NGC1491 - Fossil Footprint (Maybe?)

NGC 1491 or Fossil Footprint Nebula (a.k.a. SH2-206 and LBN 704) is listed as a bright emission nebula and HII region on Stellarium. It is located about 10,700 light-years away in a gaseous region in the constellation Perseus on the edge of the Perseus Arm of the Milky Way. In recent times, this has become a popular object to image but it is not easy due to its variable brightness. The central portion is plenty bright, however, the outer regions get quite dim.

The massive star within the gaseous region, 11th magnitude star BD +50 ° 886, produces radiation which inturn ionizes the hydrogen gas that makes up the nebula. The bright pillar to the left of the star points to it and if you look closely you may notice a bubble or cavity surrounding the star.

There is some amount of oxygen and sulfur as well but I used the ZWO ASI294MC Pro (one shot color camera) with the IDAS NBZ dual band filter which only picks up hydrogen and oxygen. I am not sure I see the 'Fossil Footprint' in this nebula but I am sure someone with a better imagination than I can.
