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 gloss-black machined construction, and attractive satin-red features and accessories, the Orion EON 85mm ED-X2 telescope is a truly gorgeous astronomy instrument.

Triplet objective lens with two elements of ED glass for exceptional performance.

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.

Dial-in fine details with the precision dual-speed hybrid-drive focuser.

This beautiful 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 allows use of both 2" and 1.25" size accessories.

An ideal wide-field imaging telescope for discerning astrophotographers and observers.

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. Weighing just 9.25 lbs., the lightweight EON 85mm ED-X2 doesn't require a gigantic mount for stable support, and makes a great addition to any astrophotography setup.

Everything fits nicely in the included hard case for safe storage and transport.

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 of the telescope and all included accessories.
