Ok here are a few using the same camera but through the Gen 3 740.
As you can see trying to get the camera lined up with the scope while getting the rubber eyepiece on the scope to compress just right is a bitch
740 with IR illumination from a Surefire 6P
740 with no IR cross hair on low setting
Again notice the green plate second from left.
740 with no IR Crosshair on Hi setting
In this one the black plates are not as visible as the whites
I tried to do this with the Gen 3 VisionMaster 2-10x56 Day/Night scope but dealing with the rubber eyepiece on it was impossible so I gave up.
This is certainly not a scientific undertaking and the quality of the photos leave alot to be desired but again, in "my" opinion given the yardage and given
the background I think white stands out better.
In a previous post I spoke about being able to find center mass on white better than black and Muderman spoke of the sound of hitting steel which I perfectly understand
but my point was I want to hit the center of my target, like hitting a bullseye. The clang on steel just means you hit it but it does not mean you neccessarily put the best hit on it.
Hitting an IPSC steel target on a lower edge will get you a clang but not a quote unquote kill.
