Opticron MM4 GA ED Fieldscope Kits
Opticron MM4 77mm Fieldscope Kits s are available in angled or straight composite polycarbonate/metal alloy bodies with rubber armoring and either HDF T or SDLv2 zoom eyepieces. HDF T eyepieces are the more economical of the two, while SDLv2 eyepieces use better glass and coatings.
