It was discovered by Delisle Stewart on photographic plates taken with the 24" Bruce refractor at the Arequipa station of Harvard College Observatory. He described it in the NGC as "very faint, very small, round"
Shapley, H. (1936) Five planetary nebulae and a globular cluster. Harvard Obs. Bull., No. 902, 26-27.
A photographic survey of bright southern planetary nebulae. M.N.R.A.S., 110(5), 429-439.
This faint planetary nebula lies 2 South of 6th magnitude Nu Pavonis. It lies less than one degree away from the very similar planetary NGC 6630. You will need a 12" or larger telescope on a very dark night to spot this dim 15th magnitude object. It shows as a faint circular disc 19" across, quite like an out of focus star at high magnification. Because of its very low surface brightness, it shows no colour and appears a pale grey.
16-inch f/10 SCT (127x, 290x)
Lies 22' towards the east of NGC 6630, but not sure about the sighting.
