This is a narrowband take on the Cone and Foxfur nebulae. I blended Ha with OIII for the Blue and a little Ha with the SII for red. The two are mixed for Green and the Ha is used straight for Luminance. By no means a representation of the correct colors!

52 Ha, 49 OIII, 31 SII all 10 minute 2x2 subs (a binning decision I regret).
