This Black Diamond Evostar 120ED uses a 120 mm ED doublet objective and 900 mm focal length at f/7.5. The unobstructed refractor design is suitable for visual astronomy and, with the appropriate imaging accessories, astrophotography.
Focusing and visual accessories
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.
Optics and installation
MHTC optical coatings support light transmission. The manufacturer lists an OTA weight of 5.13 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.
Global legacy ED model and listed accessory specification used. The 120ED table repeats an implausible 100 × 620 mm tube dimension from the smaller model; that dimension is omitted.
