Notice the middle part of the photo is lighter than the edges? Most scopes have this to some extent. It becomes amplified with image stretching. You could always setup early and take the flats before you start the session, but you have to keep the camera orientation the same throughout the imaging session.

Sorry no idea on exposure for your circumstances. I think you are limited anyway being unguided if you are still using the EQ3.
