More Information

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 armoured, nitrogen waterproof and fitted with dual focusing, the MM3 80 GA ED is compatible with MM3, HR, HDF & SDL eyepieces.
