Heart Nebula

02 Dec 2025

This is the Heart Nebula also known as the Running Dog Nebula, Sharpless 2-190). It’s an emission nebula, 7,500 light-years (2,300 pc) away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This was taken using SHO filters on my mono IMX492 camera & processed in Siril and Gimp
