M16 Eagle Nebula, an emission nebula in the constellation Serpens

Also called NGC 6611

The short 2 minute exposures were taken instead of the usual 5 to 15 minutes in order to minimize bright star blooming on the raw images.

This is a redo of a previous image taken in 2008 using an SBIG ST-2000XM CCD.
