Thanks for the comments much appreciated
CheleA, sounds like a great trip. My plans are to drive down again in 2016. I will try to hit all the ruins I can.
Nighthound, I looked at your astro gallery. Very nice! I am an old astro photographer. Haven't done it in years.
I used cooked Tech pan 2415, and Konica color film back then. 12.5" reflector and a Scheafer mount. I still have all the gear in the garage.
