GIMP-ing the Great Orion Nebula etc.

[Macavity]

As a Video Atronomer (by choice) and cheap skate (unfortunately!) 

I find myself having to "translate" Photoshop image methods to GIMP. 

With the Great Orion Nebula currently in view I was looking for a

way of extending the contrast of my humble offerings. Then I came

across this script - Generic "Contrast Blending" and all that?

I have only run it with "simulated data" but it works / looks useful?

Hmm so would you run this with images that have been stretched differently or use ones that have been exposed differently?

Does it work in 16 bit?

No tests yet. I have a feeling that it would require different *exposures*.

Which I sense also requires a bit of thought or experiment?

My initial fiddlings were with the same image, differently stretched etc.

I EVER hear rumours that GIMP in "eight bit"? On the other hand, so are

my Video Astronomy images. Which also make things slightly trickier...

Well there is a 16 bit version of gimp available, I'm just not sure if this plugin would work in it.
