About the Sky-Watcher BK 705AZ3 - 70mm Refractor Telescope w/ AltAz Mount...

The 70mm (2.8") f/5 and 80mm (3.1") Sky-Watcher Telescope are two-element, air-spaced, fully multi- coated objective, refractors. The 80mm f5 is a well- proven performer which gives "rich- field" views of star fields, clusters, nebulae, bright galaxies, planets, the Moon and (with correct filtering or by projection) the Sun, as well as excellent terrestrial views. Both Sky-Watcher Telescopes give images which are crisp and with very little chromatic aberration.

 

One of the greatest assets of the solidly built Sky-Watcher BK 705AZ3 - 70mm Refractor Telescope w/ AltAz Mount is portability. The light-weight optical tubes (1.25kg; 2.8lbs for the 70mm and 1.5kg; 3.3lbs for the 80mm), and the compressed lengths of about 380mm (15") and 480mm (18") make them "take it with me" Sky-Watcher Telescopes. Their optical tubes can be adapted to fit into an airline carry-on bag, or into a hiker'''s backpack. Whether they are to be used as a beginner'''s Sky-Watcher Telescope, a "rich-field", a backup, a guide scope or a travelling telescope, the very reasonable prices make them choices to seriously consider.

 

The Sky-Watcher BK 705AZ3 - 70mm Refractor Telescope w/ AltAz Mount is quick and easy to set up and the low- maintenance, enclosed Sky-Watcher Telescope optics come fully collimated from the factory. Alignment of the finderscope and polar alignment of the optional equatorial Sky-Watcher Mount are all that are needed to start viewing. The optical tube assemblies are 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 the supplied aluminum alt-azimuth Sky-Watcher Mount or a photographic tripod is quick and simple with the supplied "multi-function mount plate".

 

Both Sky-Watcher Telescopes perform well as a fixed aperture lenses for both astrophotography and terrestrial photography. The "fast" focal ratios, combined with today'''s high speed films, makes the Sky-Watcher BK 705AZ3 - 70mm Refractor Telescope w/ AltAz Mount useful for capturing lunar and solar eclipses as well as nature photographs. With a suitable T-adapter, a camera can be connected directly to the T-mount thread on the eyepiece holder and a supplied 60mm (2.4") extension tube allows closer focusing for terrestrial photography.

 

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!
