Description

This planetary nebula mainly emits in Ha followed by OIII. Very little SII. The Ha extends far beyond the nebula with OIII remaining local to the nebula.

The Sharpless catalog is a list of 313 emission nebulae. The first edition was published in 1953 with 142 objects, and the second and final version was published by US astronomer Stewart Sharpless in 1959.

In 1953 Stewart Sharpless joined the staff of the United States Naval Observatory Flagstaff Station, where he surveyed and cataloged H II regions of the Milky Way using the images from the Palomar Mountain, CA Sky Survey.
