[sac-forum] Call for Cancer Observations

 
I know we haven't been having any luck with observing weather, but the news
letter must still go out.  So, if you have some new observations, or even
some old ones, of the following objects in Cancer; then please send them in
in the next couple of days.  The following is cut straight from last month's
issue of the NL.


Observations due for May are for Cancer and are the six brightest in the SAC
database, along with one challenge object.  It culminates at 9pm in late
March.  First we’ll cover three objects in the mid-section, and then
we’ll finish with those towards the south.  So, beginning our tour
start with the beautiful naked eye open cluster M44.   About 2.25° east
and a little south of M44 is NGC2672 an 11.7 mag elliptical galaxy.  Let us
know if you see its 14th mag companion, NGC2673 just to east and involved in
its halo.  Next go 5° east of delta Canceri, Asellus Australis, for
NGC2749 another elliptical galaxy at mag 11.8.  This galaxy has four other
galaxies in the field ranging in magnitudes from 13.9 to 15.5.  How many of
these do you see?  To start the southerly tour find NGC2513 an 11.6 mag
elliptical galaxy about 3.5° west of beta Canceri.  It is a big slew to
M67, but it should be an easy find.  Now the challenge; about 3° south
and a little to the west is PK219+31.1, also know as Abell 31 or Sh2-290;
this 12.2 mag planetary nebula is 970” in diameter, which gives it a
very low surface brightness so use low power here and a UHC.  It is located
at RA 8h 54.2m Dec +8° 55’.  Finally, there is NGC2775 an early
spiral of mag 10.1, which has two other galaxies in the field, one of
13.9-mag and14.5 mag.  Do you see the other two? 

This will be it for Cancer for a while, unless we decide to go for objects
fainter than 12th magnitude.



Hopefully, some interesting observations of the  above will be sent in.



Thanks and clear skies,
aj
