Elephant's Trunk - HST Palette
« on: 2011 September 02 22:11:05 »
Hi folks,

Below is my attempt at the Elephant's Trunk Nebula in HST Narrowband. I had great difficulty getting this image into shape... more than any other I have done. Most of my troubles originated from the weak OIII and SII signals when compared with the very strong Ha signal. When creating a LRGB composite from these signals, the HST palette creates a "very" green image.  The first set of color corrections I made used Photoshop's "Selective color" tool to tame the greens (certainly effective), but the version posted here used the PI curves module (hue) as Niall details here:  http://pixinsight.com/forum/index.php?topic=2346.0.

Comments and criticism welcome.
