Description

Close to Pacman is an ignored little group of blue reflection nebulas, IRAS targets and even submillimetric radio fonts.Main reflection nebula of the group is DG6. I invested almost 24 hours of integer subframes just to present in a decent way this image. I attached a prehistoric paint of a horse from Altamira´s Cave (Spain) as it´s very similar to the nebula. Both images are messengers from the past.. one coming by men´s hand (18000 years B.C) and the other by Universe light thousands of years ago..
An annotated image can be seen here also:

Thanks for looking.
Clear skies.
