Heart Nebula
This is the Heart Nebula, also known as IC1805, captured using three narrowband filters for Hydrogen, Sulphur and Oxygen emission. This image uses the so-called "Hubble Palette", in which a false color image is constructed using a monochrome camera plus individual narrow bandwidth filters to create an RGB image. Here, the Hubble palette is "SHO" where red = sulphur, green = hydrogen, blue = oxygen.
