Thanks for the note on the 10x25s, Tal. They sound like a wonderful,
inexpensive way to "always have optics on hand". The fact that Walter
Scott Houston found "simple" small bincoulars handy for his own deep-
sky observing, should be a clear indication to all "serious amateurs",
that they really are useful to have in your observing kit.

Thanks for catching that, Tal! It's always been easy for me to forget, and
mislabel the "head of the cross" as the "head of the swan"! Maybe that is
because Cygnus's neck has always seemed so improbably long to me, that it's
hard to keep the true mythical image in the mind's eye when looking at it.
Maybe I've just never spent enough time around long-necked swans? :)
Clear skies,
