M38 and LBN 794

M38 is one of the three major open clusters in Auriga and one of the most observed and imaged objects in late autumn. Much less known is the faint nebula nearby, named LBN 794 and extending toward South-West toward the IC405-410 complex. To extract the most of this faint object I've collected 6.5 hours of exposure.
