I will email it to you. It is a jpg file but you can see that the stars are round. Time of photo is 21.35 on 20240803 which matches the glitches in my phd log graph and shows that the 5 min exposure the stars are round and do not show signs of the DEC glitches. I think it is the asiair that is displaying the incorrect information. I also have noticed over many nights now that the guiding is initially quite good at around 0.6, 0.7 rms and after a while it gets worse going up to 2 rms, but when I clear the guiding graph and watch the numbers, it stays at around 0.6, 0.7 again for a while then creeps up again, and so I clear the graph again and so on. There must be a cumulative error in the aisiair for the ioptron mounts, as I have read that others are having the same issues. Please advise.
many thanks again
Nick
