2” Dual Speed Crayford Style Focuser
The 2” dual speed (10:1) Crayford style focuser is an essential component of this telescope. It provides fine focusing and a good mount for a camera.

October, 2010, Update: The stock dual speed crayford style focuser on the AT8IN does a reliable job of focusing. However, I have found that it will not lift my Nikon D700 (1.82lbs. w/o battery) to focus. Focus may only be obtained by lowering the camera. Therefore, the stock focuser is a subject for replacement.
