Re: spotting scopes?
Yeah, mfp28 called it. The one in his picture is 20 power at the weak end, and adjustable to 60 power at the high end. The "x60" refers to the diameter of the "looking out of" lens (as opposed to the "looking into" lens), in millimeters.
The bigger the last number is, the larger diameter, so the more light comes in, so the easier it is to see little stuff and/or far away stuff. Like with a rifle scope. Used to was the standard scope was "4x32" or "3-9x32". 32mm lens. Now, pretty much, the standard is 40mm, and many are 50mm, and I think I've seen some 60mm. They let in more light, so you can see better.
The first two numbers are the magnification. 20-60 means something looks from 20 times closer to 60 times closer.
What you need depends on how far you are shooting, how big a bullet you are shooting, and, of course, how deep your pockets are. Let's assume, for example, that you are shooting a 22, and you can clearly see 22 bulletholes at 20 feet. You are shooting at 100 yards. 100 yards is 15 times as far away as 20 feet. So for that use, a 15-power scope would be strong enough. Shooting at 200? Now you need a 30-power scope. Can only see the holes at ten feet, and you're shooting at 200 yards? You need a 60-power scope.
