Description

The Rosette Nebula, imaged in RGB with Ha for luminance.

Did a linear fit on the RGB against B prior to combining, to focus on the blue component.

The RGB stars were quite bloated compared to the Ha stars. Had to knock them down quite a bit with MorphologicalTransform before doing the LRGB combination in order to reduce halos.
