This Black Diamond Evostar 80ED uses a 80 mm ED doublet objective and 600 mm focal length at f/7.5. The unobstructed refractor design is suitable for visual astronomy and, with the appropriate imaging accessories, astrophotography.
A dual-speed 2-inch Crayford focuser provides fine adjustment for an eyepiece or camera. Sky-Watcher lists an 8×50 finder, a 2-inch 90° dielectric diagonal with a 1.25-inch adapter, and a 2-inch LET 28 mm eyepiece for this legacy model.
MHTC optical coatings support light transmission. The manufacturer lists an OTA weight of 2.47 kg; a suitable equatorial mount must also accommodate the camera, diagonal and other fitted equipment. A matching imaging corrector is selected for this ED generation rather than for the newer EDX tube.
