Celestron C80 Edr |
| The C80 EDR comes on a heavy-duty German Equatorial mount with ultra-sturdy 2inch stainless steel legs and center tray for superior rigidity and vibration dampening. The new German Equatorial mount has precision worm gears on both axes for extremely smooth performance. The key element that makes this system the most stable in its class is the NEW heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. The CG-5 also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments. The C80 EDR is packed with great features and excellent optics including our high quality ED glass. The refractor style 80ED (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. With a focal length of 600mm (f/7.5) the 80ED refractor is well suited for wide field astrophotography as well as nature photography. This telescope comes complete with a 20mm 1.25" eyepiece, erect image diagonal and 6x30 finderscope. CG-5 Mount — Precision engineered for stability. 80mm (Apo style) refractor. Fully multi-coated optics and high quality ED glass for clear, razor sharp views. 6x30 finderscope to help accurately find objects. 20mm Pl? eyepiece (30x) included for wide field viewing. Heavy Duty (CG-5) German equatorial mount. Ultra sturdy 2inch diameter steel tripod with accessory tray. Slow motion controls for smooth tracking action.
