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. Only
very large telescope will reveal spiral or
elliptical details.
You will also be able to see some nebulas
with your scope. Nebula means cloud. Most
nebulas are clouds of gas. The two easiest to
see in the Northern Hemisphere are the
Orion nebula during the winter and the
Triffid nebula during the summer. These are
large clouds of gas in which new stars are
being born. Some nebulas 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.
The more you learn about objects in the sky,
the more you will learn to appreciate the
sights you see in your telescope. Start a
notebook and write down the observations
you make each night. Note the time and
the date.
Use a compass to make a circle, or trace
around the lid of a jar. Draw what you see in
your eyepiece inside the circle. The best
exercise for drawing is to observe the moons
of Jupiter every night or so. Try to make
Jupiter and the moons approximately the
