The real value in what you provided has been the ability to see exactly the effect of flats, and bias, and darks and to try it out multiple ways and to see the image improve with each addition.

And I might add, for others trying this, I find that DSS is good for one conversion after launching. If I try to clear the files, and do another conversion, it doesn't succeed. But if I completely close it down and relaunch, it converts the next batch just fine.

But until I retire in 3 months, I just don't have the time to be going out at night to do this very often. Not with an alarm set to go off at 5AM.

And one last thing to buy now before retirement is a mono CCD.

The camera has been nice, but the CCD should outperform it.
