Imaged from Death Valley. Compare to my image of M8 using the same gear except captured by an Olympus OM-1N on Lumicon Hypered Fuji 400 film back in 1984.

Many thanks to Roger Clark for his advice and assistance with rnc-color stretch. Also, much thanks to Wei-Hao Wang for his forum posting on asin stretching. It was very helpful in the processing of this image.

I very much enjoy this article by Roger Clark regarding the color in this and other astronomical objects.
