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!
Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Occur

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. Some of the standbys that you can see are: The Moona 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. Saturneven at the lowest power you should be able to see Saturns 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 youve seen in textbooks or NASA images from your backyard! Jupiterthe 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 Jupiters four major moons. Pay close attention to their positions from night to night. They appear to be lined up on either side of Jupiter. MarsThe 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.
Venusjust 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. NebulaeThe Great Orion Nebula is a very well known night sky object. This and many others are brought to you by this telescope. Star ClustersView millions of stars densely packed in a cluster that resembles a ball. GalaxiesOne of the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. 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 handlingparticularly the onboard computer, telescope, eyepieces, and various accessory lenses. SET UP TRIPOD AND ACCESSORY TRAY 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. ATTACH 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 Assembly. 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. ATTACH FINAL TELESCOPE ACCESSORIES 1. Locate Red Dot Finderscope. For Reflector Telescopes: Remove Finderscope attachment nuts from Main Telescope Tube. Place Finderscope Assembly over Finderscope Attachment Bolts and reattach Finderscope thumb nuts to Finderscope Mount Bolts. NOTE: 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 = 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.) 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.

DETAILED ASSEMBLY (CONTINUED)

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. M
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.

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 Tubes field of view. Now, objects located first with the Red Dot Finderscope will be centered in the field of view of the main telescope.
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 finderscopes 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 imagethus making it very easy to find your target object. At this point with a focused image in both scopes, youve passed the first obstacle. If you dont see an image after attempting to focus it in, you might consider aligning your finderscope again. Once you pass this step, youll 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 youve 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. Youd be surprised how much more youll 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 earths atmosphere. Ever wonder why the moon appears orange as it sets on the horizon? Its 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."

Each flashing option will need to be changed to read the appropriate number. Once the appropriate number is displayed, accept the number by pressing ENTER. Then set the next flashing option until the time and time zone are set. STEP 3: SET THE DATE Again by using the SCROLL UP and SCROLL DOWN buttons and the ENTER button, the date can easily be set. Each flashing option will need to be changed to read the appropriate number or month. Once the appropriate number is displayed, accept the number by pressing ENTER. Then set the next flashing option until the day, month and year are set. STEP 4: SET THE LOCATION The next screen will display: ALIGN EARTH CITY ][ CITY will be flashing. By pressing the ENTER button, the display will change to: COUNTRY U.S.A.][ The country will be flashing. Again by using the SCROLL UP and SCROLL DOWN buttons and the ENTER button, the COUNTRY can be chosen. When the appropriate Country is found and the ENTER button is pushed, choose the city that you are closest to by pressing ENTER when it is displayed. NOTE: CHOOSE THE CITY CLOSEST TO YOUR VIEWING LOCATION. THIS IS NOT A CRITICAL STEP AND THE ALIGNMENT WILL BE REFINED AUTOMATICALLY AS WE PROGRESS. 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 NOT NEED TO KNOW WHERE ANY STARS ARE. You just simply follow the directions. A scrolling message indicates to CENTER STAR 1 THEN PRESS ENTER Then the display will read: CENTER STAR 1 {120 ]52 MIZAR 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: CENTER STAR 00 MIZAR Note as you move from greater than 10 degrees away from an object to under ten degrees, the display moves into tenths of degrees with the arrows acting as decimal points (Example 8]5=8.5 degrees below the object). After getting the star zeroed in, you need to do as the screen told youCENTER STAR 1. In other words, the star might appear in the lower left corner of your telescopes 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.

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: ALIGN COMPLETE RATING ***** (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!!

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 Moona 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. Saturneven at the lowest power you should be able to see Saturns 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 youve seen in textbooks or NASA images from your backyard! Jupiterthe 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 Jupiters four major moons. Pay close attention to their positions from night to night. They appear to be lined up on either side of Jupiter. MarsThe 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. Venusjust 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. NebulaeThe Great Orion Nebula is a very well known night sky object. This and many others are brought to you by this telescope. Star ClustersView millions of stars densely packed in a cluster that resembles a ball. GalaxiesOne of the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. 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 handlingparticularly the onboard computer, telescope, eyepieces, and various accessory lenses. SET UP TRIPOD AND ACCESSORY TRAY 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. ATTACH TELESCOPE TUBE 1. Locate Main Telescope Tube. 2. Remove Telescope Tube Thumb Nuts from side of Telescope Tube (78-8831 and 78-8846 only). For 78-8890, back out silver lug screw on Telescope Mount top. 3. Position Main Telescope Tube Attachment Bolts through Telescope Tube Bracket at the top of the Northstar Computerized Star Locator Assembly (78-8831 and 78-8846 only). For 78-8890, slide black telescope tube bracket into telescope mount receiver. Make sure telescope is pointing in the correction direction. (Logo on telescope tube should be rightside 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 (78-8831 and 78-8846 only). For 78-8890, tighten silver lug screw on Telescope Mount top into desired depression on the black telescope tube bracket. ATTACH FINAL TELESCOPE ACCESSORIES 1. Locate Red Dot Finderscope. For Reflector Telescopes: Remove Finderscope attachment nuts from Main Telescope Tube. Place Finderscope Assembly over Finderscope Attachment Bolts and reattach Finderscope thumb nuts to Finderscope Mount Bolts. NOTE: 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. 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.) 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.

2. The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscopes 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 imagethus making it very easy to find your target object. At this point with a focused image in both scopes, youve passed the first obstacle. If you dont see an image after attempting to focus it in, you might consider aligning your finderscope again. Once you pass this step, youll 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.

MODE OVERVIEW OF PRODUCT

Explore: The Explore Mode of Northstar provides the ability to explore various astronomical objects categorized by object type. These objects would fall under one or more of the following types of objects: Deep Sky, Planets, Constellations, and Stars. Each of these subheadings would also have subcategories of objects beneath their menu structure. (See Menu Tree for full list of menu functions and options.) Sky Tour: The Sky Tour Mode of Northstar provides the ability to take a quick tour of the best and brightest objects for any given month of the year. If the date has been input into the system, the Sky Tour Mode will automatically default to that month. Objects can be chosen by using the scroll up or down arrows and pressing ENTER. To find out more information about any given object press the ENTER button while that object is displayed to see the scrolling text message. Telescope: The Telescope Mode of Northstar provides real-time data on where the telescope is pointing. Astronomical Coordinates for Right Ascension (RA) and Declination (DEC) as well as Altitude (ALT) and Azimuth (AZ) are displayed simultaneously. In addition, in the lower right-hand corner will be the abbreviation for the current constellation that the telescope is pointed at. Identify: The Identify Mode of Northstar provides the ability to identify any object within your telescope field of view. Subcategories for different classes of identifiable objects are included as well as an Identify Any option. Align Earth: The Align Earth Mode of Northstar provides the ability to easily align your telescope utilizing common information non-astronomers would readily know. By entering simple information such as time, date, city, etc. a first time telescope user can explore the immense Northstar database of astronomical objects within minutes. Align Star: The Align Star Mode of Northstar provides the ability to align your telescope utilizing some astronomical knowledge. By knowing where two stars are located in the sky, a novice user can circumvent the city, date, and time input and quickly start utilizing the Northstar database to locate amazing astronomical objects. Align Object: The Align Object Mode of Northstar provides the ability to refine your telescope alignment during the middle of your observing session. This might come in very handy if the family dog has just bumped the telescope out of alignment. By using this mode you can center the telescope on any known object and select align object to quickly recalibrate the Northstar alignment allowing continued enjoyment for the duration of the evening.

ALIGNING NORTHSTAR FOR THE FIRST TIME
(NOTE: Make certain that the telescope is set up on a level surface.) STEP 1: POINT NORTH Point the telescope in the direction of North. NOTE: THE USER SHOULD JUST ATTEMPT TO GET THE TELESCOPE POINTED RELATIVELY CLOSE TO NORTH. THE ALIGNMENT WILL BE REFINED AS WE PROGRESS. HOWEVER, IF YOU CAN FIND THE BIG DIPPER AND USE THE "POINTER STARS", FOLLOW THE ARROW ON THE DIAGRAM TO THE NORTH STAR. THE NORTH STAR LIES DIRECTLY ABOVE DUE NORTH!
Before turning the telescope on, remove the remote control handset. When you turn the telescope on, a spoken and scrolling message will occur: BUSHNELL NORTHSTAR Vx.x Following this message, the telescope will execute a diagnostic check and level the telescope tube in relation to the telescope mount. Then the default menu will appear: SELECT MODE ALIGN EARTH ][ This mode assumes that even if the telescope user is a first time user and does not know anything about astronomy that they can be successful aligning the telescope in a few simple steps. The ALIGN EARTH option is flashing. Press ENTER to choose ALIGN EARTH option. NOTE: ANY FLASHING ITEM ON THE DISPLAY IS A MENU CHOICE. OTHER CHOICES ARE AVAILABLE BY USING 13.

ALIGNING NORTHSTAR FOR THE FIRST TIME (Continued)
STEP 2: SET THE TIME By using the SCROLL UP and SCROLL DOWN buttons and the ENTER button, the time can easily be set as well as the time zone. Each flashing option will need to be changed to read the appropriate number. Once the appropriate number is displayed, accept the number by pressing ENTER. Then set the next flashing option until the time and time zone are set. STEP 3: SET THE DATE Again by using the SCROLL UP and SCROLL DOWN buttons and the ENTER button, the date can easily be set. Each flashing option will need to be changed to read the appropriate number or month. Once the appropriate number is displayed, accept the number by pressing ENTER. Then set the next flashing option until the day, month and year are set. STEP 4: SET THE LOCATION The next screen will display: ALIGN EARTH CITY ][ CITY will be flashing. By pressing the ENTER button, the display will change to: COUNTRY U.S.A.][ The country will be flashing. Again by using the SCROLL UP and SCROLL DOWN buttons and the ENTER button, the COUNTRY can be chosen. When the appropriate Country is found and the ENTER button is pushed, choose the city that you are closest to by pressing ENTER when it is displayed. NOTE: CHOOSE THE CITY CLOSEST TO YOUR VIEWING LOCATION. THIS IS NOT A CRITICAL STEP AND THE ALIGNMENT WILL BE REFINED AUTOMATICALLY AS WE PROGRESS. 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 NOT NEED TO KNOW WHERE ANY STARS ARE. You just simply follow the directions. A scrolling message indicates to CENTER STAR 1 THEN PRESS ENTER Then the display will read: CENTER STAR 1 {120 ]52 MIZAR 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: CENTER STAR 00 MIZAR Note as you move from greater than 10 degrees away from an object to under ten degrees, the display moves into tenths of degrees with the arrows acting as decimal points (Example 8]5=8.5 degrees below the object). After getting the star zeroed in, you need to do as the screen told youCENTER STAR 1. In other words, the star might appear in the lower left corner of your telescopes eyepiece.

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: ALIGN COMPLETE RATING ***** (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 M

all 20,000+ objects are!! After EARTH ALIGN, the display will then read: SELECT MODE EXPLORE ][ 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: EXPLORE PLANET This will take you into a list of named PLANET objects. By using the SCROLL UP or SCROLL DOWN buttons, you can explore several items in the object list. PLANET JUPITER ][ Press ENTER to choose the PLANET you wish to view. The display will then be: PLANET {120 ]52 JUPITER
NOTE: IF AN OBJECT IS BELOW THE HORIZON, THE DISPLAY WILL PERIODICALLY DISPLAY THE WORD "HORIZON". SCROLL UP or SCROLL DOWN to see other PLANETS in the list. Notice the display shows you directions to each object. But what if you are a first time user wanting to find out more about the object? Wouldnt it be nice to know what the object is before moving the telescope? PRESS ENTER when: PLANET {120 ]52 JUPITER
any other PLANET item 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: JUPITER fifth planet from sun.
