Sky-Watcher 80/400 Refractor OTA

The Sky-Watcher 80/400 Refractor OTA is a two-element, air-spaced, fully multi-coated objective, achromatic refractor.

This scope is ideal as a guide scope on bigger astronomy set ups. It also makes a superb terrestrial telescope when mounted on an alt-azimuth mount and used with a correct image diagonal. The compact length of the telescope makes it convenient for it to be packed up and stored away while not in use, or in transit.

Fully Multi-Coated Objective Lens
This 80/400 Sky-Watcher Telescope has an 80mm aperture size and a 400 mm focal length. Perfectly suited to terrestial viewing, occasional celstial moon viewing and low powered astronomical observation.


NOTE:  This OTA does not include a diagonal, eyepieces, or tripod/mount. Tube rings and tripod mounting plate are included.
