Hi Astroman,
The only input from me is programing CCDAutopilot3 each session (15 mins), once that is done, each night I hit the go button to repeat everything until I have the correct total exposure time (5 mins or less).
I've just changed to the screen showing you how I setup the light exposures.
Having said that you need a highly tuned system in order to pull this off. I spent about 8 week setting it all up and ironing out the bugs.
Most of the well know amature astro imager all use CCDAP3.

My LRGB exposure are short, if I shoot narrowband my sub exposures are normally 1 hour long.
Here is the Clear (luminance) images, stack and DPP from last night efforts. Reduced by 50%
Cheers,
