BK1206AZ3 (SHORT TUBE)

This SkyWatcher 120mm (4") f/5 telescope is a two-element, air-spaced, fully multi-coated objective, achromatic refractor, which can give exciting "rich field" astronomical views. Skywatcher 120mm BK120 telescopes are 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 travelling telescope for a more advanced observer. Skywatcher 120mm BK120 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. Skywatcher 120mm BK120 telescopes are 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.

This Skywatcher 120mm BK120 telescopes are also performs well as a fixed aperture, 510mm lens for both terrestrial and astro photography. The Skywatcher "fast" f/5 focal ratio, combined with today's high speed films, is excellent for capturing lunar and solar eclipses as well as for nature photographs. A solid, equatorial mount and a method of guiding is required for longer exposure astrophotography. A T-mount thread on the eyepiece holder allows direct attachment of an appropriate T-adapter (readily available through camera shops for a specific SLR) and the optional60mm (2.5") extension tube gives closer focus-sing for terrestrial photography.
