Thank you for your positive feedback Mike.
You would like to see a “straight” Hubble rendition? Is there any such thing?
To me, the Hubble palette is a challenging exercise in colour manipulation. In the process, much of the useful H alpha depth and contrast is suppressed in favour of the low depth and contrast of the sulphur channel. Andy01 has a knack for building exceptional Hubble palette images. Not me. Perhaps it is easy when you have the right tools, and you know how! I’ve still got a lot to learn!
The H alpha channel has tremendous bit depth, and the sulphur channel little, even when I expose on the sulphur channel for 40 minutes. If I construct a straight Hubble palette image the result will be garish green because the H alpha green channel dominates the palette, with the sulphur red channel far too weak to prevail in the image.
Perhaps one of the leading photographers in this forum might write and post an easy to understand tutorial on how to achieve a pleasing Hubble palette result using PI.
Best wishes, Murray
