NGC2403 (reprocessed with Ha)

This was the first image incorporating data from my new 3nm Ha filter (3 x 1800s) and was a bit of an experiment.  The image is identical to the other NGC2403 apart from the incorporation of Ha data.  The Ha data was added by blending the Red channel of the original (RGB) OSC image with the Ha image using PS Lighten.  The Ha data was only applied to the galaxy core since I was concerned about unbalancing the star colours. Incorporating Ha data in this way yields the Ha as  an "electric pink" colour in the final image. Since this be very dominating, I reduced the effect.  Overall, I prefer the result to the non-Ha version.
