Description

I've been struggling to get the Ha (Gold color) to show in the attached image since Dec 17th.  Every thing I previously tried left the red sulfur color dominating the ring around the blue Oxygen center.   I was having trouble producing a mask that would just cover part of the red area surrounding the blue central area.  Today, I finally found a way.  I extracted the R,G, and B color channels from the color image. Then I tried subtracting channels from each other to see if the result had the correct shape.  Subtracting the blue channel from the red channel produced the narrow C shape I was looking for.
