Hi to all (again),
=46or its next special file, Ciel Extreme (french deep sky journal) is
searching for observations (visual descriptions and drawings, photos and
ccd shots) of the galaxy cluster based on  NGC 4169, 4173, 4174 & 4175
(Vmag of 12.2, 13.0, 13.3 & 13.2, dimensions of 1.8'x0.9', 4.7'x0.8',
0.7'x0.3' et 1.9'x0.4' respectively). The group is at 12h12m25s et
+29=B010.5' in a 4' wide area (chart 107 in Uranometria & 7 in Sky Atlas) in
the constellation Coma.
All observations (even negative reports are worth knowing of) are welcome.
Each participant will receive a copy of the file generated (in electronic
or paper format as prefered).
clear skies and good hunting, Yann.
