Fact is, hubbles haven't done anything any better in low light than any scope with a smaller objective, in 20 years. Hell, if I had $ to burn, I might splurge wantonly, but I'd rather shoot up a grand, if I gotta choose. Either way, I wouldn't deal with much over 40mm
Perhaps your eyes are so good you see nearly the same in dark as day. My experience is that the 52mm objective has certainly helped me in low light to verify antlers are either branched (legal) or a spike (illegal). One of my friends can see as well without binoculars as most folks can with 7X binoculars. His low light vision is outrageous, also.
