Nice job on the elk!
I'm a little confused on the scope problem......Was the scope not bright enough, was the power to high and the FOV not big enough, was it to heavy? What was the problem with it?
I don't have the 5.5x16, but I spent from sunset to complete darkness looking through a couple of scopes, one of which was a Monarch, and I was very impressed with it. It's just a plain old 4x40.
Again, congratulations on the elk, and please post on the scope.
