On this version I tried bringing out more of the O3 "blue" area around the bubble. Mike

I'm curious, what did you do to enhance the O3 emissions?

 

Thanks, and this is a great image!

Thanks Gabe! I made a Range mask and a star mask. Subtracted the star mask from the range mask using Pixel Math. Then lowered the red channel and increase the blue. Also had to increase the green channel a bit to get rid of the nasty purple.

Thanks Jim.  10.5 hours on this dim target really helped!

Interesting! I'll have to try that on my Bubble data when I get some free time.
