6. If the fine height adjustment ring can’t be
turned anymore in a given direction, you will
have to turn it back to the middle and
readjust to your target by loosening the
height knob. Then you can use the fine
adjustment ring again.
7. For optimal viewing, do not touch your
telescope when looking through it.
8. Start viewing any given target at the lowest
possible magnification (the eyepiece with the
greatest focal length) and increase it to the
extent that your target permits. You will have
to refocus every time you change the
eyepiece.
9. If you watch an astronomical target for a
long time, you will notice that it gradually
moves out of the field of view. Turn the fine
height adjustment ring and loosen the tilt
knob to swivel the telescope horizontally
until your target is once again in the middle
of your visual field.
10. You will notice that you will see more and
more details in the target the longer you
practice.
DID YOU KNOW?
When you look through the telescope,
you will see how the brighter stars will
flicker and change color. This is a result
of Earth’s atmosphere. You probably
already know the same effect from hot
summer days when the air shimmers
above a hot road’s surface. With the
Moon and the planets, too, you can see
this kind of shimmering. The image in
the telescope may get sharper, and
then become blurrier again.
Sometimes, Earth’s atmosphere is very
calm for a few seconds or minutes.
When that happens, you will see the
target very clearly and sharply.

If the Moon looks too bright w
hen you look
through the telescope, whic
h may happen if
it’s close to full, screw the M
oon filter into
the front opening of the eye

soften the light.
