The EON 120ED'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 ED glass virtually eliminates the color fringing around bright objects resulting from chromatic aberration. Images are crisp, sharp, and color-pure, even at high magnification. The big 120mm objective has a 900mm focal length (f/7.5). 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 120ED 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. 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 scope or EZ Finder. The EON 120ED comes with two hinged tube rings and a dovetail mounting plate. Also included are an aluminum objective lens cap and a sturdy, aluminum-clad carrying case with custom foam interior and carrying handle. Weighs 14 lbs., 9 oz. One-year limited warranty.
