NGC 6229 (3-4-2018)-1j.jpg

 

NGC6229 is the 3rd globular cluster in Hercules along with the much larger and brighter M13 and M92. I found this little gem while star-hopping around Hercules northward towards Draco. Small and faint, NGC6229 is easy to locate once you’ve spotted the two 8th magnitude stars just to the right of the cluster. The late spring and early summer sky hosts several beautiful globular clusters in a broad swath from Hercules in the north to Scorpio and Sagittarius in the south. It is neat to hop from one to another to appreciate how different they can be from one another. M13, M92, and NGC 6229 also make fine targets for the last image sets taken on three consecutive all-nighters. :)
