Ok, I’ve been successful in creating 20 grid mosaic before, but the last few nights I’m getting rotator errors (manual rotation) after the first few targets. I’m using Slew to and Center on settings in the targets along with the Rotate camera to setting.
Tonight the first two targets were fine, but then I got this on the third target of the mosaic.
I don’t think I have flex in my telescope train. But I’m baffled as to why the angle is off. And even if I correct it, the next target might be off again too.
In addition to what Chris said, I have accidentally knocked my camera and it has loosened/tightened on its T-thread and given a little wonk to my images. It is easily done. The other thing to look out for is that some of the rack and pinion focusers may have negligible lateral flexure but it is possible to rotate the focus tube slightly. My WO and one of my Taks is like that.
Thanks for the replies. I checked several targets in SkyX and the position angles are always the same. Rock solid. So I still don’t know what’s causing SGP to fail. After disabling the “rotate the camera” in each of the targets, I had an auto center fail last night on the 7th target. In looking at the logs, instead of 42.6 degrees, the angle of the last plate solve was 43.86. This happened after I went to bed, so I couldn’t plate solve it in SkyX to see what it reported the camera angle to be. But, the thing I don’t understand is that I had unchecked the rotate camera box, yet it still tried to rotate it. Is that because auto center was on?
Also End of Sequence (Park Telescope) didn’t run. I thought by ticking the Park Telescope when sequence completes box in my Equipment Profile Manager, that this would happen automatically when there was a sequence failure. Thank goodness I have a Paramount that has limits preventing the telescope from running into the mount!
I now understand that this needs to be done in the Control Panel if the sequence is already generated with my user profile and the user profile was changed in mid-stream to include park the scope upon end of sequence.
