Frank....
I'm not a PC person so don't take this personally....
Your data capture is great, infact I am amazed how good it is given the significant mass of your scope and not so big mount. Kudos to the G-11 for sure
Processing... sucks a little. I have no hard and fast rules, other than a warm human eye can sense a vast dynamic range and this is what I try to replicate in images. NGC2070 is a bit like M42 ie. vast dynamic range and needs much gamma stretching to show all the information in the digital data.
Stick with it...you are have the potential to be one of the best astro-imagers in Oz.
