How To Use Your New Telescope

Selecting an Eyepiece:

1. Always begin viewing with the lowest

power eyepiece. (Note: a 20 mm focal

length eyepiece is lower power than a 10

mm one.) A formula can be used to

determine the power of each eyepiece:

Telescope focal length divided by eyepiece

focal length equals magnification. Ex.

400mm ÷ 20mm = 20X (magnification)

2. Included with this telescope is a 45°

Erecting Diagonal Prism. The Erecting

Diagonal Prism is used to erect the image

you will see. Astronomical telescopes are

designed in such a way that the image you

see may be UPSIDE DOWN and

REVERSED. This is acceptable for viewing

celestial bodies.

Focusing Telescope:

1. After selecting the desired eyepiece aim

the main telescope tube at a land-based

target at least 200 yards away (e.g. A

telephone pole or building). Fully extend

focusing tube by turning the focus knob.

2. While looking through selected eyepiece,

slowly retract focusing tube by turning

focusing knob until object comes into

focus.

Aligning Finderscope:

1. Look through Main Telescope Tube and

establish a well-defined target (see

focusing telescope section). Tighten all

lock knobs (Declination, Latitude, Right

Ascension, Horizontal Axis) so that

telescope’s aim is not disturbed.

2. Looking through the finderscope,

alternate tightening each finderscope

Adjustment Screw until the crosshairs of

the finderscope are precisely centered on

the same object already centered in Main

Telescope Tube’s field of view.

3. Now, objects located with the

finderscope first will be centered in field of

view of the main telescope.

WARNING!

NEVER LOOK DIRECTLY AT THE SUN WITH YOUR TELESCOPE.

PERMANENT DAMAGE TO YOUR EYES CAN OCCUR.
