Helix_Nebula_HOO

Another bicolor HOO (Natural Color Blend) for one of my favorite targets ever: the Helix Nebula, also know as the "Eye of God".

HOO palette is created by using narrowband filters to acquire data and assigning the data captured to one of the red, green and blue colors in an RGB image. For this palette the Hydrogen Alpha is assigned to Red, a mix of Oxygen and Hydrogen Alpha to Green and Oxygen to Blue.
