Orion® 8" f/3.9 New­to­nian Astro­graph Re­flec­tor

Sky at Night Magazine - - ADVERTISIN­G FEATURE -

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.
