Collimating a SCT with a Tri-Bahtinov Mask

I was recently asked by a subscriber if I could create a video explaining how to use a tri-bahtinov mask to collimate a Schmidt-Cassegrain telescope. So I hope this is helpful to all SCT users that are thinking of purchasing one of these focus/collimation aids.
