An image of the lonely globular cluster M30, well, there are a few faint galaxies around, but as an structure, it is alone. Also it is quite interesting the different colour of the stars in the cluster, a much larger image would have been ideal. I found some interesting reading that motivate to get the image, even within the obvious limitations, but it is great fun anyway.
According to the information on the web, it is one of the few globular clusters that has a retrograde orbit, which maybe tells something about its capture. Also it has a very dense core, actually one the more dense regions, and it is considered to have a collapsed centre.
It was studied by Chandra X ray sources due to this condition of core collapse.
If anyone has interest in reading a bit about that, it is in "CHANDRA X-RAY SOURCES IN THE COLLAPSED-CORE GLOBULAR CLUSTER M30 (NGC 7099), The Astrophysical Journal, 657:286Y301, 2007 March 1".
In that publication it is stated that "
M30 (NGC 7099) is one of 21 Galactic globular clusters that show strong evidence of having undergone core collapse...", and gives an idea (for non experts) of the magnitude and impact of the phenomena.
Two nicer images with larger equipment are:
