PS. I'm very happy with my Armasight Zeus 3 640 75mm 30hz. It rocks! I'm completely disappointed that it's successor, the Zeus Pro 100mm was so poor. In Armasight's defense, maybe I just got a bad one. Steve B. at Nightvisionguys took it back. He has been great. Really, I am just so, so disappointed that the next gen scope, instead of spectacular, was the opposite. I would even trial another one, if I wasn't on the hook for $10k. Still I have faith that the Armasight Q14 ( yes even with its 19mm objective), can be the lightweight ~ 6oz spotter scope. I've ordered it. I think it's going to be fine. Regardless, you won't see any further notes from me on this conflicted forum. Tschuss!
