This 8th magnitude comet is currently near its peak brightness, and will start to fade in the coming weeks. A very strong cyan coloration dominates this object, the Swan emission bands are strong here. Only a hint of a tail is seen as a greenish brightening just below the comet, best seen in the smaller images such as above due to being a very low surface brightness. The comet is currently very easy to find, being within the "Keystone" asterism of the constellation of Hercules.

Processing: 30 RGB images combined in Maxim DL, with Photoshop CS2 used for final brightness and contrasts.
