With its exceptional 1217mm focal length on a 156mm aperture and 44.4mm image circle suitable for full-frame camera sensors, the scope includes a precision 3.5-inch Feather Touch dual-speed focuser, integrated Bahtinov mask for precise focusing, and robust CNC-machined construction with cradle-style mounting in distinctive red anodizing.
