Comment |
North is to the right.
IC 5067 is the
elephant trunk region of the Pelican Nebula, which also includes
IC 5070. This HII region is located in the Cygnus constellation, at a
distance of about 2,000 light-years.
This RGB image is an approximation of human vision. The overall red
color is due to the dominance of ionized hydrogen gas.
