Object Info: The considerably bright, very large edge-on spiral NGC 4565 is 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. NGC 4565 is about 31 million light years distant and has 90.000 light years diameter and it's visual brightness is 9.6 (mag).
