Sky-Watcher Pro 80 ED APO Refractor OTA
The Sky Watcher ED80 is a modestly 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, theSkywatcher ED80’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 Sky Watcher Pro ED80 makes for an excellent compact, portable telescope that travels light and fits 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.
The Skywatcher Black Diamond ED80 benefits from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation, and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers. 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” Crayford rack & pinion 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 Black Diamond ED80 are cast-aluminum, painted white. The Sky Watcher Black Diamond ED80 is supplied with backlash-free 2” Crayford focusers and quality foam-lined metal carrying cases as standard equipment. Black Diamond ED80 is also supplied with 8x50mm viewfinder with bracket; 2” dielectric diagonal; two 1.25” LE (Long Eye Relief) eyepieces (LE20mm and LE5mm); 1.25” focuser adaptor; and tube ring attachment hardware for mounting to any Sky-Watcher, or other compatible mounts.

Overall, a good scope. Great views. The focuser...well,not too good. With a 2 EP, any angle above 30 degrees, it doesn't want to move unless you nudge the diagonal first. Playing with the tension only works for so long. You can remove it and make sure the flat part on the tube(where the shaft rotates and moves it is flat by using a stone,(google it. I will do that but honestly, should not have to do so. Will probably end up upgrading the focuser to something that can handle more than 1.5 lbs. Otherwise, the scope is a good buy.

Product QuestionsQuestion by: Lee on Dec 25, 2016 2:18:00 PMThe reducer/flattener designed to work with this scope is the SW-S20200 0.85x Sky-Watcher reducer. https://www.optcorp.com/sky-watcher-focal-reducer-corrector-for-pro-ed80-s20200.html. This reducer does end in an M48 thread, so you will need an appropriate M48 wide T ring.Answer by: Chris Hendren (Admin) on Dec 27, 2016 2:56:00 PMQuestion by: Paul on Jun 12, 2016 12:02:00 PMHi Paul,
No, they are optional. In fact, it would also be a really good idea to consider purchasing a field-flattener, as well, unless you plan on using a relatively small-format camera. The Pro 80ED has great color-correction, but with it not using an integrated flattener, you will notice field-curvature. Thankfully, Skywatcher offers a matched flattener: https://www.optcorp.com/sky-watcher-focal-reducer-corrector-for-pro-ed80-s20200.html, which will doa fantastic job of correcting the field for even 35mm-film format DSLR/CCD cameras.Answer by: Eric Blackhurst (Admin) on Jun 17, 2016 6:12:00 PMWill this scope fit on a Celestron Advanced VX mount straight out of the box or will I need an adapter?Question by: Robert Stein on Mar 11, 2015 11:15:00 AMNot without an additional accessory for the tripod like the OS-DM. The tripod head would also have to be rated for about 2x what the scope weighs (~7 lbs, so rated for 14+ lbs) or it might slip backwards when the scope is pointed high in the sky. A small telescope mount would be much sturdier.Answer by: Chris Hendren on Mar 16, 2015 3:30:00 PM
