When using any scope in low light conditions you must lower the power. You can't use 20x in the dark and expect to see anything no matter what brand of scope your using. The lower the power the clearer the target in low light conditions.
No disrespect meant, just offering a tip to help achieve maximum performance from the optic.
I own 5 Nikon scopes, 4 Monarch's, Nikon Binoculars and Nikon Range Finder. After purchasing my 1st Nikon product I would not consider buying any other optic.
Pros: Superior Optics, especially in low light conditions
Cons: None
