In this video, I process narrow-band data of the IC 1805 Heart Nebula in PixInsight and Adobe Photoshop. I also create an RGB stars layer from the narrow band data using pixel math in PixInsight. The data was collected with the ZWO ASI 1600MM Pro and a William Optics Fluorostar 110 telescope from a beautiful, dark location along the South Coast of Sweden.
Pixel Math Formula
Red: 0.4 * HA + 0.6 * SII
