The Southern Owl Nebula (PLN 283+25.1, ESO 378-1) is a planetary nebula located in the constellation Hydra. The nebula lies at a distance of 2,030 light years from Earth. It is named so because of its resemblance to the Owl Nebula in Ursa Major. [2] The nebula is notably symmetric, round, and has a diameter of approximately four light-years ...
The bright planetary nebula Owl Nebula (M97) can be found along the bottom of the bowl of the Big Dipper. M81 is a nearly face-on spiral galaxy 11.8 million light-years from Earth. Like most spiral galaxies, it has a core made up of old stars, with arms filled with young stars and nebulae.
The catalogue includes most of the astronomical deep-sky objects that can be easily observed from Earth's Northern Hemisphere; many Messier objects are popular targets for amateur astronomers. [ 2 ] A preliminary version of the catalogue first appeared in 1774 in the Memoirs of the French Academy of Sciences for the year 1771.
NGC 457 (also designated Caldwell 13, and known as the Dragonfly Cluster, E.T. Cluster, Owl Cluster, Kachina Doll Cluster or Phi Cassiopeiae Cluster) [2] is an open star cluster in the constellation Cassiopeia.

Messier 108 (also known as NGC 3556, nicknamed the Surfboard Galaxy [6]) is a barred spiral galaxy about 46 million light-years away from Earth [3] [7] in the northern constellation Ursa Major. It was discovered by Pierre Méchain in 1781 or 1782. [8] From the Earth, this galaxy is seen almost edge-on.
