Description:
Due to kid duties, I got home unusually early yesterday (3/6). This allowed
me to work on collimating my scope more thoroughly than I have in a while,
and it also allowed me to let the scope start cooling down earlier than I
usually can. The result was my best session of the year despite a very light
haze / cloud cover. I'm estimating that the limiting magnitude was in the
5.0 - 5.2 range.
Instrument - 20" Starmaster dob
eyepieces used - 38mm Rini (63x), 16mm Nagler (150x), 9mm Nagler (263x)
[Deleted descriptions of Jupiter, Saturn, Comet Ikeya-Zhang, as this is a deep sky group :-) ]
After putting my kids to bed at 9:00, I decided to look for galaxies in and
around the Beehive (M44), as I've seen someone post their effort at this
recently. A good dark site would help this immensely, but here's what I came
up with. All of these objects are within 2 degrees or so of M44, and all are mag 15 or under (according to Sky Map).
Wanderings around M44 (Beehive):
STF 1254 - A nice, wide triple/quadruple star in the heart of M44. Nice
color contrast between the three brightest (mag 6.42, 7,59, 9.16). Should
look very nice even in a small scope, perhaps in larger binoculars as well.
PGC 24400 - mag 14.6 galaxy was barely detectable with averted vision, but I
could pick it up consistently at both 150x (16mm) and 267x (9mm).
NGC 2624 - mag 14.7 galaxy barely detectable only with 9mm (267x); not
consistently detected, but I'm fairly certain that I saw it several times.
STF 1249 - not particularly exciting, matched double (mag 10.76, 10.97; sep
25")
IC 2392 - Fairly large, dim (mag 14.6) galaxy. Needed relatively high power
(267x) to get bright star (delta Cancer) out  of the field of view.
PGC 24485 - couldn't find this mag 15.0 galaxy even though I'm certain that
I was in the right spot
PGC 24656 - couldn't find this mag 14.8 galaxy even though I'm certain that
I was in the right spot
NGC 2667 - mag 14.9 galaxy. I think I saw it (I think I can, I think I
can...)
NGC 2672 - finally, a galaxy that doesn't require averted vision! mag 12.6,
fairly large and round (2.6' x 2.5'). I could not distinguish the mag 14
galaxy NGC 2673 that is basically visually right on top of it
