M16 and NGC 6604 H-alpha widefield

I don’t usually post monochromatic images, but this is a nice example of how wide the view is with the STL-11000M through the FSQ-106ED (530 mm focal length).  Not only does the Eagle Nebula, M16, fit in the field, but the entire area of nebulosity around NGC 6604 fits as well.  It makes me wish I lived further south so I could spend more time on the Sagittarius/Serpens area of the sky.  It was all I could do to capture 3h 20 min of exposure time from here in NJ.
