object using the viewfinder rather than
locating with the eyepiece. Line up the
object with the viewfinder's red dot.
Look through the eyepiece: Once you have
the object lined up in the viewfinder, look
through the optical tube’s eyepiece. If you
have aligned your viewfinder, you will you
see the object in your eyepiece.
Focus: Look through the eyepiece and
practice focusing on the object you have
chosen.
Try out the slow motion adjustment controls:
Practice using the slow motion controls
(5,12) to move the telescope. These can
come in very handy, especially when you
wish to move the telescope in very small
(fine control) steps.
Observe the Moon: When you feel
comfortable with the viewfinder, the
eyepieces, and the adjustment controls, you
will be ready to try out the telescope at
night. The Moon is the best object to observe
the first time you go out at night. Pick a
night when the Moon is a crescent. No
shadows are seen during a full Moon,
making it appear flat and uninteresting.
Look for different features on the Moon. The
most obvious features are craters. In fact
you can see craters within craters. Some
craters have bright lines about them. These
are called rays and are the result of material
thrown out of the crater when it was struck
by a colliding object. The dark areas on the
Moon are called maria and are composed of
lava from the period when the Moon still had
volcanic activity. You can also see mountain
ranges and fault lines on the Moon.

TOO MUCH POWER?
Can you ever have too much power? If the type of
power you’re referring to is eyepiece magnification,
yes you can! The most common mistake of the
beginning observer is to “overpower” a telescope
by using high magnifications which the telescope’s
aperture and atmospheric conditions cannot
reasonably support. Keep in mind that a smaller,
but bright and well-resolved image is far superior
to one that is larger, but dim and poorly resolved.
Powers above 400x should be employed only under
the steadiest atmospheric conditions.
Use a neutral density filter (often called a
“moon filter”) when observing the Moon.
Neutral density filters are available from
Meade as an optional accessory and
enhance contrast to improve your
observation of lunar features.
Spend several nights observing the Moon.
Some nights, the Moon is so bright that it
makes other objects in the sky difficult to
see. These are nights that are excellent for
lunar observation.
Observe the Solar System: After observing
the Moon, you are ready to step up to the
next level of observation, the planets.
There are four planets that you can easily
observe in your telescope: Venus, Mars,
Jupiter and Saturn.
Eight planets (maybe more!) travel in a fairly
circular pattern around our Sun. Any system
of planets orbiting one or more stars is
called a solar system. Our Sun, by the way,
is a single, yellow dwarf star. It is average as
far as stars go and is a middle aged star.
Beyond the planets are clouds of comets, icy
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.
