NGC4565 is one of the brightest and largest galaxies without Messier's numbers scattered around the constellation of Coma Berenices.
The galaxy is fairly popular one because it's often quoted as a very typical example of the "edge-on" galaxy.
This edge-on galaxy is about 45 million light years away and has an apparent size in the thickness-direction of only 2 arc minutes, but has a length of more 15 arc minutes,
equivalent to the half of an apparent diameter of full-moon.
It might be easy to search the galaxy with the binoculars; you can recognize it as a narrow line in the conditioned sky.
You will be able to enjoy the galaxy looks like the front-view of a plane with scopes.
Though this picture shows you a dark lane crossing, you might need a bit larger scope to see the lane with naked-eyes.
The galaxy has a long-short ratio of about 14:1. Almost all of typical galaxies have such a thin figure, of course including our Galaxy.
