Very structured galaxy. Three spires are obvious. The “S” shape made by the two longest ones is well visible. Center regions are very concentrated, with a stellar nucleus, about m15v.
HII regions are numerous and precisely analysable along the three spires. More details in my web site (with, unfortunately, observing notes written in french)
