Telescope 120ED Black Diamond 120/900 HEQ5 PRO DS GOTO SkyWatcher

Telescope 120ED Black Diamond 120/900 HEQ5 PRO DS GOTO SkyWatcher

Sky-Watcher has just informed us of a change in the upcoming deliveries of EQ6-R and HEQ5 mounts, they will be delivered without the Go-To hand controller. To replace this controller, Sky-Watcher will provide a WiFi adapter that will allow the mount to be controlled directly with a smartphone or tablet (control from the free SynScan app with the same functions as the handheld controller).

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. 

MOUNT FEATURES

Sky-Watcher SynScan mounts have been designed for use by novices and experts alike. These mounts provide extremely high precision tracking and have built in autoguider ports. This heavy-duty HEQ5 Pro mount is a smaller version of the sturdy EQ6 Pro mount. It is specially designed for observers who need the steadiness of the EQ6 Pro mount but finds the EQ6 Pro mount too physically demanding. 

For novice users the user-friendly menu allows automatic slewing to 42900+ objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The SynScan Hand Control also has the ability to connect to a computer via an 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 HEQ5 PRO Mounts, They also come with features that advanced astronomers can appreciate.
