I mean, I don't run in circles screaming if the moon comes into view. I often get the moon when panning around stargazing. I just don't stare at it. I can't remember what light source I hit one time, not for all that long, that left artifacts in my view. Turning the NODs off and back on didn't clear it, but leaving them off for a while did.
I have really good autogating on mine, but from reading, the more the autogating has to kick in and the more bright stuff you look at, the faster the life expectancy goes down. I don't know if that's a large or small number. I have done a couple of stupid things, like walk back into the house with the NODs still on, and not realize it for a minute or two. No apparent harm done. This video actually just left me feeling more comfortable about not freaking from doing dumbass stuff.
