... Cocoon Nebula . IC 5146 + Sharpless 125 is a cluster (80 members) with an emission and reflection nebula that surrounds the star BD +46°3474 and is 3900 light years away in the constellation of Cygnus. The B-Type star BD +46°3474 that illuminates the region, is a foreground object to the large molecular cloud complex. The dark regions trailing away from the Cocoon are the Lynd's Dark Nebula 1035 and 1045 (LDN 1962). ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...
