This is my attempt to image the Rosette Nebula using the Hubble pallet. I really stuggled to get the colors to match my vision for this object. I tried some different pallets suggested by others but ended up using the straight Hubble color mapping. I then learned to use the PixInsight curves transformation in hue mode to affect some subtle shifts in color balance. The final image does what I hoped for; it uses color to emphasize the different structures in this fantastic subject.

I finished processing this image last night. It looked much greener this morning. So, here's another version with one more light pass of SCNR to remove the green tint.
