Description

Here we see Sh2-73, an integrated flux nebula located in Hercules.  It was initially misclassified in the Sharpless catalog as an emission nebula. However, Sh2-73 is not illuminated by a proximate star, but rather by the integrated starlight of the Milky Way galaxy. 

In addition to Sh2-73, the image reveals numerous background galaxies which include:

NGC 6060

NGC 6032 and NGC 6035

NGC 6052

As well as a whole bunch that don't seem to have catalog names.

These galaxies are quite bright relative to the IFN and required careful application of masks and HDR techniques to reveal their detailed structures.
