Rosette, (HaR)GB, rework… a LOT of rework!

Having been given “the day off” from looking after our new arrival, I have just spent the entire day doing astro related stuff… its been awesome 🙂

Anyway, one of the things on my to-do list was to spend to more time processing my Rosette data from a while back, taking on board the various comments that have been made about it. Just finished 4 hours of playing with this, and included the following improvements:

– better contrast in the rosette itself
– less “salmon pink”, more red
– removed the cyan halos aorund the stars in the left of the image
– added a tiny amount of the Ha into the blue channel (about 12% looked about right)

Also took on board some of the items covered at the SGL Imaging day, specifically the keeping color saturation without losing detail, and the Shadow/Highlight tool, plus managed to get a good star reduction on the image.

So, here we go….
