How is the magnification when you use a camera in prime focus??

At prime focus, it just uses the telescope as a telephoto lens, so if you have a 1,000 mm FL telescope with 200 mm aperture (f/5), say, it becomes a 1,000 mm focal length telephoto lens with fixed aperture of f/5, or 5x the magnification (1/5 the FoV) that you would get with a 200 mm lens, for example.
