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
same size as they look in your eyepiece. You
will see that the moons are in a different
position every night. As you get better at
drawing, try more challenging sights, like a
crater system on the moon or even a nebula.

Go your library or check out the internet for
more information about astronomy. Learn
about the basics:  light years, orbits, star
colors, how stars and planets are formed,
red shift, the big bang, what are the different
kinds of nebula, what are comets, asteroids
and meteors and what is a black hole. The
more you learn about astronomy, the more
fun, and the more rewarding your telescope
will become.

SOME OBSERVING TIPS

Eyepieces:  Always begin your observations
using the 25mm low-power eyepiece. The
25mm eyepiece delivers a bright,  wide field
of view and is the best to use for most
viewing conditions. Use the high-power 9mm
eyepiece to view details when observing the

Moon and planets. If the image become
fuzzy, switch back down to a lower
power. Changing eyepieces changes the
power or magnification of your
telescope.

By the way, you might have noticed
something strange when you looked through
your eyepiece. Although the image is right-
side up, it is reversed. That means reading
words can be a problem. But it has no affect
on astronomical objects. If you wish to have
a fully corrected image, check out Meade’s
optional Erecting Prism in the Optional
Accessory section.

Meade offers a complete line of eyepieces
for your telescope. Most astronomers have
four or five low-power and high power
eyepieces to view different objects and to
cope with different viewing conditions.

Objects move in the eyepiece:  If you are
observing an astronomical object (the Moon,
a planet, star, etc.) you will notice that the
object will begin to move slowly through the

damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
