I agree it could make for convenient setting circles on a scope. However, it may be susceptible to any magnetic steel parts on the mount or scope. Fortunately, most metal scope parts are non-magnetic stainless steel or aluminum.

I think the killer application of that technology is in a pair of good binoculars. You can scan the sky and when you see an interesting smudge, press a button to snap the coordinates, and then go there with your big scope.
