Title: NGC 6888 and Soap Bubble Full Image

Description: I wasn't happy with the stars in the first version which caused me to crop the image. I went back to the Luminance and instead of using lighten to add starless Ha and O3 I used add in PS. To my eye it made a big difference to the star field...

Description: Inspired by a few u[dates I've seen here on Astrobin I went back to this data and worked on bringing out more of the O3. I used SPCC on my RGB data to set the background and then blended in Ha and O3 to red and blue. I used a combined Ha/O3 layer for luminance.

Description: I wasn't ha[[y with the stars on the previous revision. I realized that I'd used the stars from my RGB data without luminance and they had significant halos. So I used the Ha stars as a luminance layer and I think it helped. Anyway I'm done for now!
