Goto only is enough for locating objects, need tracking to follow based on rotation.
I have a 12" DOB and done a lot of AP. Moon easy, Planets hard. I am almost finished a EQ mod for my DOB in which I hope to get much higher res shots, wishing for better skies.
GOTO with tracking is no good for Deep Sky due to rotation, you would need to get a field de-rotator to compensate for the image twisting while tracking on a DOB. EQ is the only way. My mount is expected to be rough prototype maybe but should be perfect for Moon and Planets, I hope that my construction skills are good enough to do good widefield AP. Still waiting for bearings from Germany.
