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! 2. 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. 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. 3.

PARTS LIST · Adjustable Aluminum Tripod Assembly · Quick Release Accessory Tray · Northstar Telescope with finger attachment nuts · Red Dot Finderscope · 2 Eyepieces · Barlow Lens (Reflectors Only) · 90° Erecting Prism (Maksutov Only) (Pre-assembled to Northstar Computerized Star Locator Base) 5. 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 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. 3. 4. Fold down the accessory tray braces and place the Quick Release Accessory Tray on top of braces. (See Quick Assembly Diagram) Turn accessory tray until it snaps into place. 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. 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 right-side up.) 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. 3. 4. 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. Tighten all set screws to secure accessories. 3. 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. 6. DETAILED ASSEMBLY (CONTINUED) M FOCUSING TELESCOPE 1. 2. 3. 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). Fully extend Focusing Tube by turning Rack and Pinion Focusing Mechanism. 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. 2. 3. 4. 5. Locate Remote Computer Controller and coil cord. Locate Battery Door on Northstar Computerized Star Locator Base. Remove Battery Door and insert one 9V battery. Replace Battery Door. Attach Remote Computer Controller with coil cord to Northstar Computerized Star Locator Base. M 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 Tube's field of view. Now, objects located first with the Red Dot Finderscope will be centered in the field of view of the main telescope. NEVER LOOK DIRECTLY AT THE SUN WITH YOUR TELESCOPE PERMANENT DAMAGE TO YOUR EYES MAY OCCUR 7. M 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. 8. 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 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. 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. Using your telescope out a window is NEVER recommended. 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." 2. 3. 4. 9.

Bien que ce manuel soit conçu pour vous aider à installer et à utiliser cet instrument simplement, il ne couvre pas tout ce que vous aimeriez savoir sur l'astronomie. Même si Northstar donne une bonne vue d'ensemble du ciel nocturne, il est recommandé de se procurer une carte très simple des étoiles et une lampe de poche avec une ampoule rouge ou recouverte de cellophane rouge à l'extrémité. Pour les objets autres que les étoiles et constellations, il est nécessaire d'avoir un guide de base d'astronomie. Vous trouverez les sources recommandées sur notre site Internet à: www.bushnell.com. Vous y trouverez également les événements du ciel actuels et les suggestions d'observation. Mais, parmi les éléments principaux que vous pouvez voir, il y a : La Lune--une vue magnifique de notre voisine s'obtient à n'importe quel grossissement. Essayez d'observer ses différentes phases. Les montagnes lunaires, les mers lunaires (étendues basses ainsi appelées à cause de leur couleur sombre), les cratères, les crêtes vous étonneront. Saturne--même au grossissement le plus faible, vous devriez pouvoir voir ses anneaux et ses lunes. C'est l'un des objets les plus intéressants du ciel à observer car il ressemble vraiment à sa représentation sur les images. Imaginez que vous pouvez voir depuis votre jardin ce que vous avez vu dans des livres ou sur des images de la NASA ! Jupiter--la planète la plus grosse de notre système solaire est spectaculaire. Ses traits caractéristiques sont ses rayures ou bandes sombres au-dessus et au-dessous de son équateur. Ce sont les ceintures équatoriales du nord et du sud. Les quatre lunes principales de Jupiter sont aussi intéressantes. Remarquez leurs différentes positions une nuit après l'autre. Elles semblent alignées de chaque côté de Jupiter. Mars--La grande planète rouge apparaît comme un disque rouge orangé. Observez-la à différents moments de l'année pour essayer d'apercevoir les chapeaux de glace polaire blancs. Vénus--tout comme la Lune, Vénus change de phases d'un mois à l'autre. Par moments, elle est très brillante dans le ciel nocturne, comme si l'on regardait une lune en croissant distante. Nébuleuses--La grande nébuleuse d'Orion est un objet très connu du ciel nocturne. Vous pourrez voir celle-ci et bien d'autres grâce à ce télescope. Amas d'étoiles--Regardez des millions d'étoiles groupées de manière dense en un amas qui ressemble à une boule. Galaxies--L'une des galaxies les plus grandes et les plus intéressantes est notre voisine la galaxie d'Andromède. Vous l'aimerez ainsi que bien d'autres. 37.

ASSEMBLAGE DÉTAILLÉ Aucun outil n'est nécessaire pour l'assemblage du télescope. Sortez toutes les pièces du carton et identifiez-les. Avant de faire l'assemblage, il est conseillé de poser toutes les pièces devant soi. Le télescope étant un système optique de précision, veuillez manipuler les pièces avec précaution : en particulier l'ordinateur intégré, le télescope, les oculaires et les diverses lentilles accessoires. MISE EN PLACE DU TRÉPIED ET DU PLATEAU D'ACCESSOIRE 1. 2. 3. 4. Mettez debout l'ensemble du dispositif de repérage d'étoiles informatisé Northstar et les pieds de trépied attachés. Écartez les pieds de trépied à une distance confortable. Abaissez les renforts du plateau d'accessoire et placez le plateau d'accessoire à ouverture rapide au-dessus des renforts. (Reportez-vous au schéma d'assemblage rapide). Tournez le plateau d'accessoire jusqu'à ce qu'il s'enclenche avec un déclic. Réglez la hauteur du trépied en actionnant le levier des pieds et en écartant les pieds pour obtenir la hauteur souhaitée. Resserrez le levier en position fermée une fois le réglage terminé. FIXATION DU TUBE DU TÉLESCOPE 1. 2. 3. Trouvez le tube principal du télescope. Retirez les écrous à oreilles du tube du télescope situés sur le côté du tube (78-8831 et 78-8846 uniquement). Pour le 78-8890, dévissez légèrement la vis taquet argent sur le dessus de la monture du télescope. Faites passer les boulons de fixation du tube principal du télescope à travers le support du tube du télescope, en haut de l'ensemble du dispositif de repérage d'étoiles informatisé Northstar (78-8831 et 78-8846 uniquement). Pour le 78-8890, glissez le support de tube noir du télescope dans le berceau de la monture du télescope. Vérifiez que le télescope est dirigé dans la bonne direction. (Le logo situé sur le tube du télescope doit être à l'endroit). Une fois que le tube principal du télescope et l'ensemble du dispositif de repérage d'étoiles informatisé Northstar sont assemblés l'un à l'autre, fixez les écrous à oreilles aux boulons de fixation du tube principal du télescope (78-8831 et 78-8846 uniquement). Pour le 78-8890, serrez la vis taquet argent sur le dessus de la monture du télescope, au creux souhaité sur le support de tube noir du télescope. 4. FIXATION DU RESTE DES ACCESSOIRES DU TÉLESCOPE 1. Trouvez le chercheur à point rouge. Pour les télescopes à réflecteur: Retirez les écrous de fixation du chercheur du tube principal du télescope. Placez le chercheur par-dessus les boulons de fixation et reposez les écrous à oreilles du chercheur sur les boulons de fixation. REMARQUE: La grande extrémité du chercheur doit être en face de l'extrémité ouverte du tube du télescope. 2. Fixez l'oculaire à faible grossissement. Pour les modèles de télescopes à réflecteur : Insérez l'oculaire à grossissement le plus faible dans le mécanisme de mise au point en dévissant la vis de serrage d'oculaire et en poussant l'oculaire à fond. 3. Vissez toutes les vis de serrage pour fixer les accessoires. CHOIX D'UN OCULAIRE Il est recommandé de toujours commencer l'observation avec l'oculaire au grossissement le plus faible, dans ce cas, la lentille de 20 mm. Remarque: le grossissement de base de chaque oculaire est déterminé par la longueur focale de l'objectif du télescope. Il existe une formule servant à déterminer le grossissement de chaque oculaire: Longueur focale de l'OBJECTIF du télescope divisée par la longueur focale de l'OCULAIRE = GROSSISSEMENT (ex. : en utilisant une lentille de 20 mm, le calcul serait: 750 mm / 20 = 38 x ou grossissement de 38 fois. La longueur focale varie suivant les modèles de télescopes). (Réflecteur) Un oculaire Barlow est inclus avec ce télescope. Les oculaires Barlow servent à doubler ou à tripler le grossissement du télescope. Placez l'oculaire Barlow entre le tube de mise au point et l'oculaire. Dans l'exemple ci-dessus, l'oculaire Barlow de 3 x donnerait un grossissement total de 114 x ou 114 fois. (38 x 3 = 114 x ou 114 fois). Le calcul du grossissement serait: 750 mm / 20 mm = 38 fois. 38 fois x 3 = 114 fois. 40. ASSEMBLAGE DÉTAILLÉ (SUITE) M MISE AU POINT DU TÉLESCOPE 1. Après avoir mis en place l'oculaire choisi, dirigez le tube principal du télescope sur une cible terrestre située à une distance d'au moins 200 mètres (poteau téléphonique ou bâtiment, par exemple). Tournez le mécanisme de mise au point à crémaillère et pignon pour allonger entièrement le tube de mise au point. Tout en regardant dans l'oculaire choisi (celui de 20 mm dans ce cas), rétractez lentement le tube de mise au point en tournant le mécanisme de mise au point à crémaillère et pignon jusqu'à ce que l'objet soit net. 2. 3. FIXATION DU CONTRÔLEUR D'ORDINATEUR À DISTANCE ET DE LA PILE 1. 2. 3. 4. Trouvez le contrôleur d'ordinateur à distance et le cordon spiralé. Trouvez le couvercle de compartiment de pile sur la base du dispositif de repérage d'étoiles informatisé Northstar. Enlevez le couvercle du compartiment de pile et placez-y une pile de 9 V. Remettez le couvercle en place sur le compartiment. 5. Fixez le contrôleur d'ordinateur à distance avec le cordon spiralé sur la base du dispositif de repérage d'étoiles informatisé Northstar. M ALIGNEMENT DU CHERCHEUR Regardez dans le tube principal du télescope et établissez une cible bien définie. (Reportez-vous à la section de mise au point du télescope). Retirez l'isolateur en plastique se trouvant entre la pile du chercheur à point rouge et le clip de pile. Activez le chercheur à point rouge. En regardant dans le chercheur à point rouge, tournez les molettes de réglage jusqu'à ce que le point rouge soit centré précisément sur l'objet déjà centré dans le champ du tube principal du télescope. Désormais, les objets repérés d'abord à l'aide du chercheur à point rouge seront centrés dans le champ du tube principal du télescope. NE REGARDEZ JAMAIS DIRECTEMENT LE SOLEIL À TRAVERS LE TÉLESCOPE. RISQUE DE LÉSIONS OCULAIRES PERMANENTES. 41. M PROFITEZ DE VOTRE NOUVEAU TÉLESCOPE. 1. Déterminez d'abord l'objet à observer. N'importe quel objet brillant du ciel nocturne est un bon point de départ. L'un des points de départ préférés en astronomie est la Lune. C'est un objet intéressant pour l'astronome débutant aussi bien que pour les astronomes expérimentés. Lorsque vous vous êtes exercés à ce niveau, d'autres objets deviennent de bonnes cibles. Saturne, Mars, Jupiter et Vénus sont intéressantes en seconde étape. 2. La première chose que vous devez faire après l'assemblage du télescope comme prévu est de centrer l'objet choisi dans la croisée de fils du chercheur. À condition que vous ayez suffisamment bien aligné le chercheur, un coup d'oeil rapide dans le tube principal du télescope à faible grossissement doit révéler la même image. Avec l'oculaire de plus faible grossissement (celui qui a le nombre le plus grand inscrit dessus), vous devriez pouvoir mettre au point la même image que celle que vous avez vue dans le chercheur. Évitez la tentation de passer directement au grossissement le plus fort. L'oculaire de faible grossissement donne une plus grande largeur de champ et une image plus brillante, ce qui facilite le repérage de l'objet cible. À ce moment, avec une image mise au point dans les deux lunettes, vous avez franchi le premier obstacle. Si vous ne voyez pas d'image après avoir essayé de la mettre au point, pensez à aligner de nouveau le chercheur. Une fois cette opération effectuée, vous pourrez apprécier le temps passé pour obtenir un alignement correct. Chaque objet que vous centrerez dans le chercheur apparaîtra facilement dans le tube principal du télescope, ce qui est important pour continuer l'exploration du ciel nocturne. 3. Les oculaires de faible grossissement sont parfaits pour observer la pleine lune, les planètes, les amas d'étoiles, les nébuleuses et même les constellations. Ces objets constituent votre base. Toutefois, pour voir plus de détails, essayez d'utiliser des oculaires à plus fort grossissement sur certains de ces objets. Durant les nuits calmes et vives, la ligne de séparation des parties éclairée et obscure de la Lune (appelée « Terminateur ») est merveilleuse à fort grossissement. Les montagnes, crêtes et cratères paraissent avec un fort relief à cause de la mise en lumière. De manière similaire, vous pouvez utiliser de plus forts grossissements sur les planètes et nébuleuses. Quant aux amas d'étoiles et aux étoiles individuelles, la meilleure observation s'effectue toujours à faible grossissement. 4. Le théâtre astronomique renouvelé que nous appelons le ciel nocturne est un écran géant toujours changeant. Autrement dit, ce n'est pas toujours le même film qui repasse. Bien au contraire, les positions des étoiles changent non seulement d'heure en heure alors qu'elles semblent se lever et se coucher, mais aussi tout au long de l'année. À mesure que la Terre tourne autour du Soleil, notre vue des étoiles change sur un cycle annuel, selon cette orbite. La raison pour laquelle le ciel semble se déplacer chaque jour, tout comme le Soleil et la Lune « se déplacent » dans le ciel, c'est que la Terre tourne autour de son axe. C'est ainsi que vous pouvez remarquer qu'au bout de quelques minutes ou quelques secondes, suivant le grossissement utilisé, les objets se déplacent dans le télescope. Aux forts grossissements surtout, vous remarquerez que la Lune ou Jupiter « courent » et sortent du champ rapidement. Pour compenser, déplacez simplement le télescope pour qu'il suive sa trajectoire. 42. M CONSEILS UTILES 1. Le télescope est un instrument très sensible. Pour obtenir les meilleurs résultats et le moins de vibrations, installez le télescope sur un endroit plat, sur le sol plutôt que sur une surface en béton ou une plate-forme en bois. Cela fournira une base plus stable pour l'observation, surtout si votre nouveau télescope a attiré une foule. 2. Si possible, observez à partir d'un endroit comportant relativement peu de lumière. Vous pourrez ainsi voir des objets d'une luminosité plus faible. Vous serez surpris(e) de constater que vous pouvez voir bien plus d'objets célestes à partir d'un lac ou d'un parc local qu'à partir d'un jardin situé en ville. 3. Il N'est JAMAIS recommandé d'observer avec le télescope à partir d'une fenêtre. 4. Autant que possible, observez les objets qui sont hauts dans le ciel. Attendez que l'objet monte bien au-dessus de l'horizon pour obtenir une image plus brillante et plus nette. Les objets situés à l'horizon sont aperçus à travers plusieurs couches de l'atmosphère terrestre. Vous êtesvous jamais demandé pourquoi la Lune paraît orange lorsqu'elle se couche à l'horizon? C'est parce que vous la regardez à travers une quantité d'atmosphère bien plus grande qu'il n'y en a directement au-dessus. (Remarque: Si les objets hauts dans le ciel paraissent déformés ou ondulés, la nuit est probablement très humide). Durant les nuits où l'atmosphère est instable, l'observation avec un télescope peut être difficile sinon impossible. Les astronomes parlent des nuits vives et claires comme des nuits de "bonne observation". 43. ORDINATEUR NORTHSTAR SCHÉMA D'INTERFACE 1. 2. 3. 4. 5. 6. 7. 8. 9.
