Refractor Telescope Skywatcher Black Diamond 80ED with EQM-35 PRO Goto mount
The apochromatic ED refractor tubes of theBLACK DIAMONDseries 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 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.

The new EQM-35 mount is the further evolution of the small NEQ3-2 equatorial mount. Although very practical, the NEQ3-2 is not optimal for astrophotographic use. Therefore, Sky-Watcher finally presents this new version with the modularity of the Star Adventurer series, which already inherits the distinctly astrophotographic functionality.
The result is a very versatile and highly modular mount, it is a conventional equatorial mount whose configurations are identical to those of the Star Aventurer range. The great advantage is its maximum load capacity of 10 kg, which allows it to accept Newton Newton 200/1000 or 150/750 optical tubes for visual use, or a 120 mm or 150 mm Maksutov-Cassegrain. From a photographic point of view, such a load capacity gives a lot of freedom, allowing the installation of large professional cameras or long focal length telephoto lenses, always keeping a very good balance.
The straight ascender shaft has undergone an impressive redesign and has grown in diameter and strength, with more massive bearings than on the EQ3-2. As a direct result, the drive gear increases from 130 to 180 teeth, greatly improving tracking accuracy.
The highlight of the EQM-35 mount is its ability to transform into an astrophoto mount. Once the declination head is removed, we get the same options offered by the Star Adventurer mounts: ball joint, guiding system, L-bracket with or without counterweight bar...
Whatever the configuration, the functionality of the polar finder provided is fully preserved.
The classic configuration of the EQM-35 is that of a standard equatorial mount, equipped with its two axes of motion, right ascension and declination. It can accept all optical tubes, naturally, thanks to a female dovetail type Vixen.
The Sky-Watcher EQM-35 Pro Goto modular equatorial mount is equipped as standard with a Goto automatic aiming system, it carries an original control box to manage the mount settings for classical and astrophotographic configuration. Disassembling the declination axis, and therefore the motor associated with it, does not impede the tracking and guiding functions in AR. Of course, in the absence of a Dec motor, Goto pointing is disabled. The SynScan control knob completes the set.
