This globular cluster is about 33,000 light-years away from Earth and is roughly 84 light-years across, containing 230,000 solar masses. At an estimated 13.7 billion years of age, it is almost as old as the universe itself.
It has been conjectured that it is a remnant of a dwarf galaxy merger with our Milky Way galaxy.
This RGB image is the result of 2h of data capture from Horsham over three evenings in July 2024. A ZWO ASI2600MM Pro camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien reflector.
