[SNIP], i dont take the scope out when it's below 45 degrees! It
makes for bad seeing anyways. [SNIP]

Chas,

Not always. I took Sue's 10" f/6 out one very cold night to measure where
all the eyepieces focused in preparation for mounting a new focuser. It
turned out the seeing was quite good, and I had some unexpectedly fine views
of Jupiter. In general, though, you are right, and it is a good excuse for
staying in on cold nights g.

Clear skies, Alan
