This obscure but easy to locate planetary can be found in Hydra. The magnitude 7.2 SAO 137026 is virtually superimposed on Abel 33's south-western edge, says Steve Gottlieb. A 17.5" scope and O III filter together show signs of annularity in this object. The planetary was discovered in 1964 by George Abell as he searched through the POSS plates.
