Actually, I was referring to stills #2 and #5, and I still claim that some of the stars have been lost. There are faint stars that are present in the original and missing from the processed versions. It not so much the importance of those stars, but that it would be reasonable to assume that other detail has been lost as well, however minor. That said, your color correction and contrast looks very nice.

One of the things I intend to be very careful about, is how much contrast adjustment I do. I love the look of the blacks/whites in these samples, but if that's what gave rise to the loss of stars, then I have some serious decisions to make.

You're right about #2 (that one got DeSpotted) but here's a brightened up shot #5:

I was very careful during my color correction to not crush the blacks (or burn the whites, respectively), so I'm pretty sure it's all there (I'd even say that because of the contrast correction the stars are more pronounced now). To me it's always okay to have some grain left in the darks, plus that way even fainter details won't get swallowed. I don't know on what kind of "equipment" everybody is looking at these screenshots, but I've noticed that a lot of people tend to have their screens set way too dark...
