I was imaging a lot over the last week and was doing 150 shot runs. I’m using a 10u so I use mount dithers. The random dithers seem pretty predictable; it also results in significant movement off center when you’re taking 150 pictures. 

would I be better doing multiple jobs with 25-50 pictures so I get a recenter in? Can it do the movements in a less predictive right and down motion? So it goes around the coordinates?

 

As workaround probably don't dither after each frame. But yes you can split it to smaller jobs so it recenter before each batch.

I think there is a known issue with that at the moment, so the workaround is what @Nou has suggested. When I dont use a guidescope I use this method of periodic realigning. You will need to find out the maximum number of frames that you can capture before drift is noticeable and then create appropriate sequence size. That way you can use dither at set intervals with less risk of image going off the track.
