I can still see to shoot well past sunset with any of those scopes. Have checked that many times on my way back to the truck after a hunt. From what I've seen, many if not most southerners hunt out of blinds or stands overlooking fairly open areas. Fiields, food plots, power lines, pastures etc.. I can assure you it's darker at sunset in a hemlock swamp than it is a half hour after sunset in the open.
