NGC 896 is an emission nebula located in Cassiopeia about 7500 light years away. It is also the brightest part of the Heart Nebula (IC 1805) but has a separate classification, since it was the first part of the nebula to be discovered.  The dominant red colour arises from hydrogen line photon emissions created by intense ultraviolet emissions from nearby stars. It is a star forming region and also home to many dark lanes created by interstellar gas. Some very bright blue stars compete in the nebula illumination, resulting in a blue/red cast in certain parts of the image.

The LRGB image has an Ha blend into both the red and lum channel and was taken with my Esprit 150. It represents 18.5 hours integration time.
