NGC 1535 is a beautiful bright planetary nebula in Eridanus. It clearly shows a shelled structure very similar to the Eskimo Nebula (NGC 2392). These little planetary nebula make fine visual targets and are among the few deepsky objects that show a beautiful blue color.

NGC 1535 is currently well placed in the south during the early evening.
