TUBE FEATURES
The Black Diamond 80 ED is a modestly wide field telescope that offers wide swaths of bright sky in a single view. It is well suited for wide-field astronomical observation of prominent nebulae, star clusters, and galaxies from a dark sky location, or it can be used as an astrograph for sky photography. As a spot or telephoto scope, the Black Diamond 80 ED's performance is absolutely superb. The ultra-high contrast allows the finest details to be easily examined in good visibility conditions. The small silhouette of the Black Diamond 80 ED makes it an excellent compact and portable telescope that travels light and fits in a small space. At roughly 50 powers, structural detail is evident in the gas giants of our solar system like Saturn and Jupiter. The Moon also exhibits striking crater detail along the lunar terminator.
High transmission metallic lens coatings
Each air-to-glass lens surface has exotic anti-reflective metallic coatings applied to ensure optimum light output close to 99.5%. Sky-Watcher's "High Transmission Metallic Coatings" (MHC) are the best photon rejection coatings in their class.
Optical systems with light deflectors
The objective lens cell has a light deflector to reject stray and out of focus light. The extraction tube is also baffled to ensure optimal contrast. The inside of the tube is flat blackened to help prevent defocused internal light reflections from reaching the focal plane.
Dual speed 2 ”precision Crayford focuser is standard
Optical focusing is achieved by means of a mechanically ultra-smooth 2 ”precision double speed Crayford focuser assembly with no backlash. This focuser offers fine and ultra-fine focus adjustments.
Tube materials
Optical tube material is laminated steel, reflective glossy black powder coated with gold fleck accent. The front and rear cells are cast aluminum painted white or black.
Telescope tube accessory
The optical tube comes with mounting accessories that allow you to securely attach it to any Sky-Watcher mount. Quick release tube rings are supplied with Black Diamond 80 ED Hardware cast aluminum, painted white.
Components included for select models
Black Diamond 80 ED is supplied with 2 ”dual speed Crayford focusers and quality foam lined aluminum carrying cases as standard equipment.
MOUNT FEATURES
SkyWatcher's EQM-35 is the main evolution of the NEQ3-2 small equatorial mount. Although it evolved, the latter suffered from limited astrophotographic use. Sky-Watcher evolves by judiciously using the modularity of its two transportable little sisters, the Star Adventurer and the Star Adventurer Mini, from which it inherits some of its photographic accessories.
The result is a highly modular mount, usable as a classic equatorial mount or as a photographic equatorial mount whose possible configurations are identical to those of the Star Adventurer range. The great advantage is its maximum load capacity of 10 kg that allows you to load optical tubes like the Newton 150/750 or even the Newton 200/1000 in visual use. It can also be loaded with a 150mm Maksutov-Cassegrain or a 120mm telescope. From a photographic point of view, such a load gives a lot of freedom, including the ability to install large professional cameras or telephoto lenses with a long focal length, with careful balance.
To make the head decline detachable, the right riser has undergone impressive design stretch and has grown in diameter and strength, with more massive bearings than the EQ3-2. As a direct result, the drive gear increases from 130 to 180 teeth, which improves tracking accuracy.
The highlight of the EQM-35 is its ability to transform into a photographic equatorial mount. Sky-Watcher engineers had a good idea to keep the possibility of repositioning a conventional declination axis. Once the declination axis has been removed and the alternative Vixen-type female dovetail installed, the same options are available as on Star Adventurer frames: installation of a photographic spherical plate, an autoguide system, an L-mount bracket with or without counterweight bar, etc.
Whatever the configuration, use of the provided polar finder is fully preserved.
The EQM-35 in classic configuration:
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, in the normal way, thanks to a female Vixen dovetail.
The EQM-35 in photo settings:
The original configuration of the EQM-35 is that of a photographic equuatrial mount, like the Star Adventurer mounts, without a declination axis. An alternate female dovetail replaces and attaches, for example, a male dovetail with an optional congressional tilt screw (3/8 "). All Star Adventurer mount accessories are compatible.
Go-To auto-alingning system:
The Sky-Watcher EQM-35 Modular Equatorial Mount is equipped as standard with a Goto automatic aiming system, equipped with an original control box to manage both the classic and photo mount settings. Disassembly of the declination axis, and therefore the motor associated with it, does not impede the monitoring and guidance functions in AD. Of course, in the absence of a Dec motor, Goto pointing is disabled.
In its Goto configuration, the EQM-35 mount is called the EQM-35 Pro.
