the Ring Nebula from the side, it would look like
the Dumbbell Nebula (M27). With this object,
we're looking directly at the pole of the nebula.

The Dumbbell Nebula (M 27) in Fox was the first
planetary nebula ever discovered. On July 12,
1764, Charles Messier discovered this new and
fascinating class of objects. We see this object
almost directly from its equatorial plane. If you
could see the Dumbbell Nebula from one of the
poles, it would probably reveal the shape of a
ring, and we would see something very similar
to what we know from the Ring Nebula (M 57).
In reasonably good weather, we can see this ob-
ject well even with small magnifications.
