Introduction

Congratulations on your purchase of a new precision-crafted telescope. With proper

care and handling of your telescope, you will enjoy the pleasure of looking at nature’s

wondrous sights through the eye of this instrument for many years.

This telescope has been designed to provide views of the moon’s craters, Jupiter’s

major moons, and Saturn’s rings, in addition to dozens of galaxies, star clusters, and

nebulae.

As a terrestrial (land) telescope, your telescope delivers great views of mountains,

valleys, and many other features of the world around us. You can also use it to study

animals and landscapes at a distance. To obtain the best performance from your

telescope, please read this manual carefully and completely.

ASSEMBLY

1) Carefully remove all parts from the cardboard cartons and lay them on a table or

floor in order to take an inventory of all the pieces. Keep your box for storage or in

case you ever need to ship your telescope.

2) Extend the legs, and lock each one at the desired height with the supplied tripod

adjustment knob (See Fig. 1).

(Fig. 1)

3) Connect all three tripod legs to the yoke with the supplied tripod leg attachment

bolts, washers and wing nuts (See Fig. 2).

(Fig. 2)

Azimuth Locking Knob

4) Fasten the tripod support bracket to each leg using the included bolts and nuts that

come attached to the end of each arm of the tripod support bracket. Remove each

bolt and nut. (See Fig. 3). Then position one arm of the tripod support bracket so that

the holes at the end of the arm line up with the hole through the attachment point on

the tripod leg (See Fig. 4). Insert the bolt to attach the tripod support bracket to the

tripod leg and tighten the nut. Repeat this procedure with the other two legs.

(Fig. 3) (Fig. 4)

5) Fasten the accessory tray to the tripod support bracket by placing the tray’s bolt

into the threaded hole and turning the tray clockwise until tight (See Fig. 5).

(Fig. 5)

6) After all nuts and bolts have been firmly tightened the telescope optical tube

assembly can be attached to the yoke. Mount the optical tube assembly in the yoke as

shown in Fig. 6 and tighten the two altitude control locking knobs.

(Fig. 6)

7) Remove the finder scope (with attached bracket) from the box. Remove the two

knurled thumbscrews from the telescope main tube (See Fig. 7). Position the finder

scope bracket onto the telescope tube so that the holes in the base of the bracket

line up with the exposed holes in the telescope tube. Replace the two knurled

thumbscrews and tighten securely (See Fig. 8).

(Fig. 7) (Fig. 8)

8) Insert the diagonal mirror into the focusing tube (See Fig. 9). Secure by tightening

the small chrome set screw located on the focusing tube (See Fig. 10).

(Fig. 9) (Fig. 10)

9) Insert the 25 mm eyepiece into the diagonal mirror (See Fig. 11). Tighten the

small chrome set screw to hold the eyepiece securely in place (See Fig. 12).

(Fig. 11) (Fig. 12)

10) A 3x Barlow lens is supplied to triple the basic magnifying power provided by an

eyepiece. In viewing situations where very high magnifying powers are desired, insert

the 3x Barlow lens between the eyepiece and the focusing tube (See Fig. 13).

(Fig. 13)

FINDER SCOPE ALIGNMENT

Since a telescope has a narrow field of view by design, it can be challenging to locate a

particular star or planet. For this reason the telescope is fitted with a low-power, wide-

field miniature telescope called a finder scope. Always use your finder scope to locate

the object you want to view FIRST. The finder scope should be aligned with the

main telescope tube before you begin using the telescope, in order that both

scopes are positioned to always provide exactly the same angle and view.

Note: Objects in the finder scope are upside down. This is normal and is common to all

astronomical telescopes.

Complete the following settings in daylight:

1) Insert the 25 mm eyepiece into the diagonal mirror. Look at an easily recognizable,

stationary object that is at least 300 feet away. Slightly loosen the two altitude control

locking knobs and the azimuth locking knob (See Fig. 2 - Page 4). Turn the telescope

on both its horizontal and vertical axis until the object is in the center of the field of

view. Then bring the image into focus.

2) Firmly re-tighten the adjusting knobs so that the telescope is locked in position.

3) Look through the finder scope. If the object is not visible or centered in the finder

scope, simply release one of the three small adjusting screws holding the finder scope

and reposition the finder scope until the object is centered within the “X” cross hairs.

4) All screws should be completely tightened as soon as the view through the finder

scope coincides with the view of the main telescope.

5) You may need to repeat this procedure to ensure a perfect alignment.

THE ALTAZIMUTH MOUNT

This telescope is fitted with an Altazimuth mount. “Alt” refers “Altitude”, the vertical

movement of the telescope, while “Azimuth” refers to the horizontal movement.

ABOUT MAGNIFICATION

The magnification power of a telescope indicates how much an image is enlarged or

how big and close it appears to the viewer. The focal length of the eyepiece, combined

with the focal length of the telescope, determines the magnification power. To calculate

the power of your telescope with any particular eyepiece, simply divide the focal length

of the telescope (700 mm) by the focal length of the eyepiece (indicated in “mm” on the

eyepiece collar).

Example: 700 mm focal length (tube) = 56X magnification power

12.5 mm focal length (eyepiece)

The 3X Barlow lens and interchangeable eyepieces provide the following magnification

values:

Eyepiece Power Power with 3X Barlow Lens

25 mm 28X 84X

12.5 mm 56X 168X

4 mm 175X 525X

The level of magnification required depends on the object being observed. Optimal

performance is obtained if the magnification is typically not more than appromiately 30X

for every 10 mm of objective lens diameter. Magnification of around 175X or less is

ideal for a telescope with a 60 mm diameter objective lens and is best for observing

most celestial objects. A lower magnification power and a wider field of view are

advisable for observing galaxies and nebulae. The highest magnification power should

be used for highly detailed observations of the moon, Jupiter and Saturn or any object

that is quite bright.

The highest magnification power of the Barlow lens / 4mm eyepiece combination should

only be used for large or bright objects such as the moon and the brightest planets.

USING YOUR TELESCOPE FOR ASTRONOMICAL VIEWING

1) Take your telescope outside. Viewing objects through closed or open windows is not

recommended. Your view can be distorted by reflections in the glass of a closed

window or by air currents of differing temperatures passing through an open window.

2) Let your telescope adjust to the outside temperature. Your telescope will perform

much better if the lenses and the air inside the tube are the same temperature as

outside. It may take up to 30 minutes to equalize the temperatures when the

difference in temperatures is extreme.

3) Find a location far from glaring light. If you live in an urban area, your viewing will

probably improve the farther you move away from the city lights. The sky glow of a

town or city can dramatically reduce the telescope’s performance and viewing

capabilities.

4) Remove the large, round plastic dust cover from the front of your telescope.

5) We recommend starting your viewing with the 25 mm eyepiece because it gives you

the widest angle and brightest, sharpest views. To adjust the angle of the telescope,

loosen the azimuth lock knob by turning it counterclockwise (See Fig. 2 - Page 4).

You can then aim the telescope in the desired direction. Then tighten the tripod

locking knob.

When possible, avoid sudden temperature changes, as the moisture in the air will

condense on the objective lens. Should this occur after bringing your telescope inside,

leave the lens cap off the objective lens, tilt the objective (front) lens face down, and

allow the telescope to reach room temperature.

NOTE: When using the diagonal mirror, objects will appear right side up in your

telescope, but reversed, like a reflection in a mirror. This is normal, and does not

indicate a defect.

USING YOUR TELESCOPE FOR TERRESTRIAL VIEWING

You may notice that when you observe a terrestrial subject on land or water it appears

right side up, but is reversed — like looking in a mirror.

Use the 1.5X image erector, included with your telescope, to reorient the object. This

accessory is inserted in the eyepiece holder of the telescope between the eyepiece and

the telescope, in the same manner as the 3X Barlow lens (See Fig. 16).

(Fig. 16)

The image erector provides 1.5X magnification, which means that the 25 mm eyepiece

will magnify objects from 28X to 42X when used in conjunction with the image erector.

NOTE: Do not use the diagonal mirror or the 3X Barlow lens with this accessory.
