Description: large and medium in brightness, easy to see, more scattered
than nearby M52, dimensions hard to determine because the cluster seems to
have no definite limits, maybe 10 to 12'; 10 stars of mag.11-12 and 20 of
mag13-14 are scattered upon this 12' area; with a mag.9 star on the
Northern border. M52 stands approx. 20' to the North, smaller than Cz 20.
I can provide a scanned scheme of Czernik 20 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
