SH2-112, SH2-115 & PN Abell 71 in Cygnus

Image Description and Details : Here are the Sh2-112 (left) and Sh2-115 (right) nebulae in emission, together with the beautiful Abell 71 planetary nebula (PLN 85+4.1), in Cygnus.


The Ha clouds that dot this area are just a small part of the giant hydrogen cloud that stretches across most of the constellation, some 6,000 light-years away.

The planetary nebula is located closer to us, some 2500 light-years away...

Note that for this image, I've kept the palette from the mix without playing the selective corrections, in an attempt to best render the two main nebulae.
