Notes
Orion will soon be gone from the sky for another season. I wanted to have a new attempt to produce a satisfactory photogrpah of the bright star-forming region around the Trapezium in the Great Orion nebula which is so bright that detail is very easily lost to over-exposure. The second challenge is to control this while simultaneously not losing signal in the much dimmer surrounding nebulosity. HDR methods are required so I used a series of 10-second exposures for the heart and 60 seconds for the surrounds which were then merged together using scripts in PixInsight. The Hydrogen Alpha was added to enhance the nebulous gas fields.
