An exciting emission and reflection nebula in Cepheus, namely NGC 7538. It
is the host to ongoing star formation and includes the largest known
protostar. This is, apparently, embedded in a collapsing core of 85-115 solar
masses on the way to becoming a high mass B star.
Taken by Rhys Owen from Hatfield on the 8th of September, using a modified Canon 600D on a Takahashi 106FSQ. Guiding was done with a Celestron Nexstar8 controlled by PHD. The exposure was 3x500sec., captured in Nebulosity, calibrated in Astroart with darks, no flats, and finally processed in Photoshop.
