Product Description
Featuring two ED glass elements for remarkable true-color performance, the Orion EON 85mm ED-X2 Triplet Apo Refractor heralds a new era (or should we say an “eon”?) of optical excellence. This exceptional refractor will satisfy even the most demanding astrophotographers and observers.
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.
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.
The EON 85mm ED-X2 sports a hybrid-drive 2″ rack and 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-deg 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 inch adapter is included.
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.
