Data: mag 6.4  size 7.0'
Position: RA 18:18.8  DEC -13:47
Description:
Could easily make out 35-40 stars in the cluster.  The brightest are two yellow
stars, resembling a double right below the dark pillars.  With a UHC filter the
Eagle shape is obvious.  The pillars are easily visible as dark areas and 
occasionally become clear enough to honestly see the familiar shapes in all those
great long exposures. But they are only visible with averted vision.  Direct vision can only tell that there is slightly less nebulosity.  Overall a real beauty.
