So, regarding diameters, can i assume the apertures get worse as the diameter gets larger ?
EG .. 90mm Mak Cass would have wider aperture than 130mm Mak Cass. In which case, for those interesetd in trying out these scopes, it may be sensible in sticking to the bottom end range of the available diameters, like 90mm ?
