naked eye and a worthwhile object for telescopes of all types and sizes.

The nebula consists of a gigantic cloud of hydrogen gas with a diameter of

hundreds of light years.

Constellation Lyra: The Ring Nebula (M 57)

Right Ascension: 18

(hours : minutes)

Declination: +33° 02'

(Degrees : minutes)

Distance: 2,412 light years from Earth

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 probably comprised of a ring (torus) of brightly shining material that sur-

rounds 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.

Constellation Vulpecula (Little Fox):

The Dumbbell Nebula (M 27)

Right Ascension: 19

(hours : minutes)

Declination: +22° 43' (Degrees : minutes)

Distance: 1,360 light years from Earth

The Dumbbell Nebula (M 27) was the first planetary nebula ever discov-

ered. On 12 July 1764, Charles Messier discovered this new and fascinat-

ing 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 micro-

fibre 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

transportation packaging. The batteries should be removed from the unit if it

has not been used for a long time.
