This is an integration using Astro Pixel Processor of this dataset and the larger SPA-2-CCD HaLRGB dataset. Specifically, processed using APP, PixInsight with GraXpert, Blur, Noise, and StarXTerminator, ContinuumSubtractionUtilitty, ImageBlend, GHS, and Affinity Photo 2. Note that I did not use SPCC because it does not seem to handle color correction well if the optical hardware cannot be precisely specified.
