[QUOTE="Gamesniper19, post: 2143284, member: 95013"] I recommend you go hands on with the glass. If you plan on shooting a distance where you have to turn the scope up to it maximum magnification, some scopes can lose a bit of clarity and it may not always be the glass. Here is some science that may help you decide. The human eye can only resolve a minute of angle at 100 yards. For scopes you divide 114.3 (Rayleigh’s constant) by objective to find the highest power that an optic is usable. Going beyond that power only amplifies errors - mirage, heartbeat, wind wiggle, etc... So an 80mm spotting scope’s optimal magnification is 42x. 114.3/80mm = 1.43 seconds, then 60 seconds / 1.43 = 42x So for a scope with a 50 mm objective the max power should be = 26x [/QUOTE]
