Designed and manufactured in Japan, the latest VHD optical system incorporates an FCD 100 glass objective lens element with refractive properties similar to fluorite glass. The result is reduced CA and improved color saturation over standard ED, helping the models deliver a new benchmark in color resolution and contrast.
What makes the MM4 77 exceptional is the package size and weight. The 77 GA VHD/45 fully rubber-shielded GA VHD/45 with SDLv4 18-54x measures only 370 mm/14.6" long and weighs 1519 g/53.6 oz. These figures are similar to those of a 65mm, unable to offer the optical performance of this 80mm device.
Compatible with SDL, HDF, HR and MM3 eyepieces, existing owners can use their eyepieces with the MM4 77 Fieldscopes.
