Orion® 8" f/3.9 Newtonian Astrograph Reflector

Our 8” aperture deep-sky specialist is an ideal choice for wide- eld imaging with its 8”, f/3.9 parabolic primary mirror and large, 70mm minor-axis secondary mirror. To eliminate o -axis light, the dual-speed 2” (50.8mm) Crayford focuser is installed 6.3” (160mm) from the front of the optical tube. A steel reinforcing plate eliminates focuser exure, even with heavy imaging gear attached.
