More aggressive processing of the original image shows the extent of the two emission nebulae, IC 405 and IC 410. IC 405 is also known as the Flaming Star Nebula.

This view of central Auriga was obtained with my modified Canon 5D full-frame camera that responds well to deep red wavelengths.  We see a good rendition of the two IC nebulous regions in the center, and there is a tiny nebulous spot east of the main group of clusters centered around M38.  I was not able to find an identification of the object, but found from one of the on-line surveys that it is an actual nebula.  We also plotted a good number of the open clusters in this area of Auriga, including one that I observed as part of my Herschel 400i survey: NGC 1664.  As far as I recall, the cluster NGC 1778 is one I have never observed.  Unannotated image.
