Description:
Here is a 4-panel mosaic in SHO rendition, for a total of 64 hours of integration, of the wonderful area of sky in the constellation of Cassiopeia, towards the border with the Camelopardalis, containing the Heart and Soul nebulae. The Soul Nebula (also known as the Embryo Nebula or IC 1848, Sh2-199 and W5) and the Heart Nebula (also known as the Running Dog or IC 1805, Sh2-190 and W4) are diffuse nebulae associated with open clusters of young, hot and high-mass stars. The pair of nebulae is about 7500 light years from Earth and they were discovered by William Herschel on November 3, 1787. The brightest part of the Heart Nebula (the so-called Fishhead) is classified separately as NGC 896, because it was the first part of the nebula to be discovered.
