You should be able to adjust the clearness of your target with the back eye piece. There usually is a small ring you have to loosen, then make your adjustment by turning the eye piece one way or the other to get a clear picture, then tighten the narrow ring again. I just had cataract surgery and had lens implants for close and distance. I had to readjust my scope.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
