Yes, I have. It’s particularly difficult as I live in a place with a very low sky-fog limit and a lot of light pollution… and I’m just not adept at using the curve tools. This is why I’d like an astrophotography-specific tutorial for PL. I’ve watched other tutorials, but there’s always some Photoshop talk that ensues which I don’t know how or if it even can be translated to PL. (I do realize they are not directly competing products).
Perhaps you can see in that that there’s also a bit of research embedded in this question, as I’m trying to see if it’s worth upgrading my PL or moving onto another tool for astrophotography. Having a PL-specific tutorial on this would do both upping my astrophotography post-processing skills and learning that for PL.
