Steve, Thanks for bringing back some good memories. I always thoroughly enjoyed Sentinel while I was in Arizona. If you want to feel better about Arizona observing weather, I was observing Saturn from my back yard tonight and my Telrad ICED over. (Saturn was outstanding in the TV102 at up to 293X, so it was worth all the work with the 12V hair dryer).
