LDN 673


 At a distance of about 600 light years from us, LDN 673 is a beautiful dark nebula covering almost a full degree of sky in the constellation of Aquila. The nebula is superimposed upon the thick molecular clouds within the Milky Way. The dust in these molecular clouds scatters the blue light from these stars, giving the surrounding stars a decidedly yellow-red bias.

Barnard 138

 

In this photo we see a curved, dark marking, B 138, finally ending in a sharp, black spot. The curved object looks like a great, black lizard. Its head is the sharply defined black spot, B 139.  The "lizard" even has legs, one of which is a sharp, dark projection, B 137.
