Hi David, Very nice. Much better than I was able to do. I do have Photoshop and fits liberator. What I don't have is the patience to figure out how to use them to their full potential. :) Clear skies, patrick On 14 Sep 2010, at 09:22, David Rankin wrote:
Patrick,
Do you have photoshop? There is a neat plugin called fits liberator that handles these fits files. I pulled it into photoshop using that plugin, then did no white or black clipping. I then got it into the photoshop work environment and just used the levels and curves tools to get the data out. The blacks were already pretty clipped, so in the levels tool, I used the middle slider and pulled it left to get the fainter stuff out. I never, ever, pull in the right slider as that clips the star data and blows out faint stuff quick. I then use the curves to add contrast and stretch a bit more.

That is my stretching techniques. If you put it in 702p and full screen its easy to follow.
Here it is processed:

Not sure if that is any better than what you were able to get out.
Cheers, and very cool image :)
