Description

This is still a work in progress, but I wanted to post it anyway. One of the issues I have with it is that the only luminance data I have is somewhat out of focus. To deal with that I used the deconvolution process in PixInsight and went a bit heavy on the sharpening.

I'm planning on adding more data—specifically some 15 minute luminance subs. Hopefully when I acquire more luminance frames they come out sharper 🙂
