With two ED glass elements for remarkable true-color performance, the Orion EON 104mm f/6.25 ED-X2 Triplet is certain to satisfy your "apo" appetite. Even the most demanding astrophotographers and observers will be thoroughly impressed by this gorgeous tele. Unlike most ED triplets which feature just one ED glass element, this beautifully crafted apochromatic refractor stands above ordinary triplets by having one element of FPL-53 ED glass and one element of FPL-51 ED glass in its objective lens assembly. With two fluoro-crown ED glass elements and fully multi-coated optics, the Orion EON 104mm ED-X2 refractor provides superior correction of chromatic and spherical aberrations. By suppressing these aberrations so effectively, this triplet "apo" tele produces impeccable visual views and razor-sharp astrophotos without any fringing or loss of clarity. 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. The EON 104mm ED-X2 sports a big, 2.7 inch hybrid-drive 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 has a built-in focus lock knob to enhance imaging convenience. 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 attachment, and a dovetail finder base (installation required). An included hard carry case with a custom die-cut foam insert ensures safe transport and convenient storage. Weighing in at 14.6 lbs., the EON 104mm ED-X2 matches well with many medium-size s.
