When we introduced the 80mm ED refractor a few years ago, it became an instant hit, especially with astrophotographers. With the Orion EON 80mm Extra-Low Dispersion Apochromatic Refractor Telescope, we've incorporated faster optics and all-machined, premium mechanics to present what we believe is an even more desirable telescope for the serious celestial imager, or for the visual observer who wants a compact telescope of uncompromising quality.

The EON 80ED is really an imager's dream telescope. The 500mm focal length yields an f-ratio of 6.25, faster than the standard Orion ED80, which is f/7.5. So the EON 80ED Apochromatic Refractor Telescope gives you brighter images, a wider field of view, and allows shorter exposures of deep-sky objects. The 80mm air-spaced doublet lens is crafted with one element of FPL-53 extra-low dispersion, "ED", optical glass, which virtually eliminates the effects of chromatic aberration. All air-to-glass lens surfaces are fully multi-coated for maximum light throughput. Baffles inside the optical tube, glare threads in the focuser drawtube, and a retracting lens shade/dew shield eliminate unwanted glare to deliver crisp, high-contrast images. The extremely portable EON 80ED measures just 15.5" long with the lens shade retracted, making it nice and easy to transport to your favorite dark-sky site for imaging sessions in the included hard carry case.

Like all EON telescopes the Orion EON 80mm Extra-Low Dispersion Apochromatic Refractor Telescope 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 you need for your images. The focuser is rotatable 360 degrees, allowing comfortable 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 telescope has an integrated L-shaped mounting base that fits the dovetail saddle of Orion and Celestron (and some other) telescope mounts. The base also has 1/4"-20 threaded holes to allow attachment to a sturdy field tripod for terrestrial use.

With its grab-and-go portability, apochromatic optics, and gorgeous "fit and finish," the Orion EON 80mm Extra-Low Dispersion Apochromatic Refractor Telescope is one terrific telescope. And with a DSLR or astronomical CCD camera attached, it becomes an astrophotographic sensation. Weighs 6 lbs., 8 oz.
