Messier 30 is a globular cluster located in the constellation of Capricornus. Due to its retrograde motion in respect to the general flow of the Milky Way galaxy, it is thought to be c captured cluster from another satellite galaxy. Having under gone core collapse, its central section is dense with stars. A class V globular cluster.
The bright star is Zeta Capricorni.

If globular cluster NGC 5897 (2022) ranks low on the Shapely-Sawyer concentration scale, Messier 75 comes out at the top of it's class with a rank of 1 (I). If it wasn't for being on the other side of the galactic center, it would be much more spectacular to image. The cluster has a radius of 67 light years, and contains some 400,000 stars. Would definitely be a sky full of bright stars if one was located inside the cluster.

NGC 5897 is a globular cluster that is a satellite globular of the Milky Way Galaxy. Forming at or before the formation of our galaxy, they typically range in age of 10-12 billion years old. Age is estimated based on the amount of metal located in the stars, which is considered to be anything other than hydrogen and helium. It's measure of metallicity is measured at -1.9 (Fe/H). NGC 5897 has a low density of stars, and using the Sawyer Concentration class which ranges from 1 to 12 (most to least), it is ranked as a low 11.

Messier 2 is a globular cluster located in Aquarius. Containing around 150,000 stars. it is also one of the older and largest of the Milky Way globular clusters. Esimated age is 13 billion years and spans 175 light years in diameter.
Was using it as a test object for my new to me camera.

A relative small globular cluster possibly due to close encounters with the Milky Way Galaxy. It was possibly a former member of the Sagittarius Dwarf Elliptical Galaxy having been stripped away by the Milky Way Galaxy.
Also of note is the galaxy UGC 7170 in the lower right. It is a super thin galaxy that lacks a central bulge, and the tips of the disks are slightly warped. Super thin galaxies are underdeveloped systems with minimal amounts of interstellar material in them.
