About the Sky-Watcher BK 1021 AZ3 Black Diamond 102mm Refractor Telescope...
The additional aperture of the Sky-Watcher BK 1021 Black Diamond 102mm Refractor Telescope provides a dramatic increase in resolution and a heightened sense of seeing lunar and planetary surface phenomenon in seemingly 3D-like high-definition. In this Sky-Watcher Telescope, tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pin points, star upon thousands of stars deep into the objects core. In Deep-space, rich aggregates of stars within Galaxies, Nebulas, and open clusters appear brilliant contrasted against a very dark velvet black background. The wispy, delicate, featherlike structure of dust lanes and extension of glowing gasses can be seen reaching out far beyond the object''s core.
Each air-to-glass lens surface on this Sky-Watcher Telescope has exotic anti-reflection metallic coatings applied to ensure optimum light through-put of approaching 99.5%. The proprietary Sky-Watcher Metallic High-Transmission Coatings (MHC) are the finest photon anti-rejection coatings in their class. The objective lens cell of the Sky-Watcher BK 1021 Black Diamond 102mm Refractor Telescope is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
Optical focus of the Sky-Watcher BK 1021 Black Diamond 102mm Refractor Telescope is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Dual Speed Crayford Focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments. The Sky-Watcher Telescope optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white, or black. Combine with a tracking Sky-Watcher Mount for excellence in astrophotography.
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!
