SkyWatcher ED Black Diamond ED120 HEQ5 PRO GOTO SkyWatcher ED Refractor Telescope.
The apochromatic ED refractor tubes of theBLACK DIAMOND series from SKYWATCHER represent a range of refracting astronomical telescopes with a fairly well-corrected field and with a highly corrected chromatic aberration. Their low dispersion ED optics allow the light to refract through the lens so that the light beam does not scatter much (does not open up) and therefore the image definition is greatly increased. SKYWATCHER BLACK DIAMOND refractors are constructed with a two-element air-spaced objective lens. The second lens element is constructed with the high quality fluorinated glass FPL-53 (O'HARA version).
The ED optics of the BLACK DIAMOND refractor telescopes are made of SCHOTT glass. This combines the efforts of two market leaders, Synta as a manufacturer of astronomical telescopes and SCHOTT as the world's leading manufacturer of the highest quality optical glass.
Observing with the Black Diamond ED120.
Lucky is the amateur astronomer who is observing a clear night of clear skies and atmospheric stability with a SKYWATCHER Black Diamond ED120mm.
If you aim at the Moon when it is waxing, and focus your observation on the Apennine region for maximum focus, magnificent details of the surrounding peaks, canyons and countless small craters will be revealed. We could say that this is observing the Moon in HD. The gas giant Jupiter shows its equatorial bands in high definition revealing internal and inter-band boundary details. The large red spot is clearly visible in full contrast to the rest of the Jovian landscape. In the case of deep sky nebulae, the SKYWATCHER BLACK DIAMOND ED 120 allows enhanced definition to be seen in the gaseous extensions of the outermost parts. Globular clusters are presented with all their stars resolved as perfect point stars. This is just the beginning of an incredible journey you can take with the SKYWATCHER BLACK DIAMOND ED120.
High Transmission Metallic Coated Lenses
All lenses that are exposed to the open air are coated with an anti-reflective coating to ensure maximum light transmission, achieving a transmission factor of 99.5%. SKYWATCHER's proprietary Metallic High-Transmission Coatings (MHC) is the most refined anti-reflective coating in its class.
Optical system with baffles
The objective lens cell is designed to reject residual light that is not in focus. The tube itself is designed with internal baffles to ensure maximum contrast by eliminating unwanted light. The inside of the tube is also finished in matte black to prevent internal reflections from reaching the focal plane.
2" Precision Crayford Focuser
Focusing can be achieved thanks to the fine, smooth mechanical, backlash-free gearing of the Crayford 2" focuser that is integrated as standard. This precision 2" Crayford is based on a rack and pinion assembly system.
Tube material of construction
The optical tube is manufactured from cast aluminum, painted white or black, for the front and rear cells. The tube itself, the cylindrical part is plated in steel with a glossy black finish with gold highlights.
SkyWatcher offers a simple solution for those users who would like to be able to attach their small telescope to a computerized mount. The SynScan system allows you to locate a specific object and even allows you to travel from one object to another along a tour at the touch of a button.
Key features:
SKYWATCHER telescopes supplied with a German equatorial mount with integrated SynScan system are high quality observing platforms with well thought-out mechanics and electronics.
Motors, crowns and bearings:
The SynScan series SKYWATCHER mounts use DC stepper motors with high torque capacity and microstepping control technology for maximum precision. Bronze crown and worm gear system for precision mechanical incremental movement minimizing gear backlash.
Tracking speeds and modes
The versatility of the SynScan system allows various search and guidance speeds to be selected. The tracking modes are: Lunar, Solar and Sidereal. The mount is compatible with use in both the Northern and Southern hemispheres.
Database
The SynScan computer includes a database of over 40,000 objects in memory. The library includes objects for advanced studies, following the existing catalog system: NGC, IC, Caldwell, Messier and other lists plus 25 user-definable objects (comets, asteroids, etc).
Astrophotography
Astrophotography enthusiasts will greatly appreciate the presence of the AUTO-GUIDER port that allows autoguider functions to be performed through a PC. The SynScan firmware includes the SynScangramming algorithm for periodic error correction (this error is natural and inherent to all corona-bisenfin systems). In addition, this algorithm can be complemented with the Backlash compensation function (technical term to describe gear backlash) for both AR and DEC. In this way it is possible to have uniform GOTO's and tracking.
