If this is a 16" dob you will be lucky to get much more than 0.1-0.2 second exposure before trailing occurs (and this assumes there is no shaket from the camera shutter/mirror). With a 10 second exposure (assuming you use a tracking platform) you should see more than your eyes alone.

Autofocus is not possible with the telescope.
