Messier 23 is a large, bright, open cluster located in the constellation of Sagittarius 4.5 degrees northwest of Mu Sagittarii. It can be seen here at the bottom center of the frame. A complex of dark nebulae, the most distinctive of which is Barnard 84a, lies just to the north of M23. B84a is at the top of the frame with a 9.5 magnitude star in the middle of it. Just above M23 are LDN 288 and LDN 285. | |
