Reprocessed Lagoon Nebula masked.

Hi all
I wasnt fully happy with my previous Lagoon shot, not being able to capture the full dynamic range, so I tried the masking method, processing the original image in Photoshop as a dark image, showing only the brighter parts and Hourglass nebula , and also a bright image showing all the outer parts while burning out the brighter parts, then masking them together in Photoshop to a single image.
2x5 mins ISO 1600, with UHCS and UV/IR filter, 10 inch F5.6 newtonian
