I have a nice Leupold Golden Ring 15-30 X 50mm spotting scope that does well at up to 50 yards, but I have trouble seeing my 25 caliber holes at 100. It is light, which is one of my criteria, and does a creditable job for birding. but, my aging eyes seem to need more help nowadays.
I am thinking of buying another scope, perhaps with a 60 or 65 mm objective, which will admit more light and transmit more detail. The figures say that a 60mm objective will transmit 1.25 times the light and detail, and a 65 mm transmits about 2.25 times, depending upon coatings, etc. It looks like the 65m wins, and should be good compromise between compactness and weight.
But, High-power shooters have been using the heavier, but relatively inexpen$ive Konus 20-60 X 80 scopes, or Celestron scopes for years, with reportedly good results. They don't carry their scopes much, though.
So, has anyone had experience with going from a 50mm objective scope to a 60 or 65, and did the additional area of the objective make any difference in clarity and sharpness? How about from ~50 mm to 80?
Any help/recommendations will be appreciated.
Thanx
