The problem with mirage moving the target is determining where it actually is at the moment you shoot.

Here’s how to do it.
Start with a cheap length of Picatiny rail blank you can get cheap on ebay

Drill and tap it for ¼ – 20 thread in the center so you can mount it on a camera tripod.
Mount a 24X rifle scope on a QD Pick mount (again cheap on ebay) and mount that on the picatiny rail.

Now mount the tripod to your immediate left as close as possible when shooting, so you can “just about” see the scope with your left eye while looking through the scope with the right.

If you focus the scope on the target and adjust parallax out you can now watch as the target image displaces in the mirage.

If you always aim at where the spotting scope reticle is pointing, you will have a constant point of aim on paper regardless of where the target image appears

I welded up a short purpose built tripod with spiked feet with a manfroto pivot head to get in rear tight.

You can actually do the same thing with an Olympus Micro 4/3 camera and a 300 MM lens instead of using a rifle scope. Use an old computer monitor to see what the camera sees and use rubber bands as cross hairs to replicate a reticle in front of the screen.

Make sure you turn off image stabilization.

Just aim for the X every time

You might need a 110 volt cigarette lighter converter and an automotive jumper pack for power

Make sure you turn off image stabilization.

Just aim for the X every time and you will always be shooting at the same place.

Have fun guys.
