MM4 77 VHD Fieldscopes are the latest evolution of the MM4 concept pioneered and developed by us to meet demand for high performance lightweight space saving equipment.
Designed & manufactured in Japan, the latest VHD optical system incorporates an FCD 100 glass objective lens element with refractive properties similar to Fluorite crystal. The result is reduced CA and improved color saturation over standard ED helping the models deliver a new benchmark for resolution and color contrast.
What makes the MM4 77 exceptional is the size and weight of the package. The fully rubber armored 77 GA VHD is 315mm/12.4” long and weighs 1248g/44oz. These figures read like a 65mm which is unable to deliver the optical performance of this 80mm class device.
Compatible with SDL, HDF, HR and MM3 eyepieces, existing owners can use their eyepieces with MM4 77 Fieldscopes.
