Are you using a tripod to get such seemingly reproducible framing?

If it’s handheld, you are a wizard!

Tripod of course, a carbon one, not too heavy as exposure times for UV are 8-10x the visible ones. Otherwise no chance to get somewhat matching images (despite that, there is also wind, you know...)

Makes sense! I was thinking you had such a perfect sense of 3D space like a real predator!
