This is one of the largest Peimbert-Costero planetaries and a nice object that should be better known!

My last observation was in 2001 using a 17.5" -- PC 22 was found at 220x (without filter) as a fairly faint oval, elongated nearly 2:1 SW-NE, ~20"x12" with a mag 13 star at the NE end and a brighter mag 12 star 1' SE. At 380x, a very faint companion is just ENE of the mag 13 star. PC 22 is interesting at high power with a relatively high surface brightness and an unusual elongation. Located 14' ENE of mag 6 SAO 105132 = QS Aquilae.

Back on 2 August 1986 I made what may be the first visual observation -- "at 220x a nice 10"-15" disc is visible, estimate V = 13.0-13.5. Appears slightly elongated with a faint star at the east end."
