Unlike most ED triplets which are made with just one ED glass element, this beautifully crafted apochromatic refractor stands above ordinary triplets since it features one element of FPL-53 ED glass and one element of FPL-51 ED glass. With its two fluoro-crown ED glass elements and fully multi-coated optics, the Orion EON 85mm ED-X2 refractor provides superior correction of chromatic and spherical aberrations. By suppressing these aberrations so effectively, this triplet "apo" telescope produces impeccable visual views and razor-sharp astrophotos without any fringing or loss of clarity. 

The 85mm EON ED-X2 refractor measures 560mm in focal length with a fast f/6.6 focal ratio which is excellent for wide-field visual and photographic use. Multiple internal baffles prevent off-axis reflections for excellent contrast, while a retractable lens shade helps eliminate glare and dew buildup. With gloss-black machined construction, and attractive satin-red features and accessories, the Orion EON 85mm ED-X2 telescope is a truly gorgeous astronomy instrument. 

This beautiful refractor telescope sports a hybrid-drive 2" rack & pinion focuser which can support imaging gear trains weighing up to 17.6 lbs., and features dual-speed (11:1) controls to easily fine-tune focus. You can rotate the focuser 360° to optimize imaging or observing convenience. The focuser permits 60mm of backfocus travel, and has a built-in focus lock knob. A step-down 1.25" adapter makes the EON 85mm ED-X2 compatible with either 2" or 1.25" size accessories.   

The Orion EON 85mm ED-X2 f/6.6 Triplet Apo Refractor comes with a thread-on objective lens cover, two heavy-duty machined tube rings, a sturdy machined dovetail bar for easy mount attachment, and a dovetail finder scope base (installation required). An included hard carry case with a custom die-cut foam insert ensures safe transport and convenient storage.
