Always improving. I managed to get tight focus across all my filters. The moonlite focuser is dialed in, and the automatic meridian flip in SGP is configured now and working wonders. Very nice!

I was being careful with NR and tedious with DBE values to remove gradients. I still need to figure out how to get my star colors under control after a saturation curves boost. I pushed it to the limits and getting some color rings and slightly odd colors on some stars. I will focus my attention to this on my next integration.
