[sac-forum] Re: Call for Hercules

Jack;

 

I found IC 4593 to be pretty easy in 11 inches of aperture from 

Cherry Road on a good night.  I think AJ has an observation of

this small, but high surface brightness, planetary in the 8 inch.

 

Hope that helps;

Steve Coe

 

Cherry Rd. Nexstar 11 S=6, T=7  22mm--seen as a non-stellar disk.  

8.8mm--pretty bright, small, very, very little elongated 1.1X1, 

stellar nucleus seen 100% of the time.  The disk is light green.

I tried for IC 4593, the White-Eyed Pea, and it is a real challenge object,
and with a 20" too. You have your work cut out for you trying to bag this
one. You might want to skip it and come back after getting the others. I
spent some time at GCSP with high power and UHC to no avail and gave up, but
it sure made Abell 2151 seem easy. I'll try again this weekend.

With the Independence Day holiday coming up I thought a post for the July
constellation worthwhile.  Perhaps some of us will get lucky enough to get
out under dark skies without any smoke in the sky.  As has been the case,
here are the objects for Hercules cut straight from the newsletter article.

Our July constellation is Hercules.  I've chosen the following order that is
not by NGC or RA, but by a somewhat convenient sequence to minimize star
hoping.  So, its on to the objects.  First is the white-eyed pea, better
known as the planetary nebula IC4593 located about 3.8° southwest of omega
Herculis. As with all planetary nebulae look for color, blinking effects and
try any and all filters at your disposal. Second is Abell 2151, the Hercules
Galaxy Cluster, and is found about 50? east of 5 Herculis or almost centered
on NGC6047.  The SAC database notes there are 20 galaxies 14th to 15th mag.
How many do you see in your telescope?  Now slew northeast to NGC6210
(that?s NGC6210 and not the erroneous NGC listed last month) another
planetary nebula located about 2° southwest of 51 Herculis.  Continuing our
northward jaunt take a look at, visible in an 8X50 finder, M13.  At one
time, a long time ago, I had difficulty determining which side of the
Keystone to search.  A technique I?ve found helpful is to go to the
constellation Lyra and find the stars gamma and beta Lyrae, the pointer
stars for Alberio ? hang with me now I'm getting there.  Instead of going
there, go the other way, these pointer stars bring you just north of the
Keystone.  M13 is on the other side of the Keystone from Lyra!  While on
globular clusters, continue north to 4.8° east of northeast from tau
Herculis and find NGC6229.  Finally, slew southwest, to within 2.8°
southeast of chi Herculis and find another planetary nebula, NGC6058.
Remember with all planetary nebulae look for color, blinking effects and try
filters.  If you don't have any, try to borrow one for a friendly observer!

Go out and get a look at these beautiful deep sky objects, consider what you
are seeing, take some insightful notes and pass them on to us! 


Clear, and smokeless, skies to all
aj
