At 80X, first you have to find the eyebox.
Yes, it's very tight at that magnification. I have people coming over to my mat, asking to look through the Majesta. The problem is that I am always at 80X now, so when they first look through it, it takes a while to get situated. However, if I crank it down to something mundane, like 55X or 42X, there's all kinds of eyeboxing going on. The wide-angle eyepiece presents a lot of view.
I usually crank down to 40X or so when I get setup in the morning and line everything up. Then, when I'm good to go, I crank up to 80X and leave it there for the day. Since we use electrornic targets, we are able to set up 3 to a target at Bayou Rifles and we just leave the set up on the ground with EICs inserted while the other relays shoot.
Back to 80X. It's tight, but then again, you need to have perfect form to score well in F-class and once you see the target properly, you know you're set up properly on the rifle. I certainly would not be using 80X in a PR-style match where you have straddle between an overturned rusted car body and a 2-legged barstool using a mirror to aim.
The Majesta @ 80X is for high precision shots in proper position. Beware, once bitten by the 80X bug, anything less seems so far away.
