NGC4565 Needle Galaxy presents a classic view on an edge-on
galaxy. It lies about 40 million light-years away.
Stretching about 200,000 light-years in length, it is almost
the same size as the M31 Andromeda Galaxy, but is actually
brighter. Galaxy NGC4562 is easily visible at the top-left of the
image, galaxy IC3571 is the tiny smudge straight below the center of
the Needle Galaxy, and galaxy IC3546 is at the bottom-left
edge. North is at the bottom.
