Robert Jonckheere was searching for double stars. Some of them turned out to be planetary nebulas, like J 900. They are both in his double-star catalog so I wondered if he ever realized his mistake. I looked it up and he did go back to them later with a larger instrument and discovered they were actually nebulas.
As usual, data is absent from the corners so I could maintain the north-up orientation of the object. The color is subjectively added.

North is up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
