Description: alpha looks yellowish and the "cluster" is about 2.7°x2.4°
along a NW-SE axis between Alpha and Psi PER; contains about 15 bright
stars (about mag.2 to 6) and about 10 fainter (mag.6 to 8); a remarkable
and evident group indeed. Nice with naked eye too.

I can provide a scanned drawing of Melotte 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
configurations...
