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. It allows you to view detailed vistas of star fields, clusters, nebulae, planets and other celestial bodies. It makes a fine terrestrial telescope when mounted on an alt-azimuth mount. 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, providing plenty of light gathering ability for a beginner. You will be able to view the Moon, planets, star clusters and other deep sky objects with crisp, bright clarity, and also view terrestrial objects during the day. When you combine the fast focal ratio with a digital camera, you will be able to get a wide field of view. 

Whether to be used as a beginner's telescope, a "rich-field", a backup, a guide scope or a travelling telescope, the very reasonable price makes it a choice to seriously consider. This optical tube assembly is held firmly by hinged, felt-lined tube mounting rings which allow easy installation and optical tube rotation and balancing. Mounting one of these telescopes on an alt-azimuth mount or a photographic tripod is quick and simple with the supplied multi-function mounting plate. This telescope performs well as a fixed aperture lense for both astrophotography and terrestrial photography. The "fast" focal ratio, combined with today's high speed film, make it useful for capturing lunar and solar eclipses, as well as nature photographs.  A T-mount thread on the eyepiece holder allows direct attachment of an appropriate T2-adapter and the optional extension tube gives closer focusing for terrestrial photography. 

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