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.

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
you may not see many features on the
surface of Saturn, its ring structure will
steal your breath away. You will prob-
ably be able to see a black opening in
the rings, known as the Cassini band.
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.
