| NGC7538 |
NGC 7538, also known as Sh2-158, is (principally) an emission nebula, in Cepheus. It is surrounded by larger
nebulas, and a few NGC clusters. This photo is the beginnings of an LRGB photo; 3hr of unbinned LUM combined
with 1 hr of binned (2X2) Ha. It was taken with the H9, on the SPX250 in September 2008, under high altitude clouds.
