DLO Live! Quick Take. Collimators and Tracking

I have three scopes here to put on a collimator and do a rudimentary tracking test. Normally, this is not the most interesting thing in the world to do, but it needs to be done. This time around, I figured I can hook up the camera output to the computer and show you how this works. Swapping between scopes involves wobbly camera pictures and other unpleasantness, so my apologies in advance.
The three scopes I am looking at are Telson Toxin 3-18x50, Steiner H6Xi 2-12x42 and Burris XTR PS 3.3-18x50.
Naturally, this will also give you some idea of how the reticle presents itself.
