IC63 by Rune Matthijssens
I used the RGB images to create a RGB image and I took the Ha images to create a HARGB image. Personally I like the RGB more.
This faint nebula is located in Cassiopeia. It has an apparent magnitude of +10 and an extremely low surface brightness. It surrounds a star that is partly unstable and known as a "shell star". It has a magnitude of +2.15. wich makes it the brightest star in Cassiopeia. The nebula is estimated to be 3 ly from the star. Altough that IC63 is closer to the star then it's brother nextdoor (IC59). As a result it appears mostly red due to the dominance of the Ha emmision. It's is then a reflection and an emmision nebula. Wich means that Hydrogen is ionised and gas is reflecting light of the star. It is estimated to be 650 ly away from Earth with a radius of +- 1 ly.
