Owl Nebula

The Owl Nebula, also known as Messier Object 97, was discovered by Pierre Mechain in 1781. This Nebula is gets its name due to the "eyes" on an owl when viewed through a large microscope.The Owl Nebula goes back to around 1848 when Lord Rosse used it in his drawing. Charles Messier also mention two other nebulous objects that he and Mechain have seen in his personal copy, as well as descriptions in pre-print version, from this weknow that he observed M108 and M109. This target when given a description has a right ascension of 11:14:80, declination of +55:01, distance of 2.6 (kly), 9.9 visual brightness, and 3.4 by 3.3 apparent dimension.

The description of the Owl Nebula itself looks like a round cluster of stars with 3 bright "triangle" spots (This is where it gets its Owl name from). This Nebula appears to have redish spots on the top left corner. The structure of the colors that are seen are redish, green, teal, brown, and almost grayish color.The approximate angular size is 165 pixels across. The size in arcminutes is 3.60. The linear size of this object is .0027 light-years.
