The Flame Nebula, NGC 2024 is located near the left star in Orion's belt.   This composite image is made up a lot of raw images, the most I have combined yet, 25 images of  LRGB totaling 32:9:9:9 minutes.  The resulting image shows great detail in the structure of the nebula.   The ghostly blue semi-circle at the bottom is the star Alnitak (the belt star), which is just outside of the field of view and extremely bright.  This set of images was taken on Febuary 11, 2004.
