The image was shot through narrowband filters, and maps Sulfur 2, Hydrogen Alpha and Oxygen 3 to R, G and B respectively, comprising approximately 24 hours of 20-minute sub-exposures. Additionally about 90 minutes of short RGB exposures account for truer star colors overlaid on the image. Processed using PixInsight and Photoshop.
