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.

Barlow lens: You can also change
magnification by using a Barlow lens. The
Barlow lens doubles the power of your
telescope. See Fig. 6.
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
telescopic field of view. This movement is
caused by the rotation of the Earth and
makes an object move through the tele-
scope’s field of view. To keep astronomical

STAR CHARTS
Star charts and planispheres are useful for a variety of
reasons. In particular, they are a great aid in planning a
night of celestial viewing.
A wide variety of star charts are available in books, in
magazines, on the internet and on CD Roms. Meade

adjustment controls. At higher powers,
astronomical objects will seem to move
through the field of view of the eyepiece
more rapidly.
Place the object to be viewed at the edge
of the field and, without touching the
telescope, watch it drift through the field to
the other side before repositioning the

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