This is IC 1795, an emission nebula located approximately 6000 light-years away in the constellation of Cassiopeia. It covers a field of about 20 minutes of arc, or approximately 70 light years across.
At approximately 6000 light-years away from us, this complex extends across the Perseus arm of our Galaxy, the Milky Way. IC 1795 is a part of the large nebula complex of star forming regions that lie at the edge of a large molecular cloud.
Not far from the famous Double Cluster in Perseus, IC 1795 is easy to see and is in a very rich environment with IC 1805 (the Heart Nebula), IC 1848, and many open clusters.
This image was created by adopting the Hubble false-colour palette for mapping narrowband emissions from sulphur, hydrogen and oxygen atoms to the red, green and blue channels respectively.
Imaged over two night, this image comprises of over 7hrs of exposures, not including the calibration frames. Conditions were mixed, with many exposures being affected by cloud and mist. Stacked in PixIsight with each exposure being weighted according to its overall quality. Processed in PixInsight and Photoshop.
