Oh cripes, now Dan is going to give me grief for revealing how it works.
I ran some numbers for grins.
Here are 3 standard objective sizes that you find on LR scopes. I calculated the diameter needed to reduce by 1 EV, 2 EV and 3 EV: Sizes are all in millimeter:
Obj at 60: 42, 30, 21
Obj at 56: 40, 28, 20
Obj at 52: 37, 26, 18
I'm thinking that any more than 3 EV it will be too dark. I'm even thinking that 2EVs is a lot, except probably on very bright days. I'm also not sure if half-EVs are needed.
