USED - SpaceCat 51mm f/4.9 APO

USED GEAR INFORMATION This scope is in great condition. The optics appear clean and there are little-to-no cosmetic imperfections on the body of the telescope. This is the first generation of Red / Space cat from William optics, so it uses the helical focuser. Includes soft padded bag with fitted foam for transport. Description From the beginning, the goal was to create the best possible design for an affordable, small, lightweight, and fast Apochromatic refractor for astrophotography needs. The unique optical design includes the highest quality glass for the best possible color correction and flat-field. The result is a 51mm Objective lens, in a sleek Petzval design, for a full frame flat field image. The optical quality provides for exceptional performance at a fast focal ratio of f/4.9.
