Abell 2199 expand

This target really pushed by telescope to its limits. With galaxies having magnitude over 15.0, it was really hard to get details on them. Abell 2199 is a galaxy cluster located at the southern part of Hercules. The central and "biggest" galaxy is NGC 6166 which is an elliptical galaxy and lies about 490 million light years away from earth. More than 80 galaxies can be seen in the photo if someone notices carefully. On analyzed overlay, every blue circle contains a galaxy.
