Mounts that are gear driven, as opposed to ones that are belt or directly
driven, should not be well balanced when fully set up. All gear drives have some backlash in the system, and if the system is accurately balanced the
scope can flop backwards and forwards a little, and even a little movement of your target can be irritating. With equatorial mounts you have the added nuisance of tracking being affected when imaging. Your azimuth axis
wouldn't flop enough to matter, but the altitude axis needs to be balanced a bit nose heavy so that the motor which is raising the scope remains fully engaged all the time. 600g + possibly a heavy eyepiece seems a bit on the heavy side. I would velcro a 500gr weight onto the rear of the scope. You can
buy or make a bar with a sliding weight for Dobs.
