Telescope Black Diamond ED 120/900 AZ-EQ6 PRO DS GOTO SkyWatcher

PRODUCT FEATURES

Observing with Black Diamond 120 ED

The additional aperture of this telescope provides a dramatic increase in resolution and a heightened sense of seeing lunar and planetary surface phenomenon in seemingly 3D-like high-definition. Tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pinpoints, 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.

Metallic High-Transmission Lens Coatings 

Each air-to-glass 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 objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to ensure 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 as Standard

Optical focus 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.

Tube Materials

The 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 ED120 SCHOTT are cast aluminum, painted white.

Included Components for Selected Models

Black Diamond 120 ED SCHOTT is supplied with backlash-free 2” Dual Speed Crayford Focusers and quality foam-lined Aluminum carrying cases as standard equipment. 

FEATURES MOUNT

The Sky-Watcher AZ-EQ6 SynScan mount gives optimal stability and pointing accuracy for a wide variety of heavy professional photo and video equipment. It is a hybrid mount with alt-azimuth capability for general use and equatorial capability for astrophotography use. Supplied with a SynScan handset with dual AZ/EQ firmware, it can automatically find and track 42,900+ celestial objects with its database.

AZ-EQ6 SynScan is capable of carrying heavy-duty photographic equipment for professional shooting and video recording. It is a very efficient transportable mount weighing only 15 kg, for a load capacity of 20 kg (counterweight excluded).

Freedom Find™ - tracking made easy!

With the patented Freedom Find (dual-encoder) technology which allows the telescope to be moved manually or electronically in either axis without losing its alignment or positional information. After moving to a new object the telescope will automatically begin to track the new object accurately. No re-setup is required in one observing session.

German Equatorial / Alt-Az dual mode

Permanent periodic error correction(PPEC). PPEC can be trained with Autoguider or PC.

Belt drive - Super smooth PE curve. Low backlash, silent slewing.
