WHERE DO I START?

Your Bushnell telescope can bring the wonders of the universe to your eye.

While this manual is intended to assist you in the set-up and basic use of this

instrument, it does not cover everything you might like to know about

astronomy. Although Northstar will give a respectable tour of the night sky,

it is recommended you get a very simple star chart and a flashlight with a red

bulb or red cellophane over the end. For objects other than stars and

constellations, a basic guide to astronomy is a must. Some recommended

sources appear on our website at www.bushnell.com. Also on our website

will be current events in the sky for suggested viewing. But, some of the

standbys that you can see are:

The Moon—a wonderful view of our lunar neighbor can be enjoyed with any

magnification. Try viewing at different phases of the moon. Lunar highlands, lunar

maria (lowlands called "seas" for their dark coloration), craters, ridges and

mountains will astound you.

Saturn—even at the lowest power you should be able to see Saturn’s rings and

moons. This is one of the most satisfying objects in the sky to see simply because

it looks like it does in pictures. Imagine seeing what you’ve seen in textbooks or

NASA images from your backyard!

Jupiter—the largest planet in our solar system is spectacular. Most noted features

are its dark stripes or bands both above and below its equator. These are the north

and south equatorial belts. Also interesting are Jupiter’s four major moons. Pay

close attention to their positions from night to night. They appear to be lined up on

either side of Jupiter.

Mars—The Great Red Planet appears as a reddish-orange disk. Look at different

times of the year and try to catch a glimpse of the white polar ice caps.

Venus—just like the moon, Venus changes phases from month to month. At times

Venus appears brilliantly in the night sky, just as if you were looking at a distant

crescent moon.

Nebulae—The Great Orion Nebula is a very well known night sky object. This and

many others are brought to you by this telescope.

Star Clusters—View millions of stars densely packed in a cluster that resembles

a ball.

Galaxies—One of the greatest and most interesting galaxies is our neighbor the

Andromeda Galaxy. Enjoy this and many others.

QUICK ASSEMBLY DIAGRAM

DETAILED ASSEMBLY

No tools are required for assembly of your telescope.

Remove all components from the carton and identify all components. It is a good idea to lay all the parts out in front of

you before assembly. Since your telescope is a precision optical system the parts require careful handling—particularly

the onboard computer, telescope, eyepieces, and various accessory lenses.

SET UP TRIPOD AND A C C E S S O RY T R AY

1. Stand Northstar Computerized Star Locator Assembly and attached tripod legs in

the upright position. Spread tripod legs to a comfortable distance.

2. Fold down the accessory tray braces and place the Quick Release Accessory

Tray on top of braces. (See Quick Assembly Diagram)

3. Turn accessory tray until it snaps into place.

4. Adjust tripod leg height to suit by opening tripod leg lever and extending tripod legs

to desired height. Clamp Tripod Leg lever closed when complete.

AT TACH TELESCOPE TUBE

1. Locate Main Telescope Tube.

2. Remove Telescope Tube Thumb Nuts from side of Telescope Tube.

(See Quick Assembly Diagram)

3. Position Main Telescope Tube Attachment Bolts through Telescope Tube Bracket at the top of the Northstar

Computerized Star Locator A s s e m b l y. Make sure the telescope is pointing in the correct direction. (Logo on

telescope tube should be right-side up.)

4. Reattach Telescope Tube Thumb Nuts to Main Telescope Tube Attachment Bolts once Main Telescope Tube and

Northstar Computerized Star Locator Assembly are assembled together.

AT TACH FINAL TELESCOPE A C C E S S O R I E S

1. Locate Red Dot Finderscope.

For Reflector Te l e s c o p e s : Remove Finderscope attachment nuts from Main Telescope Tube. Place Finderscope

Assembly over Finderscope Attachment Bolts and reattach Finderscope thumb nuts to Finderscope Mount Bolts.

N O T E : The large end of the finderscope should face the open end of telescope tube.

2. Attach Low Power Eyepiece.

For Reflector Telescope Models: Insert lowest power eyepiece in the focusing mechanism by backing out

eyepiece set screw and inserting eyepiece fully.

3. Tighten all set screws to secure accessories.

4. Remove Objective Dust Cover exposing entire diameter of open end of telescope.

SELECTING AN EYEPIECE

You should always start viewing with the lowest power eyepiece, which in this case is the 20 mm lens. Note: the base

power of each eyepiece is determined by the focal length of the telescope objective lens. A formula can be used to

determine the power of each eyepiece: telescope OBJECTIVE lens focal length divided by EYEPIECE focal length =

M A G N I F I C ATION (e.g. Using the 20 mm lens, a sample calculation could look like this: 750 mm / 20 = 38x or 38

p o w e r. Telescope models will vary in focal length.)

Included with this telescope is a Barlow lens. Barlow lenses are used to double or triple the power of your telescope.

Place your Barlow between the focusing tube and the eyepiece. Using the example above, your 3x Barlow lens would

give you a total power of 114x or 114 power. (38 x 3 = 114x or 114 power). The magnification calculation would look like

this: 750 mm /20mm = 38 power. 38 power x 3=114 power.

ALIGNING FINDERSCOPE

Look through Main Telescope Tube and establish a well-defined target. (see Focusing Telescope section)

Remove plastic insulator from between Red Dot Finderscope battery and battery clip.

Turn Red Dot Finderscope on.

Looking through Red Dot Finderscope, turn adjustment wheels until the red dot is precisely centered on the same object

already centered in Main Telescope Tu b e ’ s field of view.

N o w, objects located first with the Red Dot Finderscope will be centered in the field of view of the main telescope.

FOCUSING TELESCOPE

1. After selecting the desired eyepiece, aim main telescope tube at a land-based target at least 200 yards away

(e.g. a telephone pole or building).

2. Fully extend Focusing Tube by turning Rack and Pinion Focusing Mechanism.

3. While looking through selected eyepiece (in this case the 20 mm), slowly retract Focusing Tube by turning Rack

and Pinion Focusing Mechanism until object comes into focus.

DETAILED ASSEMBLY (CONTINUED)

ATTACH REMOTE COMPUTER CONTROLLER AND BATTERY

1. Locate Remote Computer Controller and coil cord.

2. Locate Battery Door on Northstar Computerized Star Locator Base.

3. Remove Battery Door and insert one 9V battery.

4. Replace Battery Door.

5. Attach Remote Computer Controller with coil cord to Northstar Computerized Star Locator Base.

ENJOYING YOUR NEW TELESCOPE

1. First determine your targeted object. Any bright object in the night sky is a good starting point.

One of the favorite starting points in astronomy is the moon. This is an object sure to please

any budding astronomer or experienced veteran. When you have developed proficiency at

this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good

second steps to take.

2. The first thing you need to do after assembling the telescope as planned is center the desired

object in the finderscope’s cross hairs. Provided you did a reasonable job aligning the

finderscope, a quick look through the main telescope tube at low power should reveal the

same image. With the lowest power eyepiece (the one with the largest number printed on it)

you should be able to focus the same image that you saw through the finderscope. Avoid the

temptation to move directly to the highest power. The low power eyepiece will give you a

wider field of view, and brighter image—thus making it very easy to find your target object. At

this point with a focused image in both scopes, you’ve passed the first obstacle. If you don’t

see an image after attempting to focus it in, you might consider aligning your finderscope

again. Once you pass this step, you’ll will enjoy the time spent ensuring a good alignment.

Every object you center in the finderscope will be easily found in the main telescope tube,

which is important for continuing your exploration of the night sky.

3. The low power eyepieces are perfect for viewing the full moon, planets, star clusters, nebulae,

and even constellations. These should build your foundation. However, for more detail, try

bumping up in magnification to higher power eyepieces on some of these objects. During

calm and crisp nights, the light/dark separation line on the moon (called the "Terminator") is

marvelous at high power. You can see mountains, ridges and craters jump out at you due to

the highlights. Similarly, you can move up to higher magnifications on the planets and nebulae.

Star clusters and individual stars are best viewed through the low power no matter what.

4. The recurring astronomical theater we call the night sky is an ever-changing billboard. In other

words, the same movie does not play all the time. Rather, the positions of the stars change

not only hourly as they seem to rise and set, but also throughout the year. As the earth orbits

the sun our perspective on the stars changes on a yearly cycle about that orbit. The reason

the sky seems to move daily just as the sun and the moon "move" across our sky is that the

earth is rotating about its axis. As a result you may notice that after a few minutes or a few

seconds depending on what power you are viewing at, the objects in your telescope will move.

At higher magnifications especially, you will notice that the moon or Jupiter will "race" right out

of the field of view. To compensate, just move your telescope to "track" it in the necessary path.

HELPFUL HINTS

1 . Your telescope is a very sensitive instrument. For best results and fewer vibrations

set your telescope up on a level location on the ground rather than your concrete

driveway or your wooden deck. This will provide a more stable foundation for

viewing, especially if you’ve drawn a crowd with your new telescope.

2. If possible view from a location that has relatively few lights. This will allow you to

see much fainter objects. You’d be surprised how much more you’ll see from your

local lake or park when compared to a backyard in the city.

3 . Using your telescope out a window is NEVER recommended.

4. View objects that are high in the sky if possible. Waiting until the object rises

well above the horizon will provide a brighter and crisper image. Objects on

the horizon are viewed through several layers of earth’s atmosphere. Ever

wonder why the moon appears orange as it sets on the horizon? It’s because

you are looking through a considerable more amount of atmosphere than you

would directly overhead. (Note: If objects high in the sky are distorted or

wavy, you are probably viewing on a very humid night.) During nights of

unstable atmosphere, viewing through a telescope can be frustrating if not

impossible. Astronomers refer to crisp, clear nights as nights of "good seeing."

After four simple criteria that any consumer should know, the telescope now knows where over 20,000 astronomical

objects are in the night sky to a relative precision. With just two more steps, you will zero in on pinpoint accuracy.

Now the telescope will lead you through a simple two star alignment process. YOU DO NOTNEED TO KNOW WHERE

A N Y S TARS ARE. You just simply follow the directions.

Ascrolling message indicates to CENTER STAR 1 THEN PRESS ENTER

Then the display will read:

Push the “GO” button and the telescope will automatically move to the general vicinity of the first guide star--in this

case MIZAR

The guide stars will be the brightest stars found in that area of the sky. Northstar will automatically “zero out” the guide

star and the display will read:

Note as you move from greater than 10 degrees away from an object to under ten degrees, the display moves into t e n t h s

of degrees with the arrows acting as decimal points (Example below the object).

After getting the star zeroed in, you need to do as the screen told you—CENTER STAR 1. In other words, the star might

appear in the lower left corner of your telescope’s eyepiece.

By looking through the eyepiece, center the star in the field of view by using the Motorized Movement Buttons or move

the telescope by hand and press ENTER.

14.

ALIGNING NORTHSTAR FOR THE FIRST TIME (Continued)

The distance the object is from the center is related to how far outside of a city you might be located or how

accurately you aligned with north.

Repeat this process for STAR 2 and press ENTER.

After this step is completed, you will see a display that reads:

(Note: The more stars that appear on the second line of the display the better, up to 5)

After the two star alignment is complete, your Northstar now knows with pinpoint accuracy where

all 20,000+ objects are!!

After EARTH ALIGN, the display will then read:

Select EXPLORE by pressing ENTER. SCROLL UP and DOWN to see what flashing menu choices you

have. Choose PLANET. These are the most interesting. Even if you are a first time telescope user,

PLANET objects can be very exciting.

Press ENTER when the display reads:

This will take you into a list of named PLANET objects. By using the SCROLL U Por SCROLLDOWN buttons,

you can explore several items in the object list.

Press ENTER to choose the PLANET you wish to view. The display will then be:

each object. But what if you are a first time user wanting to find out more about the object? Wouldn’t it be nice

to know what the object is before moving the telescope?

PRESS ENTER when:

any other PLANETitem is displayed. You will see a scrolling message telling you the coordinates for the object,

how bright it is, how big it is, what its proper name is, what constellation it is in, and a brief description of what

the object is. For JUPITER it reads:
