The galaxy has a length of 14 arc minutes and a thickness of only 1.4-minute;
you may be able to see only a simple line through scopes.
Though its apparent size is very same as that of NGC4565 in Comae Berenicis, a magnitude of NGC5907 is estimated only 11.3,
so NGC5907 shouldn't be listed in the easily visible objects with medium-sized telescopes.
The galaxy has an undeveloped central nucleus (Bulge), and it's one of characteristics of the inconspicuous galaxy.
