CELESTRON  • 80ED 3.15 inch Refractor  •  52280

The pinnacle of Celestron  ED (for Extra Low Dispersion Glass) Spotting Scopes, this refractor is packed with great features and excellent Fully Multi-Coated optics. The refractor style 80ED (APO) features a 2" rack and pinion focuser and has a bracket that can adapt to a photo tripod or attach to Celestron’s Advanced GT equatorial mount.

ED glass provides excellent color correction and razor sharp images for serious nature and bird watchers, and virtually eliminates chromatic aberration usually seen during planetary and lunar viewing. With a focal length of 600 mm (f/7.5) the 80ED refractor is well suited for wide field astrophotography as well as nature photography. This spotter comes complete with a 25 mm 1.25" eyepiece, erect image diagonal and 6x30 finderscope.
