The famous Ring Nebula (M57) in the Lyra constellation is often viewed as the
prototype of a planetary nebula. It is one of the magnificent features of the
Northern Hemisphere's summer sky. Recent studies have shown that it is prob-
ably comprised of a ring (torus) of brightly shining material that surrounds the
central star (only visible with larger telescopes), and not a gas structure in the
form of a sphere or an ellipse. If you were to look at the Ring Nebula from the
side, it would look like the Dumbbell Nebula (M 27). When viewed from Earth,
we are looking directly at the pole of the nebula.

The Dumbbell Nebula (M 27) was the first planetary nebula ever discovered.
On 12 July 1764, Charles Messier discovered this new and fascinating class
of objects. We see this object almost directly from its equatorial plane. If
we could see the Dumbbell Nebula from one of its poles, we would probably
see the shape of a ring, something very similar to what we know as the Ring
Nebula (M 57). In reasonably good weather, we can see this object well, even
with low magnification.
Notes on cleaning
Before cleaning the device, disconnect it from the power supply by removing
the plug or batteries.
Clean the eyepieces and lenses only with a soft, lint-free cloth, like a microfibre
cloth. Do not apply excess pressure to the cloth to avoid scratching the lenses.
Protect the device from dust and moisture. Store it in the supplied bag or trans-
portation packaging. The batteries should be removed from the unit if it has not
been used for a long time.
