Description

This is my first attempt at compositing short and long exposures to resolve the trapezium.  I used 300 second exposures for the surrounding nebulosity and 5 second exposures for the core.  I originally tried 10 sec but even that was too long.  The 300 second exposures over did the stars but did bring out some nebulosity.  I am not completely happy with the result but it is my best effort to date.  This is definitely a challenging object.
