At our astronomy meeting tonight, we had a lecture on how to collimate a Newtonian telescope. My friend John, standing at left, was the lecturer. He is a master Amateur Telescope Maker and mirror maker. "Collimation" is the process of aligning the optical elements in a telescope for the best performance - in the case of a Newtonian, the two mirrors which make the telescope work. Here John talks with another member, as a third member, in the foreground checks the alignment. I love this photograph because there is so much going on in it. This is about the most action you are liable to find in one of my photographs!

The hand jestures absolutely make this photograph!
I agree with Ken Schwarz. The man in the foreground reminds me Lauren's Dad.
