Check the Mueller Eraticator. Has a red illuminated dot with ~10 different brightness settings. Power is 8.5 - 25 x 50mm objective. Seems like too much power but it really works well. Killed a gray last year at about 50 yards with no problem finding the target. Usually keep it on about 15-18 power and turn up and down as needed. I have one on my 22-250 and .17 hornet. Best thing is it won't break the bank at $250. As Buckwheat mentioned - watch your cross hairs aren't too heavy. This Mueller has a fine line for a cross hair. At night I have one single red dot in the scope and with two red eyes from a fox / coyote, just line up the 3 dots and squeeze the trigger!!! Then it's "lights out"!!!!
