Description:
Here is a 2x2 mosaic of the wonderful area of the sky in the constellation Cassiopeia towards the border with the Camelopardalis. Here, the famous Heart and Soul nebulae are very close to each other and shooting them together has always been one of my goals. Zooming in, more or less in the center, you can see a small planetary nebula (WeBo 1) rich in ionized Oxygen (blue) which stands out in the red of the ionized Hydrogen. This oval-shaped planetary is forming around a binary star system and was only discovered in 1995. 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, high-mass stars. The pair of nebulae is about 7500 light years from Earth and was 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.
