    Used Orion EON 120mm f/7.5 ED Apochromatic Refractor - Sold

    One look at the EON 120mm Apochromatic Refractor, or through it, and you realize this is one magnificent telescope. It’s a telescope that delivers strikingly detailed views of planetary subjects yet has enough aperture to render revealing images of all the Messier objects and many other deep-space denizens — and we mean visual and photographic images.

    The EON 120ED Refractor Telescope's optics consist of a fully multi-coated, air-spaced 120mm objective doublet lens of exceptional quality, containing one element of FPL-53 extra-low dispersion — "ED" — optical glass. The extra-low dispersion glass virtually eliminates the color fringing around bright objects resulting from chromatic aberration. Images are crisp, sharp, and color-pure, even at magnifications upwards of 250x. The big 120mm refractor telescope objective has a 900mm focal length (f/7.5), a combination that provides excellent high-contrast resolving power, with enough magnification to home in on smaller targets. Baffles inside the optical tube, glare threads in the focuser drawtube, and a retracting lens shade/dew shield eliminate unwanted glare.

    Like all EON telescopes, the 120 Extra-Low Dispersion has a beautifully machined Crayford-type 2" focuser with a removable 1.25" insert, allowing use of either 2" or 1.25" accessories. The gearless Crayford design provides smooth, zero image-shift focusing. The dual-speed focusing knobs have an 11:1 micro-focusing ratio to ensure you achieve the critical focus for your images. The focuser is rotatable 360 degrees, allowing comfortable telescope eyepiece positioning or easy image framing when you’re taking pictures. A dovetail finder scope base comes standard and accommodates any Orion finder telescope or EZ Finder.

    The Orion EON 120 ED Apochromatic Refractor Telescope comes with two hinged tube rings and a dovetail mounting plate. Just add your favorite telescope mount and you’re ready for astronomical adventure! Also included are an aluminum objective lens cap and a sturdy, aluminum-clad carrying case with custom foam interior and carrying handle.
