Mark,

It was a great pleasure meeting you as well. I've also enjoyed your
posts here and your articles and I was delighted to have time to chat in
person. You've always been a gentleman and a scholar online and the
reality did not disappoint. :-)

P.S. When (if) that documentary airs you'll catch Mark in it as well.
One shot I'm sure will be used shows Mark high on the 60" Newtonian
platform watching as the shutter opens just above him, revealing a
darkening sky. I'm looking forward to seeing that very cool shot!
