M108 (NGC 3556) in Ursa Major
Sketch and text by Kiminori Ikebe translated by Eiji Kato
This is a galaxy near M97, the Owl Nebula. It is quite bright and large with a mottled surface brightness hinting at some structures. It is has a narrow elongated shape, but unlike edge-on galaxies, it does not have a central condensation or sharply defined outline. It seems to be split into three regions. There is a small isolated area at the western end of the galaxy. The center of the galaxy is elongated and the eastern part is faint and diffuse. There is a star on the western side.
