StarTools v1.2

I've been playing with a new image post-processing program that I was introduced to on AstronomyForum.net. It's called StarTools http://startools.org/drupal/ and so far I have found it to be a great, fast to learn and very powerful image processing program. Since it has been raining here most of this week, I have gone back and played with a few of my images just to give it a test drive. (M20 Trifid Nebula)
