Are you sure you were actually tracking? Even a very basic plonk down the mount facing south should give you nice round stars at that focal length and 1 minute exposure time as long as the mount is tracking.
hi Greg. I was doing my version of what I thought was tracking haha that was to press the 8x RA drive on the hand controller then hit the shutter. I tried both the left and right RA directions including 4x and 2x speeds. I also tried doing the same in DEC to see if that would change anything...it didn't. I have never tried tracking imaging really before and I believed that was how it was done. Maybe not . The mount is a eq3 with RA and DEC motors and I was using just the rings with the piggy back thread to mount the camera. I have read people guide by looking through the EP and counter the drift that way. I may try that way? So I thought I was tracking but no matter which speed I used, the results were the same ? back to the old drawing board haha
