moons appear in different positions around the 
Jovian sky. This is sometimes called the Galilean 
dance. On any given night, you might be able to 
see the shadow of a moon on the face of Jupiter, 
see one moon eclipse another or even see a moon 
emerge from behind Jupiter’s giant disk. Drawing 
the positions of the moons each night is an excellent 
exercise for novice astronomers.

Any small telescope can see the four Galilean 
moons of Jupiter, plus a few others, but how many 
moons does Jupiter actually have?  No one knows 
for sure! Nor are we sure how many Saturn has 
either. At last count, Jupiter had over 60 moons, 
and held a small lead over Saturn. Most of these 
moons are very small and can only be seen with 
very large telescopes.

Probably the most memorable sight you will see 
in your telescope is Saturn. Although you may 
not see many features on the surface of Saturn, 
its ring structure will steal your breath away. You 
will probably be able to see a black opening in the 
rings, known as the Cassini division.

Saturn is not the only planet that has rings, but it is 
the only set of rings that can be seen with a small 
telescope. Jupiter’s rings cannot be seen from 
Earth at all—the Voyager spacecraft discovered 
the ring after it passed Jupiter and looked back at 
it. It turns out, only with the sunlight shining through 
them, can the rings be seen. Uranus and Neptune 
also have faint rings.

Optional color filters help bring out detail and 
contrast of the planets. Meade offers a line of 
inexpensive color filters.

What’s Next?  Beyond the Solar System:  Once 
you have observed our own system of planets, it’s 

time to really travel far from home and look at stars 
and other objects.

You can observe thousands of stars with your 
telescope. At first, you may think stars are just 
pinpoints of light and aren’t very interesting. But 
look again. There is much information that is 
revealed in stars.

The first thing you will notice is that not all stars are 
the same colors. See if you can find blue, orange, 
yellow, white and red stars. The color of stars 
sometimes can tell you about the age of a star and 
the temperature that they burn at.

Other stars to look for are multiple stars. Very 
often, you can find double (or binary) stars, stars 
that are very close together. These stars orbit each 
other. What do you notice about these stars?  Are 
they different colors? Does one seem brighter than 
the other?

Almost all the stars you can see in the sky are part 
of our galaxy. A galaxy is a large grouping of stars, 
containing millions or even billions of stars. Some 
galaxies form a spiral (like our galaxy, the Milky 
Way) and other galaxies look more like a large 
football and are called elliptical galaxies. There are 
many galaxies that are irregularly shaped and are 
thought to have been pulled apart because they 
passed too close to—or even through—a larger 
galaxy.

You may be able to see the Andromeda galaxy and 
several others in your telescope. They will appear 
as small, fuzzy clouds.

You will also be able to see some nebula with 
your scope. Nebula means cloud. Most nebula 
are clouds of gas. The two easiest to see in the 
Northern Hemisphere are the Orion nebula during 
the winter and the Trifid nebula during the summer. 
These are large clouds of gas in which new stars 
are being born. Some nebula are the remains 
of stars exploding. These explosions are called 
supernovas.

When you become an advanced observer you can 
look for other types of objects such as asteroids, 
planetary nebula and globular clusters. And if 
you’re lucky, every so often a bright comet appears 
in the sky, presenting an unforgettable sight.
