The Evostar 72 ED is a wide-field telescope offering bright, wide swaths of 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 can be used as an astrograph for sky photography. As a terrestrial spotting scope or telephoto lens, the Evostar 72 ED’s performance is absolutely superb. Ultra high contrast allows the subtlest of details to be easily scrutinized under conditions of good seeing. The petite silhouette of the Black Diamond 72 ED makes for an excellent compact, highly portable telescope that travels light and fits in a small space. At about 50-power structural detail becomes apparent in our solar system’s gas giants like Saturn and Jupiter. The Moon also exhibits striking crater detail along the lunar terminator.
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.
The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
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.
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.
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 Evostar 72 ED Hardware cast-aluminium, painted white.
Evostar 72 ED is supplied with 2” Dual Speed Crayford Focusers and quality foam-lined aluminium carrying cases as standard equipment.
