As the other thread has discussions other than imaging, I'll open another with this image.
It's the same field as before with more Ha data (4 hours in total). I processed this one to bring out the detail in the nebulosity, trying hard to retain the colour from the RGB.
After several attempts using two different methods of data combination I achieved about as good as I can do today. The data looks to be background clipped, this is an artifact of the LP removal procedure. I like it as it really brings out the faint nebulosity.
