Messier 108 - NGC3556


M108 is a quite impressive galaxy. We see M108 nearly edge on. But at enough of an angle to see plenty of detail in the galaxy's disk. It shows obvious irregular dust arms with lots of intricate detail. There is no obvious core however.


M108 was discovered by Pierre Méchain in 1781


Not far from M108 one can also find the planetary nebula M97. Somewhat to the South-East
