Description: quite large cluster of medium brightness, lightly condensed
and not well detached; about 30 stars of which 2 are about mag10, 15 of
mag11-12 and 10 of mag13-14; estimated dimensions about 14'x10' along a
NNE-SSW axis; a more crowded area 9'x4' elongated on the same axis is
noticeable along the NW edge taking half the cluster's dimensions; a mag10
star is offset from the center to the E and another of mag10.5 is just
outside the cluster to the NW.[On Guide, NGC 886 appears as a ? symbol
within Stock 6 boundaries, so it seemed to me that the two clusters were
the same; they appear under the same identity in Luginbuhl & Skiff.]

I can provide a scanned drawing of Stock 6 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...
