 | | Spiral Galaxy M108 (NGC 3556), type Sc, in Ursa Major |
 | | According to Charles Messier's hand-written preliminary and unpublished version of his catalog, M108, similar to M109, was discovered by Pierre Méchain shortly after M97 (which he had found February 16, 1781): Méchain discovered M108 3 days after M97 on February 19, 1781, and M109 on March 12, 1781. |
 | | Color photos show an even more conspicuous appearance of this should-be showpiece, which often appears in wide field and "deep spatial depth" photos together with the Owl nebula M97, which is only about 48' to the SE. |
