I have the MM3 50mm HD and the MM4 60mm Opticron scopes and am considering adding the MM4 77mm.
I’d like to understand the magnification of the various eyepieces available to me. Some are clear and easily found, such as the SDL2 (40936) and SDL3 (41270) where I understand the magnification would be 18-54x. Others such as the 40810, 40831 and the 40858 do not appear to be well documented!
Thank you.
