Just want to mention, the reason I posted Jim Scotti's picture of Kitt Peak is because I know about the Calypso because of his pictures. I read about the McMath-Pierce then, too. The Calypso observatory is apparently very nice with living quarters. (drool) It was also for sale, but it doesn't seem like it was sold. ??

It's too early to think of an astronomy question that will be hard, so I'll take the bookish route:

You must not expect to see at sight...Seeing is in some respects an art which must be learned.
