What tricks you use to minimize the fata morgana?

I like the high power scopes, I have two of these and one LPVO.
Falcon X50 10x50-60 I have a sunshade for this one, but the Nikko Nighteater 8x32-60 came to me from second hand and no sunshade.
Shooting my airguns in mid day, the mirage is messing a little bit the higher power Falcon at 100 meters rings, but the Nikko Stirling without a sunshade already showing the mirage at 50 meters.
I was looking online and cannot get anywhere the thread size (M63x08).
I can still wrap my mouse pad around the scope bell, but I would like to get it more fancy.
What you using? DIY?

Just say mirage. That's a weird term for it.

1. Dial your magnification. This changes the light transmission through the lenses so you'll either see more or less of it. If your goal is to minimize it, Id dial in completely then back off until you don't see it as much. I stay clear of sfp stuff for this reason.

2a. Dial parallax closer to you to help detect the mirage.

2b. I'll dial the parallax on a spotting scope midway to help catch stuff like boils, direction of movement or mid flight projectiles better. Coupled with a reticle you can follow your elevation fairly accurately at longer distances past say 300 meters.

3. If you're getting barrel mirage (unlikely on an airgun), perhaps consider a mirage band over the barrel to help deflect the heat from rising in direct field of view. This one is probably the most annoying to deal with IMO.

There's probably a few other tricks I've forgotten.

Started 3d it printing today, right now the second prototype part is in the machine.
Printing just a short tube version for now to find the thread-pitch matching to the scope (some weird thread size, M63 x 0.8 or somewhere in that ballpark).
If that works out I will repeat in a full length tube maybe 150-200 mm.
