M42 H-alpha High Dynamic Range composite processing with StarTools 1.3.200 Release Candidate (download at http://startools.org)

*** Best viewed in HD ***

In this video we process a magnificent multi-exposure length Hydrogen-alpha data set that was so graciously donated to the public domain by Josh Lake of the Olmsetd Observatory at Pomfret School.

We process two exposure lengths independently, and combine them into a high dynamic range image. After combining, we modify the presentation of the image to match the data provider's personal taste by scaling down the image and performing some delicate sharpening.

The final result can be found here; http://startools.org/download/Tutoria...

StarTools is a not-for-profit endeavour with the aim of opening up the field high quality deep space photography for anyone, no matter your gear, no matter your budget.

StarTools sets itself apart from traditional (astronomical) image processing software by focusing on ease of use and active monitoring of the user's processing steps. StarTools uses information gleaned from the latter to achieve better results in less time, while providing useful hints and tips, and protecting your data from clipping, overcooking, or sequence related mishaps.
