OBJECT DESCRIPTION

 

NGC 6509 is a very small blue planetary nebula located in the constelation of Delphinus. It is surounded by a nice star filed (see wide field picture). Discovered in 1782 by William Herschel, this planetary nebula is accessible in a 6-inch scope, although it is in the larger instruments that it really shines. It is not a good target for southern observers because it is too low from the horizon, but is always good to grab some gems from the north hemisphere. The seeing was very good that night although some clouds pass through very fast and I had to interrupt the session for some minutes.
