I plan to get out this week...as soon as the high clouds roll over and I polar
align the solar scope mount. I'll let you know.

This is a second call for observations in Ursa
Major west of 11 hours Right Ascension. So far only two have been sent -
Charlie Whiting and Rick Rotramel. A number of my observations have been
added but I'd really, really like for more to be turned in by SAC
observers.
Not sure when our new, esteemed, editor wants the
observations, me suspects middle of next week. So we have some time but
let's not tarry around and overlook this opportunity.

This call is for the objects that are west of 11hrs
Right Ascension, the lists of which follows. But you need to know that
observations sent a few weeks ago were lost. This includes, if memory
serves me correctly, Charlie Whiting, Dick
Harshaw and Rick Rotramel. So, could you 3 gentlemen re-send your
observations.
Here's the list for the upcoming
installment.
For a
re-beginning the first constellation will be Ursa Major but we will confine our
observations to the west of 11 hours Right Ascension. Naturally this means we
will be looking
at galaxies, galaxies and more galaxies so get ready. The selections seem to
be in 2 major
areas and we will start with the more southerly one. That means the very first
is
NGC3184 a pretty bright barred spiral near the Leo Minor border. Can you see
the attached star in the
northern part of the spiral arms and the 2 very faint HII regions connected on
the west side? These 2 regions are
labeled NGC3180/81. A little more
to the north is NGC3198 another barred spiral but is elongated rather
than face-on. Can you see any bar
structure for these 2 galaxies.
Also, can you see the double star just off the northern edge pf
3198? If so estimate magnitudes,
position angle and separation. Now,
moving to a more northerly position find NGC2639 towards the southwest
corner of the constellation. It is
bright elongated and has a brighter middle. So what other identifying feature
do you
see? Next is the barred spiral
NGC2787 found a little more than 3° west of M81. What about the several faint
stars
involved and near-by? While at it
what is it about the bar? Now for
Coddington’s Nebula, named after Edwin Coddington and is IC 2574 listed
as faint, large and irregular. Keep
in mind that Coddington also discovered 1 comet and 3 asteroids. Now, moving
closer to the 11h limit is
NGC3310 found up near the bowl of Big Dipper. This is a peculiar barred
spiral. What seems peculiar to your eye? Our final selection, near the west
edge
of the bowl is NGC3488 and isn’t very bright but a little elongated. In his
72” telescope Lord Rosse called
it considerably bright. OK we don’t
have a 72” telescope but out optics are far superior, so would you call it
considerable bright. Finally
amongst the selected galaxies NGC3184, NGC3198, NGC2787 and NGC3310 are
Herschel
400 objects. So if you haven’t
started the Herschel 400, now is a good time to
start.
