Sh2-206 is also known as NGC 1491 or the Fossil Footprint Nebula. It is an emission nebula located approximately 10,700 light-years away in the constellation Perseus. The nebula gets its deep red coloration from the ionized hydrogen gas. The “Fossil Footprint” nickname comes from its distinctive shape in images.
It is a typical target for astrophotography during the late autumn and winter months in the Northern Hemisphere. Astrobin link for acquisition details and annotation.
