The MM3 80 GA ED is the latest evolution of the MM3 concept pioneered and developed by Opticron with the aim of giving customers the best possible performance in the smallest package at the most affordable price. Constructed from polycarbonate and lightweight alloys, the super-compact optical system creates a body under 30cm/12” long - the size of a 65mm from other brands. As you would expect, images are brighter and sharper giving you more distance and a longer working window for accurate observation. Fully rubber armored, nitrogen waterproof and fitted with dual focusing, the MM3 80 GA ED is compatible with MM3, HR, HDF & SDL eyepieces.
