I have a used Orion SkyView Pro 8" Equatorial Reflector Telescope and will pretty soon start trying to photograph objects I see. I know this thing used to have a motor, but what can I get that will do the trick and follow the object I want. Also the camera I'm using is an old analog camera, or should I get a brand name camera that is specifically for this? How do I even know if it will fit on my equatorial mount?
