This nebula was first discovered by the astronomer Stewart  Sharpless in 1959 and included it in his catalogue of HII regions as Sh2-200.

In 1983 Sh2-200 was included in the HDW catalogue (HWD 2) by astronomers Herbert  Hartl, Johann Dengel and Ronald Weinberger as a possible planetary nebula.

In 1987, using narrow band imagining, Herbert Hartl and Ronald Weinberger detected a large faint outer halo extending further than the central shell.

In 2017 it was confirmend to be a planetary nebula when spectra was taken as part of professional observations.

The popular name is the Bearclaw Nebula.
