Description

Celestron Nexstar 4SE Telescope and Additional Box of lenses and filters. The telescope has only been about a half dozen times and I am selling as I don't have the time to use it. This is an introductory telescope. It is set up by entering your location & using a finder plus one of a few methods of triangulation using the motor and hand-held controller with its computerised database of 38,181 accessible objects. Visible objects can then be automatically located. The standard telescope comes with its original manual and an extra accessory box of 3 Plossl lenses and 4 filters in addition to the original lens. The full list of lenses & filters is: Plossl 25 mm lens (originally supplied); Plossl 6mm lens; Plossl 12.5 mm lens; Plossl 20mm lens; 2x Barlow lens Moonglow and Slyglow filter; Filters Red (23A), Yellow (12), Blue (80A) The telescope motor is battery operated & there is a battery for the finder lens. *MANUFACTURER'S SPECS (ORIGINAL LENS).
