Description

Mixed 25% Ha into the Red channel and 12% Ha into the Blue.

Ran HaR-G-HaB through eXcalibrator to get correct star color balance.

Then converted the HaR-G-HaB to Lum and blended it in 25% with the Ha.

But still can't quite get the color balance correct. R, G, and B all have bad background gradients that should be removed before running them through eXcalibrator but I don't have a good way to do this at the FITS level yet (no PixInsight or MaximDL here; failed completely with Iris and StarTools).
