Mudderchuck, if you would turn your scope down in power until the exit pupil is 5mm or larger it'll suddenly magically become bright. you have a 52mm objective lens so as long as you keep your scope turned under 10x it'll remain as bright as it's possibly going to get. See your eyeball pupil will open to about 5mm under low light so the exit pupil of the scope (the size of the image or field of view is over 5mm it's good to go. The exit pupil is measured at the eye relief of the scope from the back of the scope to the distance your eye is. To determine exit pupil you take objective lens in MMs and divide by the power or x of the scope. It changes with the power.
