Planetary Nebulas are always beautiful to look at through a telescope.
Small but with rich colors which can be seen when photographing them.
M27 was the first planetary nebula to be discovered, by Messier 1764. |

Zoom into the nebula and increased color saturation.
You don't find many other objects around the nebula too: M27 plate solved by Astrometry. |
