Orion EON 130mm ED Triplet Apochromatic Refractor

The EON 130 mm (5.12-Inch) Aperture Triplet ED Apochromatic Refractor Telescope by Orion is an exquisite telescope that features premium optical performance and a high-end fit and finish at a price that's thousands less than that of similar-sized Apochromatic Telescopes.

The Optics consist of a three-element, air-spaced lens assembly of 130 mm (5.1-inch) aperture, with one element crafted from FK-61 ED glass for superb color correction and sharpness. The 910 mm focal length makes the EON 130 mm Triplet a wonderfully versatile telescope for both deep-sky and solar system imaging or stargazing. All air-to-glass lens surfaces bear anti-reflection multi-coatings for superior light transmission. Contrast is equally rich thanks to blackened lens edges and two internal knife-edge baffles that prevent off-axis reflections.

The back end of the EON 130 mm Triplet ED has a heavy-duty 3-inch dual-speed Crayford focuser with precise 11:1 fine focus control. The focuser features an Orion finder scope base for attachment of any reflex sight or finder scope with a Vixen style shoe. The big focuser's 3-inch drawtube sports an engraved millimeter scale to aid in focus point repeatability, and features a focus-lock. Both the 2-inch accessory collar on the focuser drawtube and the 1.25-inch adapter feature non-marring brass compression rings.

The EON 130 mm Triplet comes with two substantial, split-clamp tube rings; a 9.75-inch long narrow, Vixen-style dovetail mounting plate. It also comes with a triple-latch hard case with custom-fit foam interior. The hinged tube rings have multiple 1/4-inch by 20 threaded sockets for attachment of mounting plates or other accessories.
