Discovered by Pierre Méchain in 1781.

The nearly edge-on galaxy M108 appears to have no bulge and no pronounced core at all, it is just a detail-rich mottled disk with heavy obscuration along the major axis, with few H II regions and young star clusters exposed against the chaotic background -- in a word: "Very Dusty". There's little evidence for a well-defined spiral pattern in this Sc galaxy, which is receding at 772 km/sec. According to Brent Tully, it is about 45 million light years distant, and a member of the Ursa Major cloud, a loose agglomeration of galaxies.

M108 is quite faint and it looks very similar to M82 in 8" telescope.
