A deep look at this interesting little emission/reflection nebula which is near the Bubble Nebula. Also goes by NGC 7538. Narrowband SHO palate with RGB stars. Taken with from backyard...so not quite the detail I hoped for, but still I'm pleased. OK, you CDK14+ guys...go for it[b]![/b] -john
PS don't know what I'm doing wrong, but I couldn't get any stars to plate solve even though all checked.
Best description I could find: NGC7538 (SH2-158) is a region where numerous stars are in the early stages of being formed. The nebula is also home to one of the largest discovered high-mass protostars with a rotating disk that has a diameter of about ten times the diameter of our solar systems (about 800 AU). The protostellar phase is the earliest one in the process of stellar evolution and while we still don't know very much about high-mass protostars, it is assumed that they are surrounded by an accretion disk that drives molecular outflow, like the low-mass protostars. The accretion disk in NGC7538 is very young and extremely massive, and is in the process of forming one or more high-mass protostars. NGC7538 is about 7000 light years away in the constellation Cepheu. from AstroBatch
