Description

I tried a different processing work flow with this galaxy. I did not use the HDRMultiscaleTransform to bring out the contrast - I found this produced an artificial image. Instead, I used LocalHistogramEqualization to do the same thing.

Finally, I used ColourSaturation to bring out the blue and red more fully.

The second image has about 3 hours of Ha data added (just for Andrew...)
