Asiair guide calibration I found this blog article, and it addressed a number of issues and questions that I couldn't find anywhere else, so I am sharing it. Otherwise, ASIAIR will clear the previous calibration for you. The problem I have now is stacking – apparently I did not capture my darks and flats correctly. Perfect for First night with ASIAir auto-guiding - posted in Beginning Deep Sky Imaging: Received ASIAir Plus 5 days ago and on Friday night had the whole rig set up and working with the CQ350, at a Bortle 1 site with quite good seeing, visually on Jupiter it was around 8/10. 5 arcsec, because asiair switches to a very fins scale at that point, showing very small changes as large on the graph. Hey all, looking for some feedback on some odd behavior from my asiair a few days ago. At 3:30 seconds he shows how PHD2 calibration step is calculated based on the guide scope focal length. If you encounter an error, send us the log and we will solve it. The graph shows the movement of the star formed by the guide pulse sent by ASIAIR during calibration. This guide will take you through understanding these values and how to adjust them for optimal results. Members Online. Page 1 of 3 - Setting up ASIAir Pro - posted in Beginning Deep Sky Imaging: Since the general consensus seems to be that you have to guide, I decided to get the ASI Air Pro rather than drag a laptop out into the field. Once finished, I stop guiding, send the mount home, then send it to the actual target and start guiding again, utilizing the calibration as just conducted. Occasionally it worked but rarely. I’m using the iOptron Skyguider Pro and the ZWO guide scope. 5x guide rate, the mount will move by 37. I started the night out with no issues, ran EAF, guide star calibration, plate solve and PA just fine (personal time record). PHD2 will try to move the star by 25 pixels during calibration; so the 2 pixels per calibration pulse will finish calibration in 12 or 13 steps. It's confusing because Asair-pro controls the go-to's fine and the (Asiair-pro) 4-way arrow I watched this YouTube video this morning: "New ZWO Guide Scope and PHD2 Settings" where the gentleman switched from the same guide scope I have to a larger 60mm scope. EDIT - I don't have an ASIAir but if auto-calibrate does what I think it does; yes turn it On. When that happens, I open the calibration panel in the guidescope view and delete the current graph settings The graph shows the movement of the star formed by the guide pulse sent by ASIAIR during calibration. The guide scope is well focused and able to locate stars fine, and I havent changed any of my previous settings in which guiding was working ok. As If number of steps <4 – calibration = poor - adjust calibration step to smaller number in the guide menu If number of steps too many – ASIair wont reach 25 px in reasonable time – you get a time out message – so adjust calibration to larger number - try 5000 If imaging towards zenith – increase calibration step Here is the guidance from PHD2 website. No matter what aggression and max duration settings I use - the result is the same - calibration does not seem to be doing anything, and the application tries to guide the mount without absolutely any visible effect. It's confusing because Asair-pro controls the go-to's fine and the (Asiair-pro) 4-way arrow ASIAIR Pro guiding "guide" - posted in Beginning Deep Sky Imaging: Hello all, I wanted to share this link to a write up regarding the ASIAIR Pro and its guiding process.

By now you are likely familiar While PHD2 is calibrating, ASIAIR will display the number of calibration pulses ("steps"), and how much the star has moved in pixels (what ASIAIR display as "dist"). Add to my manuals. This only started happening yesterday. It This version of ASIAir introduces a new feature I call AutoFlat. I hope this has been helpful and simplifies your calibration workflow. I guess this is a quite common setup with AM5 and the guide scope choice? Any suggestions on Guide settings, exposure settings etc to improve Autoguiding is essential for long astrophotography exposures.

I can't imagine that not connecting to a main camera would impact on the guide camera's ability to calibrate though? Unless as Gilesco mentioned, the settings might have to be a ASIAIR Guiding Calibration . 5mm x 2. I figured it was the used AVX mount so i sold it and bought a new iOptron CEM25p. John Dobson passed 10 years ago today - RIP youtu. This manual gives you detailed reference information and descriptions of each function in each step of use. 5), this comes to . Why does this Before using the ASIAIR, it is necessary to align the polar axis on the equatorial mount. I kept getting an error that the guidestar did n Tap this button for the guider calibration data. After setting the EXP exposure time, touch this button to start refreshing the image captured by the The ASIAir will switch from calibration to guiding even though the cross hairs are not on the star but within the green box. thank you so much, i will try to reduce the back focus from reducer to camera sensor as Once you are happy Go back into ASIAIR and choose the mount speed as 8x (if the mount is set to MAX or any higher than 8x it will prevent the guiding module from calibrating correctly) 13. I have tried to change the calibration parameters, but it does not make any difference. The accuracy of the polar axis calibration will affect the accuracy of the guiding and the GoTo. 75, 0. As recommended above, first thing is to start a new guide calibration near the celestial equator but awa from the moon. How to restore ASIAIR OS 2021-07. "Guide calibration" is simply a process of measuring the camera pixels units (x and y pixels) relative to the sky coordinates (RA and declination). 9) for your mount, and the best Aggression, and Exposure, but first you need to Guide calibration failure "Star didn't move enough" problem (ASIAir) - posted in Beginning Deep Sky Imaging: First night out trying to get my new equipment working.

Supported ZWO CAA: If it has been turned off, please try polar calibration again. In reality, if the guiding isn't catching errors quickly enough, you could try increasing Aggression they are over on the guide cam setting page of ASIAIR. However the easiest way to generate calibration frames on the ASIAIR is using the Live plan feature, as this process not only shoots the frames, but also combines them into a I calibrate the guiding by pointing it at the celestial equator, to get the most movement during calibration steps. 25) guiding speed. As I mentioned above, re-calibrating PHD tends to help. 376. By now you are likely familiar with stacking and with that the calibration frames that go with it, bias, darks, and flats. If after 60 steps, the guide star has still not moved by 25 pixels, it will report that "star did Asiair pro guiding calibration invalid after meridian flip - posted in Experienced Deep Sky Imaging: I am using Asiair to guide my mount.
