Description: you've got to be a stargazer (ie someone "strange" to ordinary
people) to be alone in the cold dark night concentrated on complicated
equipment at midnight on Christmas day... not evident to find because some
star groups are interfeering; group of 6 stars of mag12 and 10 of mag13-14
on a 5' diameter area; a mag9 star (appearing on Uranometria 17 and MSA I
suppose) is at 10'NE; a fuzzy mag13 star is at 5'W and another group of 3
faint stars is 5'W of the mag9 star.

I can provide a scanned scheme of IC 166 to anyone who can read the binhex
encoding of Eudora (for Mac); just mail me to try
(ypothier@abi.snv.jussieu.fr), it works sometimes with other
