Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Historical observations

NGC/IC Dreyer (1888, 1895, 1908)

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"

Modern observations


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.
