The small scale
details in this image are captivating. A sunshine yellow core
is surrounded by a halo of arms populated by blue supergiant
stars, hundreds of which are easily resolved in this image. The
galaxy fills the 3/4 degree wide field, and the camera was oriented
along a north - south line instead of the normal South up configuration.
A few pinkish/magenta colored hydrogen clouds can be seen, however
the camera is far better at recording the individual blue features
of this enormous near by galaxy.
Processing was done
almost entirely in PixInsight, with some minor touch up in Photoshop
