Congratulations on the purchase of your Bushnell Northstar Goto Telescope with Real Voice Output! This is
the first telescope ever created that actually speaks to you to educate you about the night sky. Consider this
feature as your personal astronomy assistant.

After reading through this manual and preparing for your observing session as outlined in these pages you
can start enjoying the Real Voice Output feature by doing the following:

To activate your telescope, simply turn it on! The Real Voice Output feature is built in to the remote control
handset.

Along the way the telescope will speak various helpful comments during the alignment process. Once aligned,
the Real Voice Output feature will really shine anytime the enter key is depressed when an object name or
number is displayed at the bottom right of the LCD viewscreen. That object description will be spoken to
you as you follow along with the scrolling text description.

If at anytime you wish to disable the speaking feature, you can cancel the speech by pressing the “Back”
button on the remote control keypad.

It is our sincere hope that you will enjoy this telescope for years to come!

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.

T

ry 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.
T

his 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
dar

k 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

pears brilliantly in the night sky, just as if you were looking at a distant crescent moon.

ap

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

rs are brought to you by this telescope.

Star Clusters—

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

. Enjoy this and many others.

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.

3. Tighten all set screws to secure accessories.

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 = MAGNIFICATION (e.g. Using the 20 mm
lens, a sample calculation could look like this: 750 mm / 20 = 38x or 38 power. Telescope models will vary in focal length.)

(Reflectors Only)

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.

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

o take.

t

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.

M

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 d
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

ainter objects. You’d be surprised how much more you’ll see from your local lake or park

f
when compared to a backyard in the city.

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

riveway or your

4. View objects that are high in the sky if possible. W

several layers of earth’s atmosphere. Ever wonder why the moon appears orange as it sets on
the horizon? I
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.”
