Re: 56MM OBJECTIVE SCOPE ON MEDIUM RINGS? YUP!!!!!
When is a dozen eggs not a dozen?
Answer; When you have cut off part of the carton.
In this case a 56 mm is not a 56 mm. It is probably only about effectively about 53mm
To get more light into the tube you must have a larger area on the objective or else better coatings and glass. Cutting off the bottoom of the scope reduces the surface area of incident light.
