NGC 7822

This image did not quite turn out how I was hoping. The framing is 90 degrees off where I wanted nit but I was imaging other targets as well and did not want to through off the orientation of everything else. Additionally, the OIII did not "pop" as much as I has hoped. I have seen other images of this region where the OIII signal is quite strong. I am thinking that I might need to bump up my exposure time, even with the high gain settings. I will definitely revisit this target in the near future, hopefully I will have an S2 filter by then.

Info:
NGC 7822 is a star forming region located 3000 light years away in the constellation Cepheus. The molecular cloud complex which gives rise to the visible nebula is known as the radio source W1 (Westerhout 1), one of the largest molecular cloud complexes in the Milky Way.
