Great images Gary, I like the M16-M17 one. The nebula on the right of M16 is in NGC 6604. I think it is LBN 72 not Sh2 53. It is very faintly visible in a 10" or 12" with a UHC filter.

The dark nebula in CrA should be called Dunlop 559, it was found by him in 1826. It is usually called Bernes 157 but he didn't catalogue it until 1977.
