This refractor is packed with great features and excellent optics including 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.
Mounted on the Advanced GT Series computerized mount, this telescope has some high performance software and hardware features. Operated by Celestron proven NexStar computer control technology the telescope has a 40,000+ object database with 400 user-definable objects and expanded information on over 200 objects. Custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable star; solar systems; objects and asterisms.
Using the RS-232 communication port on the hand control, you can control the telescope via a personal computer and our new flash upgradeable hand controls allow you to update your telescope's operationg software via the internet. An autoguider port is also included for astrophotography.
