Thanks for your responses.
Ryan - Thanks for that visualization. That give me something to think about.
Yes, I started to wonder if it is an intrinsic limitation of the equipment. Keeping your description in mind, there might be some "positions" that have less errors? like if the object being photographed is closer to the meridian?
Perhaps if I imbalance the weights a little might reduce the chance of the "jumps"? i.e. something for motors to work a "little" against...to dampen things? Perhaps?
I think Alex has a point, I need to do a bit more testing, to try and understand what makes it more likely, less likely.
Sunfish, the mount is a "Celestron CGX German Equatorial Mount and Tripod". What do you mean by "Also mirror slap on a DSLR if you do not set up for the mirror to lock at least a few seconds before the shutter fires with a remote." Vibration of camera when it starts the photo and ends photo?
Yes, I should probably look at a guide. Once I understand issue a bit more, I may look at getting one.
Thanks!!
Joe
