that the object to be viewed is again placed

at the edge of the field, ready to be further

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 image 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. Stay away from bright lights too.

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 (surrounding) outside

temperature before starting an observing

session.
When to observe: Planets and other objects

viewed low on the horizon often lack sharp-

ness—the same object, when observed

higher in the sky, will appear sharper and

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

JOIN AN ASTRONOMY CLUB, ATTEND A STAR

PARTY

One of the best ways to increase your knowledge of

astronomy is to join an astronomy club. Check your

local newspaper, school, library, or telescope dealer/

store to find out if there’s a club in your area.

Many groups also hold regularly scheduled Star Parties

at which you can check out and observe with many

different telescopes and other pieces of astronomical

equipment. Magazines such as Sky and Telescope

and Astronomy print schedules for many popular Star

Parties around the United States and Canada.

movement is caused by the rotation of the

Earth and makes an object move through

the telescope’s field of view. To keep

astronomical objects centered in the field,

simply move the telescope on one or both

of its axes—vertically and/or horizontally as

needed—try using the telescopes coarse and

fine 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 telescope so

Looking at or near the

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