I suspect you have not read this thread completely or the other thread that I started back in 2020:
Since I can't shoot rifles at long range during the Wuhan virus pandemic, I can at least think about it. So, while reflecting on the atmospheric vagaries than engender issue looking at a target on 1000 yards, I dedicate a few neurons to try to explain why I believe that ED glass helps tame the...

I would also point you to a short article of mine that was posted recently at the Marchscopes.com site:

Go read those and then come back here. I'll wait...
Ok, now that you have read up more about mirage ED glass and how to use the Majesta, let me add some more information.
As was stated several times in the pieces that you just read, ED glass and especially Super ED glass control CA and in the case of Super ED, the CA control is indistinguishable from that of pure fluorite crystal (CaF2) glass. It was discovered that ED and even more so Super ED glass reduced the IQ degradation due to mirage. I hypothesized why that would be so in that other long thread, and DEON published an article about that a few years back.
But what does that really mean to the competitor shooting a match in heavy mirage? As I said multiple times in the past, the IQ of the Majesta will degrade, and the image will not win any photographic awards as it can be downright yucky. (Sorry for the technical term here.)
On the other hand, and as opposed to other riflescopes, the target remains shootable. By that I mean that at 80X in mirage conditions, the image of F-Class target at 1000 yards can still be counted on to place the reticle surgically on the target and take the shot without worrying that the target is not where we think it is. The aiming black is still round, the rings are still distinct and identifiable. As I said, the target is shootable, whereas in other riflescopes the aiming black is acting like an amoeba on crack and the rings are just one big blurry mess, if they can even be seen at all.
I started to write about how I arrived at the final design for the MTR-WFD reticle in the Majesta based on observations in mirage conditions, but we'll leave that for another day. For now, suffice it to say, that it's important to understand WHAT you are seeing in the riflescope and find out how to make it work for you.
There is no other riflescope on the planet that presents a wide-angle (25° AOV) picture of the target all the way to 80X. When your brain (which is the most important component in interpreting what the Majesta is presenting) is accustomed to seeing the image of the target at 80X in various conditions, you will be able to use the advantages provided by the Majesta. In the MTR-WFD reticle, I built in some cues that will further help the F-class shooter hold the waterline in bad mirage. Will the IQ of the Majesta (or any other optical riflescope) ever go beyond the yuckiness (there's that technical term again) presented to your eye (and then brain)? Nope, but the target will remain very shootable and that's the important part.
