Note: I forgot to cover noise reduction, and the best way to reduce noise is always to collect more data to improve SNR (signal to noise ratio). Here I was using only 48 min. of data and 2-3 hours minimum would have worked much better for an object like this. However, if you want to use noise reduction in processing, both GraXpert and Seti Astro's Cosmic Clarity have AI-based tools for noise reduction which work well and should be straight-forward to add to the tutorial.
