Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Occur Thank you for purchasing the Bushnell Voyager Dobsonian Telescope! Your new telescope has been designed and crafted with the highest standards so that you may have years of enjoyment and use out of this wonderful window to the heavens. This product comes complete with everything you'll need to explore your universe including a professional primary mirror, precision rack and pinion focusing mechanism, superior all-metal main telescope tube, and professional quality wide-field 5x24mm finderscope. Whether you are just starting out in astronomy or you are an avid astronomer we wish you all the best with your telescope. Please utilize this manual to its fullest potential by reading it completely before you attempt to assemble and use your new telescope. Once assembled, we've included a basic guide on how to get started in astronomy at the end of this manual. While this is not a complete guide, it will give you some initial pointers. As you advance in ability, we would highly recommend a supplemental star atlas, beginning astronomy guide, moon map, or any other guide as you travel on your journey through the universe. READ THROUGH ASSEMBLY INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE TELESCOPE ASSEMBLY INSTRUCTIONS Your Bushnell Voyager Dobsonian Telescope comes preassembled from the factory. By simply attaching the accessory finderscope and eyepiece, you will be ready to explore. ATTACH FINDERSCOPE 1. Remove Reflector Telescope Assembly (2) and Finderscope (7) from carton. 2. Remove nuts located near the Rack & Pinion Focusing Mechanism (1) on Reflector Telescope Body (2). 3. Attach Finderscope (7) to Reflector Telescope Body (2) by inserting the bolts extending from the Reflector Telescope Body (2) into the holes in the base of the Finderscope (7). 4. Refasten nuts so that Finderscope (7) is secure. THE FINAL STEPS 1. Remove 1.25" Format Eyepiece (8) from carton. 2. Insert into Rack & Pinion Focusing Mechanism (1). 3. Remove Protective Dust Cover from end of telescope nearest the Rack & Pinion Focusing Mechanism (1). 4. Let the adventure begin. Your Bushnell Telescope is now ready to be used. To obtain the fullest enjoyment from your telescope, please refer to the following additional information. Astronomical Telescopes are designed in such a way that the image you will see appear will be UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. TELESCOPE USE SELECTING AN EYEPIECE: 1. 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 element, which for this model is 900 mm. A formula can be used to determine the power of each eyepiece: telescope OBJECTIVE mirror focal length EYEPIECE focal length = MAGNIFICATION (e.g. Using the 20 mm lens, the calculation would look like this: 900 mm . 20mm = 45x or 45 power.) 2. 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 81x or 81 power. (27 x 3 = 81x or 81 power) 3. Other accessories available include a 9mm eyepiece (model #78-0101) and a standard camera adapter (model #78-0104) for photographing the night sky. FOCUSING TELESCOPE: 1. After inserting the eyepiece, aim the 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 & Pinion Focusing Mechanism (1) 2. While looking through selected eyepiece (in this case the 20 mm), slowly retract focusing tube by turning Rack & Pinion Focusing Mechanism (1) until object comes into focus. ALIGNING FINDERSCOPE: 1. Look through low-power 1.25" format eyepiece (8) and establish a well-defined target (see focusing telescope section). 2. Looking through Finderscope (7), alternate tightening each Finderscope Adjustment Screw surrounding the Finderscope (7) in the Finderscope Mount until crosshairs of Finderscope (7) are precisely centered on the same object already centered in Main Telescope Tube's field of view as seen through the 1.25" Format Eyepiece (8). 3. Now, objects located first with the Finderscope (7) will be centered in the field of view of the main telescope as seen through the 1.25" Format Eyepiece (8). 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 veter...
