Many observers think of M108 as "that galaxy near the Owl nebula" but it is an interesting object in its own right.  Located less than a degree away from M97 (the Owl), M108 is a relatively easy find.   M108 is one of the six objects added to the Messier catalog in the 20th century based on Messier's notes.
Walter Scott Houston describes M108 as a "bright strip of a spiral."  Burnham's scorns the M108 designation but does describe the galaxy while describing M97; "Just 48' to the NW the observer will notice the pale glow of the nearly edge-on spiral NGC 3556, looking like a little ghostly cigar..."  To my eye it appears really quite mottled, with lots of fuzzy, unresolved, detail.
