JPK-
Are you saying that I'll get better results punching the center of the scope cap for night use?
krm, as I wrote, with an independent IR source, like a T20, you will get a cleaner view with less graininess punching out the 22mm center piece. Whether this is true with the built in IR source, I am not sure yet. I hope to test but stuff keeps getting in the way.
Keep in. Ind that you need to reinstall the centerpiece to shoot during daylight.
