| Notes: | IC 5146 is more famously known as the 'Cocoon' nebula. This wide field image (by Adam Block/NOAO/AURA/NSF) well shows its position in the Milky Way at the end of the dark lane B 168. According to "Star Clusters", by Brent Archinal and Steven Hynes, the open cluster Collinder 470 is 'involved' with IC 5146, but is not equal to IC 5146, and is cataloged as a separate object |
