About the Sky-Watcher BK 1025 AZ - 102mm Refractor Telescope w/ AZ SynScan GPS...
This 102mm (4") f/5 Sky-Watcher 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. The Sky-Watcher BK 1025 AZ - 102mm Refractor Telescope w/ AZ SynScan GPS is also a fine terrestrial telescope. Crisp images at a reasonable price make it an excellent beginner''s "first telescope", or a great travelling Sky-Watcher 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.
Being a refractor, the Sky-Watcher BK 1025 AZ - 102mm Refractor Telescope w/ AZ SynScan GPS is quick and easy to set up and the low- maintenance, enclosed optics come fully collimated from the factory. The optical tube assembly comes with "tube-mounting rings". These hinge open to allow easy installation of the Sky-Watcher Telescope optical tube and the locks can be loosened during use to allow tube rotation and balancing.
The Sky-Watcher BK 1025 AZ - 102mm Refractor Telescope w/ AZ SynScan GPS also performs well as a fixed aperture, 510mm lens for both terrestrial and astrophotography. The "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 the Sky-Watcher Telescope is required for longer exposure astrophotography. A T-mount thread on the Sky-Watcher Telescope Eyepieces holder allows direct attachment of an appropriate T-adapter (readily available through camera shops for a specific SLR) and the optional 60mm (2.5") extension tube gives closer focusing for terrestrial photography.
The exciting new Sky-Watcher SynScan Alt-Azimuth GoTo Mount - part of the Sky-Watcher BK 1025 AZ - 102mm Refractor Telescope w/ AZ SynScan GPS package - is a precision engineered instrument that will allow you to easily find and enjoy viewing night sky treasures, such as Planets, Nebulae, Star Clusters, Galaxies and much more. The SynScan AZ hand control allows you point your Sky-Watcher Telescope at a specific object, or even tour the night sky at the touch of a button! The user-friendly menu system allows automatic slewing to over 42,900+ objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions.
Don'''t forget, we carry plenty of Sky-Watcher Accessories, too! Look for Sky-Watcher Telescope Eyepieces and Sky-Watcher Telescope Filters for visual observers! Astrophotography buffs will appreciate Sky-Watcher Photo Adapters and the Sky-Watcher SynGuider!
