M46 the large Open Cluster lower left, smallish blue stars, you can't miss that.
M47 the large Open Cluster centre right, brighter blue stars, more sparse.
NGC2423 the large less distinct white Open Cluster top right.

231+ 4.2 the bright Planetary Nebula at the top of M46, blue-ish with a
red left edge. Known as the Calabash or Rotten Egg nebula, by some
anyway.
It was taken on the 26.11.09. I didn't focus as well as I
should have. I used the FLT98 and M25C for 15 frames of 120sec. No
flats or darks were used. Guiding was reasonable.
