Taken with a ZWO ASI120MM camera and Optolong CCD RGB filters and a Celestron Edge HD 925 telescope from my backyard in Long Beach, CA.
The best 35% of frames from SER videos with each of the filters were stacked in AutoStakkert. This created 6 images in each of the three color filters. Those images were sharpened in PixInsight. All images with the same color filter were derotated and combined in WinJUPOS, then the R, G, and B stacks were derotated and combined to create the color image. I used Registax to get the color balance right, that did some small final touches in Photoshop.
Thank you to Damian Peach for making processing tutorials available through his Patreon channel. I was really struggling with getting Saturn to look right before viewing those.
