For the dedicated visual observer or astrophotographer seeking a top-of-the-line instrument, the Orion EON 130mm Triplet ED Apochromatic Refractor should be on your short list of candidates. This exquisite telescope features premium optical performance and a high-end fit and finish. From front to back, this is truly an awe-inspiring refractor. At the front end, you’ll find a three-element, air-spaced lens assembly of 130mm (5.1 inch) aperture, with one element of FPL-51 ED glass for superb color correction and sharpness. The EON 130mm Triplet is a wonderfully versatile telescope for both deep-sky and solar system imaging or stargazing since it has plenty of image scale for smaller targets and a moderately fast f/7.0 focal ratio. All air-to-glass lens surfaces bear anti-reflection multi-coatings for superior light transmission. Contrast is equally rich thanks to a retractable glare-blocking dew shield, blackened lens edges and five internal knife-edge baffles that prevent off-axis reflections of incoming light. At the back end of the EON 130mm Triplet ED, you’ll find a heavy-duty, 3 inch, dual-speed, rotatable Crayford focuser with precise 11:1 fine-focus control. The big 3 inch drawtube sports an engraved millimeter scale to aid in focus point repeatability. The EON 130mm Triplet comes with two substantial, split-clamp tube rings and a hard case with custom foam interior. The tube rings feature multiple 1/4 inch-20 threaded sockets for attachment of mounting plates or other accessories.
