| Description | Discovered by Messier himself (#13), recorded on July 12, 1764, "it appears of oval shape, & it contains no star". <--> This is a huge, very bright planetary nebula: the first in the Messier Catalog and possibly the first ever recorded. Of course, there IS a tiny central star, a white dwarf, which shed the material now ionized as the planetary disk as well as lanes of red dust within the envelope. Field Stars are misshapen arguing for wind or poor seeing. |
