Comments: This was my first attempt at a mosaic image. It was taken, processed and published in 2008.

This nebula, which is about 3,300 light years distant, lies among some of the richest star fields in the northern Milky Way (as one can see, there are a lot of stars). First noted by British double-star observer Thomas E. Espin, this complex nebula seems to sit at the end of a long, star poor path. This "path" is actually dense gas and dust which obscures the light of the stars more distant to it. In this image, the background has been carefully adjusted so to show the obscuring dust in the region. As you can see, the dark dust lanes vary from moderately opaque to deeply obscuring. There is a lot of dust in the region. Van den Bergh 147 is the small reflection nebula just to the lower right of the Cocoon.
