Subject: [sac-forum] Canis Major observations
I need for everyone to submit their observations for objects in CMa for the
upcoming March newsletter. So far I only have observations from Rick Rotramel
and Richard Harshaw, but I need much more observations. As a reminder here's
the list of entries that appeared in the last SAC newsletter. Please get your
observations to me by this Wednesday at the latest and I'll be certain to get
them in.
For the next month's installation turn to the Greater Dog of Canis Major where
we can get away without looking at any galaxies - for a change. Beware you may
need a finder chart for a couple of these objects, so be careful. We start in
the northern reaches and work our way to the south. So for the beginning
locate the open cluster NGC2204 in the extreme northeast part of the
constellation. It should be easy to find owing to being a Herschel 400 entry,
rather large and rich with over 50 stars. Second, in the same area is IC2165 a
planetary nebula that is nearly stellar. I suggest you have some kind of
finder chart for this one. Moving eastward some find Berkeley 25, obviously an
open cluster. In case you don't have easy access for locating this cluster it
can be found at R.A. 06 41.2 Dec -16 29. Moving south of Sirius is an easy
find in M 41. It should be visible in your finder, but what is smallest finder
in which it can be seen? Send your results in. Next is an interesting open
cluster I haven't heard about nor seen, although it is in the SAC database. It
is Auner 1, located at R.A. 07 04.3 Dec -19 45. It is rather small and has
about 30 stars.

In the above image, from the Digitized Sky Survey, the brightest star just to
the north is 9th mag TYC 5972 2901. You knew that didn't you? The next open
cluster is Haffner 23, located at R.A. 07 09.4 Dec -16 57, is fairly large but
rather faint. Meandering to the southern part of the constellation you will
find NGC2384 that is fairly bright and a little compressed. Before our final
object take a look at the asterism called Mini Orion. It is located at R.A. 07
17.0 Dec -24 21. It should be a naked eye object at 5th mag, 15' and has 6
stars. The final open cluster is NGC2243 and should be pretty bright to your
eye and easy to find.
