I updated to the latest version.
That really was a very helpful video - I'll be referring back to that. Attached is a jpg of where I ended up after trying to replicate what you've done (first full run-through).
There were a couple of things you wondered about during the video...
The noise is from my backyard sky - I think I'm in an Orange zone.
The image is a dss stack (save as, don't apply), from my Nikon D5300 DSLR, so that explains the size.
The green in some of the stars may be from my scope. It's an old (2002) Stellarvue 102EDT. A really good scope for its time, but not an APO, and I think that mostly shows up in both the size, and internal color of the stars.
If I keep at it, I think most of what you've done will sink in eventually

Thanks again for all your help!
