M20 - Trifid Nebula 


Acquisition Details:

Telescope:  12.5" Ritchey-Chretien @ F6.75

Camera:  ST10-ME, CFW8

L=6x10min, binned 1x1, Median Combine w/Norm, CCDSharp 5 iterations, DDP

R=3x10min, binned 1x1, Median Combine w/Norm

G=3x10min, binned 1x1, Median Combine w/Norm

B=2x15min, binned 1x1, Median Combine w/Norm (lost 1 frame due to tracking)

Final Image Processing: Starizona's Anti-blooming filter run on all frames, DDP to RGB layer, combined luminance and RGB in Photoshop 7.0, Used Photoshop to create multiple layers to bring out the faint outer detail while preserving the core.  I created second version of the image using AIP to process the Luminance layer.  I then took the two versions and layered them in Photoshop to bring out the parts I like from each version.  So much Photoshop magic that I couldn't reproduce this exact result again if I wanted to.
