I made a video walking through the entire process to show how much potential is hiding in the data you probably already have. It covers my main steps in Siril, Photoshop and SETI Astro Suite from the initial background extraction and color calibration to using modern tools like Cosmic Clarity and Graxpert to really make the details pop.
My hope is to show that focusing on your post-processing technique is often the most effective upgrade you can make. Happy to answer any questions about the workflow!
