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. Package includes matching grey 40mm finder. premium 1.25" diagonal and aluminium case.
It sports a 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 colour fringing around bright objects is lessened dramatically.
The objective lens is held in a machined, black anodized aluminium cell and shaded by an aluminium dew cap. Internal tube baffles ensure high contrast and prevent ghosting.
The ED80 features a superb, backlash-free 2" Crayford-style focuser, which accepts both 2" and 1.25" diagonals. Notice the focus wheels: classy, brushed-aluminium hubs with ridged rubber grip rings. Nice touch. Set the focuser tension or lock it for imaging with the focus lock knob. The moulded-in dovetail base accepts the optional Orion finder scope of your choice. Tube has a built-in 1/4"-20 plate.
At a length of just 24", the ED80 is extremely portable.
