With Neil's [a friend in our astronomy club] help, I was able to load Photo Shop Elements, and download a terrific add-in program called Astronomy Tools for Photo Shop. It provides the ability to combine multiple and complicated Photo Shop actions into a simple 'one button' fix.

These images have a ways to go [especially M42 - not natural looking] but I can see the potential of these new tools. I'll get better at it.
