So the covered walkway is so you don't have to slog through the snow to get to/from the telescope, yes? The parallel of the 'Looking back at Tucson' shot with Mount Wilson is remarkable. Clean desert air! Folks might be interested to know that the Catalina Schmidt is presently the most productive telescope in the world as far as near-Earth asteroid discoveries (and comets, too). Amongst us long-time telescope-operators Rik Hill is well-known as the the guy who did almost all the observing with the Burrell Schmidt at Kitt Peak, completing several major spectral surveys (the last ones, actually) during the 1980s with that instrument. \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
