Corwin's Notes
=====
NGC 1146 is a group of four stars near d'A's position. He mentions a triple
star near to the south -- that is what Brian Skiff and Tom DeMary have taken
as the object itself, Brian noting that it is the southeastern of two groups
of stars.
For some time, I had thought that the NGC number applied to both groups.
Seeing d'A's full description has finally made it clear that I was wrong.
Here is what he has to say (my translation): "Cluster, very small and not
rich. At 226X some nebulosity is seen. A triple star is close south."
Aside from there being no nebulosity, this is a very good description of the
field. Perhaps some of the fainter stars nearby lent the appearance of
nebulosity on a less than perfect night.
Finally, Wolfgang Steinicke got the right asterism a decade ago during his
early work on the NGC.
Steve's Notes
=====
NGC 1146
18" (11/23/05): this asterism consists of a 30" pair of mag 12/13 stars with a couple of fainter companions making a quadruple. About 1' NW is a faint, hazy clump of three mag 14-15 stars. Viewed at 225x and 300x. CGCG 554-017 lies 6.2' NE. Listed as nonexistent in the RNGC.
