ED80 f7.5 doublet with one element of FLP53 glass
Interested in owning a premium apochromatic refractor without having to take out a second mortgage? Then check out our amazingly affordable Orion ED80 80mm extra-low dispersion Apochromatic Refractor Telescope optical tube. This is one sweet telescope for astrophotography or visual use.
It's a sweet telescope all right. With a focal length of 600mm (f/7.5), the "ED80" is wonderfully suited for visual applications on both solar system and deep-sky objects as well as for prime-focus astrophotography and charge coupled device or, "CCD" imaging.
The ED80 refractor telescope sports a multi-coated 80mm aperture objective lens doublet, one element of which is crafted from Extra-Low Dispersion, or "ED" optical glass. This high-grade glass greatly reduces the chromatic aberration inherent in standard achromatic refractor telescopes. Images and views appear more sharply focused and color fringing around bright objects is lessened dramatically. The refractor objective lens is held in a machined, black anodized aluminum cell and shaded by an aluminum dew cap. Precisely positioned internal tube baffles ensure high contrast and prevent ghosting.
The Orion ED80 refractor features a superb, backlash-free 2" Crayford-style focuser, rings and vixen style dovetail
This scope is in great condition and comes with Skywatcher ED80 metal case for transporting.
Selling due to upgrade as been bitten by the deep space astrophotography.
Selling for $650 plus postage
Please note sale is for ota and finderscope / rings and dovetail only (guidescope/ eaf/ cameras / dew heaters / mount are not included in sale)
