NGC 4565
22/10/08
The 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. NGC 4565 is about 31 million light years away from the Milkyway galaxy.
The Ring Nebula

The
“Ring Nebula”
is located in the northern constellation of Lyra, and also catalogued as Messier 57, M57 or NGC 6720. It is one of the most prominent examples of the deep-sky objects called planetary nebulae (singular, planetary nebula), often abbreviated by astronomers as simply planetaries or PN.
M81
07/10/08
Messier 81 (M81, NGC 3031) in Ursa Major is an easy target for amateur astronomers. It has a little dark matter, as its rotation curve was found to fall off in the outer regions; this is in contrast to many galaxies for which the rotation curve increases outward.
