M42 simple "HDR"

[smokey688i]

Wanted to share my result of a quick "HDR" image of M42 and the Running Man. This is only 5x 120s lights (plus darks/flats/dark flats), shot at 400ISO with my Nikon D5100, CCDT67 reducer, and 6" GSO RC. Encountered some guiding issues so didn't get as many subs as I would have liked. I processed the DSS stack output twice in startools, once to focus on the fainter nebulosity, and a second time focusing on the core - then I combined these in the Layer module with a simple mask around the core of Orion. I think this really shows how useful lower ISOs can be - IMHO, not a bad HDR composition for using only one exposure length! Now need to take even longer subs to bring out the fainter nebulosity even more...

Step 2...added several 240s frames in and combined the previous images for the core. A few aircraft decided to fly by the running man in no less than four of the subs, so more data to be added later.
