Hello Harry,
I wish I could think of a face saving answer to your question! It's amazing how one thing leads to another. I started out by getting acquainted with the Astro Tortilla wrapper that involves, among other things plate solving with astrometry.com.
Thanks for pointing me back to good old PI to further my education on the subject.
It's back to school for me, trying to unravel the thread you pointed me to. How about a video tutorial on the subject? (In your spare time, of course.)
Dave
