SEDS description;
Discovered by William Herschel in 1785.
The considerably bright, very large edge-on spiral NGC 4565 is another showpiece for amteurs, and often used in textbooks, as it is assumed that its view may resemble that of our own Milky Way, seen from outside from a place situated near its galactic equatorial plane. According to R. Brent Tully, NGC 4565 is about 31 million light years distant.
