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. The Orion EON 85mm ED-X2 refractor provides superior correction of chromatic and spherical aberrations, delivering impeccable visual views and razor-sharp astrophotos without any color fringing or loss of clarity.

The EON 104mm ED-X2 sports a big, 2.7" hybrid-drive rack & pinion focuser features dual-speed (11:1) controls to easily fine-tune focus, and can support imaging gear trains weighing up to 17.6 lbs. You can rotate the focuser 360° to optimize imaging or observing convenience. The focuser has a built-in focus lock knob, and a step-down 1.25" adapter makes the EON 104mm ED-X2 compatible with either 2" or 1.25" size accessories.

The 104mm EON ED-X2 refractor measures 650mm in focal length with a fast f/6.25 focal ratio for great wide-field performance. Multiple internal baffles prevent off-axis reflections for excellent contrast, while a retractable lens shade helps eliminate glare and dew buildup. Weighing in at 14.6 lbs. with all included accessories installed, the lightweight EON 104mm ED-X2 matches well with many medium-size mounts for astrophotographic or observational performance.

The Orion EON 104mm ED-X2 f/6.25 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.

This exceptional refractor will satisfy even the most demanding astrophotographers and observers. With gloss-black machined construction, and attractive satin-red features and accessories, the Orion EON 104mm ED-X2 telescope is a truly gorgeous astronomy instrument.
