No Angular Deviation Detection

tomstein

After a 1st session with a given framing, I want to go back to the very same framing (including camera rotation angle) on following sessions. ASIAir should support this, as is demonstrated e.g. here: https://www.youtube.com/watch?v=UmhYX400tlY
When I follow the same steps though, this menu never shows up on my screen:

To be clear, I am in Preview mode, go to image management, go into autorun folder to pick an image from an earlier session, GoTo. The mount slews and centers, but skips the point 'Angular Deviation Detection'. I have tried a ton of things, like going from different menus, doing extreme camera rotation to force the unit to detect the wrong angle, but all to no avail. My only work around is to frame the target manually in sky atlas, trying to eyeball-match the previous framing as well as possible. Then I use the 'frame' menu to utilize the rotation assist and that works, but it is still very unprecise and I lose more at the edges than I want.

This problem was posted by another user in an older thread here:
https://bbs.zwoastro.com/d/15898-asiair-v21-has-been-released/126
but there was no real follow-up. So I am wondering if this is a Firmware related issue or I am doing something wrong?

Using ASIAir 2.1.4 11.06

Hello @tomstein
I have the same question about this particular menu because I don't see it either....
However I think I can add an improvement to what you are doing: when you go to the image management and select the frame from an earlier session you can click on the info ⓘ button and it will give you the exact angle of your reference frame.
You can then replicate this angle in the frame menu and you don't need to eyeball anything.

tomstein Thank you for your feedback. Could you please let us know if you are using the iOS or Android system? If you are using the Android system, there is indeed a bug, and we have fixed it in the 2.1.5 public beta version. Here is the link to the 2.1.5 pbulic beta version：https://bbs.zwoastro.com/d/18455-asiair-v215-public-beta-released

Hello nicolas Thanks for the hint! I get about 1 cloudless night per month this time of the year, so it will take a long time until I can try this out. But I will definitely give this method a go.

Regardless, it seems this is a global issue then ... and I am wondering why I have not seen any mentioning of this anywhere else even after hours of searching. I would assume tons of users would use this function frequently, like anytime one is about to continue a session and has rotated the camera inbetween, e.g. for store-away. Hopefully ZWO is aware about it and will put it back into a future release.

PMTeam@ZWO I appreciate the feedback! Yes, I am using Android (Galaxy S23 - version 14). Glad to see this is already known and fixed.

I have never installed a beta before so please let me ask: I just install it directly from the link you provided. Then in the future, when the official 2.1.5 version is out, I can just update normally and do not need to manually deinstall/remove the beta, correct?

PMTeam@ZWO

tomstein The purpose of the beta version is to collect user feedback and make necessary optimizations. Once the official version is released, you can delete the beta version and download the official release. For Android systems, you can download it from the Google Play Store or from the ZWO official website.

PMTeam@ZWO I just had the chance to test the 2.1.5 beta and was able to confirm Angular Deviation Detection is working again - however, not immediately. In fact, I tried several of my files from previous sessions by image management -> autorun folder, and the detection would be skipped. Then I took a shot in preview mode, solved and saved it. For this file, the angular detection check actually worked. This got me thinking and I checked the 'angle' information in the 'info' menu. Indeed, for all my previous files in 'autorun', the angle information was 'N/A' while for the preview file, there was an angle.

So my assumption: the check only works if the file contains angle information. Can you confirm this?
Why do my older files not contain angle information? Did I miss a setting or is that firmware related?
Or does the check generally only work on files that are saved from the preview?
