Orion 80mm (3.15") ED APO Refractor Telescope OTA
Orion 80mm (3.15 inch) ED APO Refractor Telescope OTA
It's a sweet scope 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 CCD imaging.
The Orion ED 80 refractor sports a fully multi-coated 80mm 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 achromats. Images appear more sharply focused and color fringing around bright objects is lessened dramatically.
The objective lens of the Orion 80mm ED is held in a machined, black anodized aluminum cell and shaded by an aluminum dew cap. Internal tube baffles ensure high contrast and prevent ghosting.
The Orion ED80 features a superb, backlash-free 2 inch Crayford-style focuser, which accepts both 2" and 1.25" diagonals. Notice the focus wheels: classy, brushed-aluminum hubs with ridged rubber grip rings. Nice touch. Set the focuser tension or lock it for imaging with the focus lock knob. The molded-in dovetail base accepts the optional Orion finder scope of your choice, and the tube has a built-in 1/4 inch-20 plate.
