Product description
Startravel-102 AZ-3 Refractor

This SkyWatcher 102mm (4") f/5 telescope is a two-element, air-spaced, fully multi-coated objective, achromatic refractor, which can give exciting "rich field" astronomical views. It can provide excellent vistas of star fields, clusters, nebulae, galaxies, planets, the moon and (with correct filtering or by projection) the sun. It is also a fine terrestrial telescope when mounted on an alt-azimuth mount or a photographic tripod. Crisp images at a reasonable price make it an excellent beginner's "first telescope", or a great traveling telescope for a more advanced observer. Similar to the popular 80mm f/5 refractor, this larger aperture model has more light collecting power at the same focal ratio and accepts 2" diagonals for awesome wide field views, while only a small amount to chromatic aberration and weight. Weighing about 3kg. (6.5lbs.) the optical tube assembly is readily carried and with a compressed length of approximately 50cm (21.7") it is easily transported.

Photography

Being a refractor, it is quick and easy to set up and the low- maintenance, enclosed optics come fully collimated from the factory.  It also performs well as a fixed aperture, 510mm lens for both terrestrial and astrophotography. The "fast" f/5 focal ratio is excellent for capturing lunar and solar eclipses as well as for nature photographs.

 A T-mount thread on the eyepiece holder allows direct attachment of an appropriate T-adapter.

The mount

The intuitive and easy to use AZ3 Alt-Azimuth mount provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes.
