Low light? I'm probably not up yet, or already in bed.... These 18-20 hour daylight days are tough on a guy!
Just kidding - I carry flashlights to help find camp.
The first moose I ever shot was with Marlin .30-30. It was so dark that I had to sight against the sky first, then drop it down to the moose some 50-70 yards away. Three times I did this, until I was sure of my aim point/bullet placement.
It had open sights.... I doubt a scope would have worked.
