settle Pixel Tolerance# In order for N. May not put you back yo where you were but it will put everything back so you can start again 🙂 Settling Time in PHD2 - posted in Beginning Deep Sky Imaging: I have been reading a bit about settling time during dithering while guiding. I want to use the NINA synchronised dithering, can someone please tell me what is the value of After exposures mean? I want dithering after every 10 mins frame, sync on both scope. When it comes to dithering, I understand that the more In this video I take you through the step to connect the Star Adventurer GTI with N. I have tried many combinations of numbers and the problem is not solved hence my plan to switch Dither Settling Time is how long N. In order for N. This plugin draws heavy inspiration from Tom Palmer's Target Scheduler plugin and shares a number of similar features. NINA nightly v2 #49, PHD2, ASCOM, latest StarGO). SGPro, unguided dither and NINA - posted in Beginning Deep Sky Imaging: Hi all, I have a 10micron GM1000HPS that has been working out great but have never really quite figured out how to get dither to work in SGPro. Phd2 handles the guiding and dithering, NINA handles image capture and tells phd2 when to dither in between exposures. . As you increase the Dither Pixels to 3, 4 etc the DEC Dither movement get much much greater as I would expect and the recovery time gets much longer! When I started with NINA I messed up my imaging tab. This is my configuration for guiding in NINA and PHD2: Dithering: 5px with a scale of 6. 60 to 0. 4 and when I did get clear skies I had already updated the app to v1. As I set dither to random in PHD2, the size of the spike does vary a little. You run two instances of NINA, hook each one up to the camera you want to control. let's go capture some nice astrophotos!#astrophotography In NINA with a Dither Pixels of 1 or maybe 2px the DEC backlash / Dithering is somewhat controlled. If I were to dither, say, every 3 frames, I could considerably minimise dithering (three or four times less) if I rotated through I often hear how intimidating the advanced sequencer in NINA is. 's Discord chat server is a great way to chat with the creator Stefan Berg the N. I changed it to 0. One thing I noticed after working with it for a couple hours is that NINA will take upwards of around 30-40 seconds to finish its dithering sequence NINA and PHD2 Connection (Guider) - posted in Experienced Deep Sky Imaging: PHD2 connects to the guide camera, not NINA - NINA issues dithering commands. The strange thing is that I'm supposed to be dithering with NINA. Tip. simon. To enable PHD2's internal server, go to PHD2's Tools menu and ensure that Enable Server is selected. NINA developers have just released a synchronized dithering plug in. Posts: 895;. Lots of good info there. com/ogecko/alpaca-benro-polar Page 1 of 7 - Dithering: how many pixels - posted in Experienced Deep Sky Imaging: Hope it´s ok to ask something that kind of has been brought up before, but I haveńt been able to find a specific answer. Mount slews from the park position, plate solves, adjusts and then gets on with the In the SAM consol app there is a setting for automatic dithering, but it requires a dithering range. RZM Video Tutorial in Italiano sull'uso di Nighttime Imaging 'N' Astronomy (NINA), un software gratuito per la gestione di un setup di Astrofotografia. Dithering is not costless, it's a tax on exposure time and there's a tradeoff of losing SNR to either insufficient or excessive dithering. But after another calibration this problem vanished. Its only purpose is to effect a dither directly to the mount when command to via the normal Dither-related I had both my scopes up and running using the latest NINA and I had downloaded the synchronization plug-in. Hi, I’m Sascha Wyss from Switzerland. If "Dither RA only" is checked, the dither movements will only be performed in RA. I usually would dither every frame (or every other frame cant remember). I know you can synchronise the dithering operation on two instances of NINA, I'm running a dual rig unguided - so don't use PHD2. However, the synchronised PHD dithering only works with nina 1. The 3 star polar alignement is awesome, I can shoot from my south facing balcony without even seeing Polaris, it would probably be a good investment to add a small guiding system to your setup. (When we estimate about 20 seconds per Dithering With PhD2 and Nina [Deep Sky] Acquisition In my case, dithering usually takes some seconds including settling time. I do not use PHD2. If you have a way to set nina up to recenter the image every so often, that would help as well. But from time to time, I see those timeout messages on one of my mounts which has more backlash in its mechanics. Dithering is a special process that should allow you to fix some annoying problems in your astro images. I have read a few posts about that and some guys said that i don’t need to dither if i don’t use a autoguider,some said that i should use APT dithering or NINA’s direct guider device. I personally switched off dithering as it just won’t settle, unfortunately I didn’t get the opportunity to try in v1. So let's do it, by setting Dither every # to 0 for all Smart Exposures and instead add a Dither Instruction after the last Smart Exposure ! NINA, 10 Micron and Direct Guider (for dithering) - posted in Beginning Deep Sky Imaging: Hello. Failed third night, second object: Stopped tracking 11!!! minutes before meridian. If I want to cancel out this walking noise, what range should I use? settle and continue guiding is about 30s. com is the leading portal for astronomy news, classified ads and telescope reviews. If I don’t dither the guiding is fine and just sticks at around 1 arc second Part 3 of setting up the side by side dual telescope setup. Ive been using it for years and it does not wait for the dither to settle. In NINA sequencer I set dithering after each frame. RASA8, SSAG, good cooled camera, enabling auto-alignment, guided imaging integrated with SC). 's New Synchronized Dithering - posted in Experienced Deep Sky Imaging: Hello folks, For me synchronized dithering is one of the last challenges to running an array scope setup. NINA Direct Guider Help - posted in Beginning Deep Sky Imaging: Hello! I dont have the money right now to buy a guiding system, so Ive been looking for alternatives to help dither my images. After the first dither completed successfully, I let the plan run all night. One can spend many, many hours and much money on guiding in order to be able to dither. Dithering . 5. 0 Install Ascom 6. Changed DEC algorithm to the default Resist Switch from Hysteresis. Then tell NINA how you want to dither - and to send the commands to PHD2. NINA, PHD2 (auto-guiding software), APT (Astrophotography Tool), The problem is, that two ASIAIR computers can't sync themselves when it comes to Dithering. 1 and after I didn't find any guide settings tab in, made settings in PHD2. I wasn't using sequences, but the logs I looked at for my mount clearly indicate that phd2 is dithering during calibration. https://skywatcher. As you are not using a guidescope, you've been using NINA's The number of pixels to dither is specific to your combination of primary camera and guide camera. My scope and main camera have an scale of 3. Not only that, but guiding I have not done the rigorous testing you describe here, but I have done many hundreds of unguided sessions with tens of thousands of subs, all dithering after every exposure. Examples: Dither=1, LRGBLRGBLRGBLLL: LRGBdLRGBdLRGBdLdLdL; Dither=2, LRGBLRGBLRGBLLL: LRGBLRGBdLRGBLdLL; Dither=3, LRGBLRGBLRGBLLL: LRGBLRGBLRGBdLLL nina N. When a dither is initiated by PHD2 a random move of the mount in RA/DEC is issued, the maximum amount of Setting interval/dithering time between frames in NINA - posted in Astronomy Software & Computers: So the other night, I had my first full run through while auto-guiding and controlling my DSLR via a PC through NINA. It does not do "guiding" and you must load one of the approved guiders from the dropdown list. YMMV. Is there a way to have NINA control NINA, Dither, & Short Subs - posted in Beginning Deep Sky Imaging: I currently use DSLR + Backyard Nikon, and had in the past set my exposures longer (1-3 minutes) based on histogram only. The second is just along for the ride. It works by doing a platesolve in the background every N images (configurable), It looks like the dithering routine you used only moved in one direction and constantly in the same direction. I thought guiding continues during a dither (maybe I missed the switch) as PHD2 does the dither. Ich glaub ich seh doppelt? - Heute werden viele Photonen gesammelt! Denn ich habe das synchronisierte Dithern (synchronized dither) mit 2 N. com/download/software/ NIGHTTIME IMAGING 'N' ASTRONOMY⬇️⬇️⬇️ Description ⬇️⬇️⬇️Vous me l'avez tellement réclamé, voici un soirée test avec le logiciel NINA. I have some basic questions, but suggest questions I should be asking if It helps get the point across. Works perfectly so far. NINA. Think i can see the amount of backlash and let PHD2 take care of it. Synchronized PHD2 Guider will synchronize your Dither requests between multiple instances of N. The two instances can also talk to each other to synchronize dithering (when an exposure on one camera ends, and a dither is due, it will wait until the exposure on the other camera ends, do the dither, settle, then start both cameras exposing again). I'm trying to get synchronised dithering to work. Synchronized Dithering: Multiple instances of NINA may work together with a single instance of PHD2 to accomplish synchronized dithering. I have loaded it and tonight may be my first try with a three scope array. To research past questions, bug reports, or file your own bug report or question, please use the Issue Tracker. , 32"/px. And yes, with a blank page and a boatload of instructions, it can be overwhelming. From the new Framing Assistant and Flat Wizard to direct PHD2 management and synchronized dithering between multiple instances of NINA, Stanley explains how they work and In-depth tutorials and set-up videos of NINA to understand its more advanced features and get the most out of NINA. 70 with no spurious Ra or Dec spikes , fairly stable , but dithering was super aggressive both in Dec and Ra. I have a couple different setups and am trying to workout the guiding and dither settings for them. usual total RMS is 0. After that it just timed out after 180s. I understand if it is one rig it will save it automatically, but I I use a different scope , it keeps the Nina and DSLR - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: I am looking for anyone with experience using NINA, a dslr, and PHD2. Reading the docs, it may have all the features Im looking for but Im not sure. If I dither at 7 pixels in NINA, my imaging camera is actually moving just over 11 pixels. I cant find an option on the SynScan Pro app like in the SA console as I used on SA2i. It works by your first instance of nina acting as the server and the second piggyback instance of nina as a slave. I read that Sky X will dither but only if you control the imaging camera in Sky X. My main concern is why the overshoot in RA. I don’t have guiding yet in my setup, so been relying on the Direct Guider for dithering. The interesting thing is that it doesn’t Yes, PHD will only dither (and acknowledge to NINA that it is doing so) while it is guiding. You just need a guidescope, camera, phd2, and NINA. Look at what your RMS is and set it to say 2x that and see how you go. NET 3. A astrophotography software. It simply NINA developers have just released a synchronized dithering plug in. You can also do just fine with an asi120mm mini, it's a little cheaper. The resultant move in pixels for your PRIMARY camera is what you want to move by 10 pixels (per NINA recommendations, anyway). I don't have a guide cam so I connected to NINA's direct guider, set the dithering to 50px (under guiding settings) and set it to dither every frame. When NINA plate solves, it uses my main camera for that. Does anyone know how to save my profile and loaded next time. for anyone willing to help me figure this out. Guiding can be disabled during a slew, but a dither is not a slew. It loads with NINA, (as it's built-in) but does not guide. I would just boresight the piggybacked camera while the other camera, via one instance of NINA, would do the aiming, framing, etc. Note I don´t have an autoguide camera/scope to use PHD, I read that is possible to dither using that. There are numerous tutorials online for setting up PHD2. The free way is to use nina and the paid way is Voyager. Dither causing guiding errors - posted in Beginning Deep Sky Imaging: Im wondering if some of you more advance imagers could give me your thoughts on this. For this example run it will take 80 Dithers. 67"/px, so I'm dithering 8-9px. You have to set up the mount and guide camera profile in PHD2 (and perhaps you have). Than you very much . simon Sorry for the confusion; this should have been: Dec mode is set to OFF and RA only is turned on. This is very unlikely to be the same. Attached is a screen shot of my scenario. Trying to find some software to trigger the camera. Approachable. I use ASTAP plate solving and never have an issue with a plate solve for initially getting the target and doing the I’ve recently been trying out NINA with my setup and it’s been a learning curve. Set camera to cool 2) Go to PHD2 (which opened when I connected guider in NINA) and run calibration and GA in there. My dithering was abnormal the other night , guiding was Ok around 0. Cheers, Chris. You can always adjust it to suit. 3) Back to NINA to set target, framing, sequence and start capture. It does this by setting up communications between two or more running instances of NINA and then synchronizing some activities via custom instructions in each sequence. I use the advanced sequencer and want to run the Center After Drift procedure in NINA. Dithering was set at 2 pixels. contributors and fellow users. A setting of 10 pixels in NINA tells PHD2 to move the GUIDE camera 10 pixels. Issues with dithering and settling - posted in Beginning Deep Sky Imaging: Hi guys, I am having some issues with dithering and mount settling that are creating a little bump and streak on the image following the dithering. Dithering during sequencing; MGEN-3 support will appear in a future release; QHYCCD for providing a QHY183M and CFW3 filter wheel to test and verify NINA’s native QHY camera and filter wheel drivers; These N. I know NINA has a direct guide option, but every time I have it set to dither, nothing happens (in the morning I still get the same walking noise). Please help. Just before dawn, I reset the RA from Hysteresis back to PPEC. CS, Jeff Got it, thanks. 5px and Page 1 of 2 - Unguided dithering: current state of hobby - posted in Beginning Deep Sky Imaging: A few years ago dithering was and probably still a great way to improve DSLR images. Many sensors produce fixed pattern noise, which can include hot Guiding, dithering, and absolute encoders - posted in Experienced Deep Sky Imaging: I’ve acquired a used AP with Absolute Encoders and I’m trying to learn the control relationship between guiding, dithering and using absolute encoders. The N. The Scheduler instruction can optionally schedule dithering for you. Can I still use NINA to sequence my lights and add dithering? How about plate solving/slewing and polar alignment? Appreciate any insight. Problem is during dither, I often get one of the following message in NINA: 1. My kit consists of 2x SW Esprit 100 ED, 2x QHY 268M CAMERAS, Different profiles in NINA - posted in Astronomy Software & Computers: How everyone. Decided to use NINA 2. I set to dither every 2 frames, with each frame is 60s exposure. Place your astronomy ads, read the latest news articles and check out the current reviews of newest telescopes and equipment.
