IC 5332 (ESO 408-9, PGC 71775 and others) is a faint face on spiral galaxy located approximately 33 million light-years away in Sculptor.

 

There’s a large cluster of galaxies at the bottom left. These are part of Abell 4010.

 

At -36 Dec, IC 5332 was only 21 degrees high on the meridian. Poor skies also contributed to the rough data.

Hi all:

NGC is a spiral galaxy in Ursa Major that's about 195 million LY distant:

http://www.greggsastronomy.com/IMAGES/ngc2998-LRGB.jpg

At the upper left are NGC 3009 and NGC 3010a,b,c.  Several other NGC objects are in the same field near 2998.  NGC 3002 is also cataloged as MGC+07-20-052 and appears as a distorted double galaxy (MGC+07-20-052 NED01, MGC+07-20-052 NED02).  In the map below 3002 is plotted twice; one is a star.  NGC 3004 is also just a star.

It is the home of many star clusters including Trumpler 14 and 16. Trumpler 16 contains WR 25, the most luminous star in the Milky Way, which can be seen near the center of the image. It is one of the largest nebulae in the night sky measuring over four times the size of the Orion Nebula. This images captured with 5nm narrowband filters (Ha, SII, and OIII) and processed with the Hubble palette.
