Fantastic report Gary,with images to match.
Makes me want to go back again.
Very jealous of your observing with a 22" at the 9000' mark
I used the 11" at what is now the visitors center 30 years ago.
Helped the night guide out so he let me use the scope for a while
after all the visitors had left.
Definitely an observing trip of a life time for you
Thanks for sharing.
Cheers
