Randy,
Focus at infinity. Try using the Moon at 1st or 3rd quarter. Once focused then mark the position where the ocular meets the tube or tape in place to prevent accidental shifting.

Greg, thank you for your observation. In principle I agree. The focus should be at infinity because it is the objects reflection I focus on. But with the scope taken off, I looked at low objects standing way back, and I had to adjust my focus for a higher object that I stand closer to get. Shouldn't I be able to leave focus alone if all are at infinity? It may turn out to be the tilt of my head changing the progressive glasses focus. What do you think?
