@Jared, I'm sad to report I don't think the 18.104.22.168 update fixed the issue. I recently did get out and was able to try the new update, but the problem persists. Unfortunately, in going to look for the log file (it's been over a week ago that I ran this sequence), it appears my log file is no longer available. It seems to have been deleted (not sure if SGPro deletes log files automatically or not). Anyway, I don't have that to post here, which may not be very helpful, but the behavior is the same as it was in the previous iterations. The flip reported that it was successful, but it was off in both RA and DEC (see attached pics. These have been overlaid so they line up with one another. You can see the offset from the preflip file (frame 10 - randomly chosen) to the post-flip file (frame 58 - randomly chosen)...please ignore the terrible subs - the data from the night was not very good). I'm hoping to have another shot this upcoming Friday - not sure what would be more helpful: a) running another sequence with the beta version in order to post the log file or b) rolling back to 22.214.171.124. I'm guessing the former, given that there seems to be a consensus that 126.96.36.199 is successful.
Thank you, again, for looking into this. Please let me know what else I can provide to help you debug this!
