observed.
Vibrations:
Avoid touching the eyepiece
while observing through the telescope.
Vibrations resulting from such contact will
cause the image to move. Avoid observing
sites
where
vibrations
cause
movement (for example, near railroad tracks).
Viewing from the upper floors of a building
may also cause image movement.
Let your eyes "dark-adapt:" Allow five or
ten minutes for your eyes to become "dark
adapted" before observing. Use a red-
filtered flashlight to protect your night vision
when reading star maps, or inspecting the
telescope. Do not use a regular flash-light
or turn on other lights when observing with
a group of other astronomers. You can make
your own red filtered flashlight by taping red
cellophane over a flashlight lens.
Viewing through windows: Avoid setting up
the telescope inside a room and observing
through an opened or closed window pane.
Images may appear blurred or distorted due
to temperature differences between inside
and outside air. Also, it is a good idea to
allow your telescope to reach the ambient
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.
(surrounding) outside temperature before
starting an observing session.
When to observe: Planets and other
objects viewed low on the horizon often lack
sharpness—the same object, when observed
higher in the sky, will appear sharper and
image
have greater contrast. Try reducing power
(change your eyepiece) if your image is fuzzy
or shimmers. Keep in mind that a bright, clear,
but smaller image is more interesting than a
larger, dimmer, fuzzy one. Using too high a
power eyepiece is one of the most common
mistakes made by new astronomers.
Dress Warm: Even on summer nights, the
air can feel cool or cold as the night wears
on. It is important to dress warm or to have a
sweater, jacket, gloves, etc., nearby.
Know your observing site: If possible, know
the location where you will be observing. Pay
attention to holes in the ground and other
obstacles. Is it a location where wild animals,
such as skunks, snakes, etc., may appear?
Are there viewing obstructions such as tall
trees, street lights, headlights and so forth?
The best locations are dark locations, the
darker the better. Deep space objects
are easiest to see under dark skies.
But it is still possible to observe even
in a city.
Surf the Web and visit your local library:
The internet contains a huge amount of
astronomical information, both for children
and adults. Check out astronomy books from
your library. Look for star charts—these are
available on a monthly basis in Astronomy
and Sky and Telescope magazines.
HAVE A GOOD TIME, ASTRONOMY IS FUN!
