Stubble Jumper ... The last 42mm scope I owned was a Swarovski 1.5x6x42 30mm scope... I remember it as being a very good low light scope just wanted to be sure a 1" 42mm would do the trick and I guess it does based on your feedback. 50mm Leupolds are pretty much useless in low light conditions , having used their scopes for awhile I still don't know why they ever brought that size objective out.
