This right here is a *masterpiece* of processing by none other than Jason Major: Rhea and Epithemeus in front of Saturn 😍

Although you're probably already like "duh it's gorgeous, yeah it's a masterpiece!", it's more than that: those are moons, and moons are in constant motion. Color images are produced by combining images taken in the red, green, and blue filters.

Each image is taken at slightly different times, so the moons will be in different positions in each shot. If you just superimpose them, you'll get something that doesn't have sharp edges like you see here.

This requires the expertise that I admire in images taken by people who've inspired me to start doing this, like @JPMajor. I was never able to get it right. But I'll keep trying, and continue to admire the images like these that experts like Jason process!

Also, *Epimetheus 😑

*not taken, but processed.
