This is an image I have been wanting to get for a long time.  It's difficult to capture from my home for a variety of reasons.  So spending a night near Natural Bridges National Monument, at some of the darkest skies in the USA, was the perfect opportunity to capture the Trifid.  The skies are so dark that even with only 4 hours of data the image is relatively noise free.
