About the Sky-Watcher Black Diamond 120ED - BK 120ED Refractor Telescope w/ EQ6 SynScan GPS...
Fortunate indeed is the amateur astronomer with a SkyWatcher Black Diamond 120 ED Refractor Telescope! The additional aperture of this Sky-Watcher Telescope provides a dramatic increase in resolution and a heightened sense of seeing lunar and planetary surface phenomenon in seemingly 3D-like high-definition.
With a SkyWatcher Black Diamond 120 ED Refractor Telescope w/ EQ6 SynScan GPS, 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 object''s core. In Deep-space, rich aggregates of stars within Galaxies, Nebulas, and open clusters appear in the Sky-Watcher Telescope to be brilliantly 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 horizons.
For novice users the user-friendly menu on-board the SkyWatcher Black Diamond 120ED - BK 120ED Refractor Telescope w/ EQ6 SynScan GPS allows automatic slewing to over 13,400 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The Sky-Watcher Telescope SynScan Hand Control also has the ability to connect to a computer via a RS-232 cable. Once the connection has been established between the computer and SynScan Hand Control, many commercially available planetarium software programs can be used to control the EQ6 PRO Sky-Watcher Mounts, They also come with features that advanced astronomers can appreciate.
Metallic High-Transmission Lens Coatings - Each air-to-glass Sky-Watcher Telescope lens surface 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.
Light-Baffled Optical Systems - The Sky-Watcher Telescope objective lens cell 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.
Precision 2" Dual Speed Crayford Focuser is Standard - Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Dual Speed Crayford Focuser-assembly. This Sky-Watcher Telescope focuser offers fine and ultra-fine focusing adjustments.
Tube Materials - 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.
Telescope Tube Attachment Hardware - The optical tube comes with attachment hardware that allows it to be securely fastened to any Sky-Watcher Mount. The quick-release tube rings provided with Black Diamond 120 ED are cast-aluminium, painted white.
Included Components for Selected Models - Black Diamond 120 ED is supplied with 2" Dual Speed Crayford Focusers and quality foam-lined aluminium Sky-Watcher Telescope carrying cases as standard equipment.
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!
