The pinnacle of Celestron ED scopes, this refractor is packed with great features and excellent optics. The refractor style 100ED (APO) features a 2" rack and pinion focuser and has a bracket that can adapt to a photo tripod. ED glass provides excellent color correction and razor sharp images and virtually eliminates chromatic aberration usually seen during planetary and lunar viewing. This telescope comes complete with a 20mm 1.25" eyepiece, erect image diagonal and 6x30 finderscope.
