Product Details

  • If you're seeking a top-of-the-line instrument to advance your capabilities and enjoyment in astrophotography or visual astronomy, the Orion EON 130mm Triplet ED Apochromatic Refractor is the candidate that can deliver. This sophisticated telescope features premium optical performance and a high-end fit and finish at a price that makes it accessible and affordable. This refractor boasts an even more robust focuser with streamlined tube rings and dovetail bar. This is truly an awe-inspiring telescope.

    Front End of the EON 130mm Triplet

    At the front of this refractor, you'll find a 3 element, air-spaced lens assembly of 130mm (5.1") aperture. One element is crafted from FK-61 ED glass, providing exceptional color correction and sharpness. The 910mm focal length makes the EON 130mm Triplet a wonderfully versatile telescope. You can use it for both deep-sky and solar system imaging or stargazing with plenty of image scale for smaller targets and a moderately fast f/7.0 focal ratio. All air-to-glass lens surfaces are thoughtfully manufactured with antireflection multi-coatings for superior light transmission. Contrast is equally rich with help from blackened lens edges and two internal knife-edge baffles that prevent off-axis reflections of incoming light. The EON 130mm Triplet ED Refractor also features an extendable dew shield that helps inhibit dew formation on the lens.

    Back End of the EON 130mm Triplet

    At the back end of this refractor, you'll find a heavy-duty 2.5" dual-speed Rack-and-pinion focuser with precise 10:1 fine focus control. The focuser features an Orion finder scope base for attachment of any Orion reflex sight or finder scope, if desired. The big focuser's 2.5" drawtube is ideal for astrophotography due to its engraved millimeter scale, which aids in focus point repeatability and features a focus-lock thumbscrew. Both the 2" accessory collar on the focuser drawtube and the 1.25" adapter feature non-marring brass compression rings and a robust twist-lock style mechanism to securely clamp down onto the diagonal or camera nosepiece.

    The EON 130mm Triplet comes with two substantial, split-clamp tube rings, an 11.75" long narrow, "Vixen-style" dovetail mounting plate, and an attractive, triple-latch hard case with custom-fit foam interior. The hinged tube rings feature multiple 1/4"-20 threaded sockets for attachment of mounting plates or other accessories. The protective hard case is very portable at just 37" long, making it perfect for star parties that require you to do a little traversing. The EON 130mm fits snugly inside with its dew shield retracted and slip-on lens cover installed.
