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. READ THROUGH ASSEMBLY INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE. The only tool required in setting up your telescope is a slotted or Phillips blade screwdriver. Since your telescope is a precision optical system the parts require careful handling--particularly the telescope, eyepieces, and various accessory lenses. 2. Set-Up Tripod · Select one tripod leg. Loosen Tripod Leg Lock Screw (8) and extend the Tripod Leg Middle Section (12). For a moment, do not extend the leg fully...a shorter leg is less awkward to work with during set-up. Tighten the Tripod Leg lock Screw so that the Middle Section is securely in place. Repeat for the remaining two legs. 3. Attach Telescope and Finderscope · Locate the pre-assembled Telescope Main Tube (2) and Equatorial Mount. Note: Before assembling tripod legs to Equatorial Mount, make sure the Accessory Tray Braces (10) face inward. Carefully remove Telescope Main Tube from Cradles. Position the mount between Tripod Leg as shown (fig. 2). Secure Equatorial Mount to Tripod Leg using tripod bolts. Repeat on the remaining two Tripod Legs. Once you have attached all Tripod Legs to the mount, securely tighten all wing nuts and place Telescope Main Tube back into Cradles. · · Remove plastic insert on bottom side of finderscope to allow battery to make connection with battery contact for power. Turn power switch on. See finderscope page. Look through main telescope tube at low power and establish a well-defined stationary target. Looking through red dot finderscope, alternate tightening each adjustment wheel (at rear and left side of finderscope) until the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope tube. See finderscope page. Fig. 2 4. Attach Accessory Tray Locate the Accessory Tray (11). Using the accessory tray bolts, wingnuts and washers connect the Accessory Tray to the Accessory Tray Braces (10). Start with one tripod leg and attach wingnuts. Wingnuts should be positioned beneath the accessory tray. Do not tighten wingnuts until all Accessory Tray Braces are attached, as some adjustments may be required. 5. Attach Control Cables, Counterweight and Eyepieces Locate the Fine Adjustment Cables (14). Loosen the silver screws located at the end of the Fine Adjustment Cables and attach the Fine Adjustment Cables to the two silver posts found on the Equatorial Mount. The first post is located just above the Declination Lock Knob (3), the second post is located below the Right Ascension Lock Knob (4). 6. Locate the Counterweight (6) and Counterweight Shaft (5). Loosen the thumbscrew located on the Counterweight and slide the Counterweight onto the Counterweight Shaft, then and tighten thumbscrew to secure the Counterweight. Thread the Counterweight Shaft into the hole located directly below the Declination Lock Knob (3). Make sure that the shaft is securely locked into mount. 7. Insert Eyepiece (17) into focusing tube to begin viewing. Your Bushnell Voyager Telescope is now ready to be used. To obtain the fullest enjoyment from your telescope, please refer to the additional information below. HOW TO USE YOUR NEW TELESCOPE Astronomical telescopes are designed in such a way that the image you will see appear UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. Using the Penta Mirror Assembly: 1. A Basic Description: Bushnell is proud to present the Exclusive Penta Mirror Technology. This Penta Mirror Assembly provides the benefit of a convenient 90 degree viewing angle commonly associated with diagonal mirrors. However, the Penta Mirror provides something that diagonal mirrors cannot provide--right to left correct views of the any object viewed through the telescope. Unlike traditional diagonal mirrors that provide backward images of objects seen on land and in the night sky, the Penta Mirror allows correct images to be viewed. The groundbreaking benefit of this technology is that when viewing and locating objects through the telescope, when you want to move to the left, you move it to the left intuitively instead of fumbling around the sky becoming increasingly frustrated that you can't move the telescope the way your intuition tells you that you need to move it. Objects on land at great distances can be seen naturally (and readable) as if you were many times closer to the object. Objects in the sky appear as they appear in most star charts. For the first time ever, you will be able to see what you would expect resulting in excellent viewing satisfaction. In addition, the penta mirror has a special insert that is easily removed by backing out the eyepiece set screw and removing the insert to yield a 1.25" optical format receiver. 2. How-To-Use: Just like any traditional diagonal mirror, place the eyepieces directly into the rear of the Penta Mirror Assembly then place the Penta Mirror directly into the back of the telescope focusing tube, erecting lens or Barlow lens (See Intended Configuration Diagram). Fully Correct Image Reversed Image Upside-Down Image Upside-Down & Reversed Ima Insert Penta Mirror Please find below an image depicting how to attach the red dot finderscope and an image depicting a fully-attached unit. How-To-Attach: Place Finderscope Cylindrical Groove over Cylindrical Finderscope Mount Post until it clicks into place. Plastic Insert Adjustment Wheels Aligning and Using Red Dot Finderscope Remove plastic insert on bottom side of finderscope to allow battery to make connection with battery contact for power. Turn power switch on. Look through main telescope tube at low power and establish a well-defined stationary target. Looking through red dot finderscope, alternate tightening each adjustment wheel (at rear and left side of finderscope) until the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope tube. Selecting an Eyepiece: 1. You should always start viewing with the lowest power eyepiece, which in this case is the 20mm lens. Note: the base power of each eyepiece is determined by the focal length of the telescope objective lens, which for this model is 750 mm. A formula can be used to determine the power of each eyepiece: telescope OBJECTIVE lens focal length EYEPIECE focal length = MAGNIFICATION (e.g. Using the 20 mm lens, the calculation would look like this: 750 mm ÷ 20mm = 38x or 38 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 Penta Mirror. Note: The Penta Mirror Assembly when used in conjunction with the Barlow Lens and Eyepiece as shown on diagram will yield an effective doubling power of the magnification already achieved with the Barlow and Eyepiece configuration alone. The magnification calculation would look like this: 750 mm ÷ 20mm = 38 power. 38 power x 3=114 power. 38 x 3 x 2=228 power. (See Intended Configuration Diagram). 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). Fully extend focusing tube by turning Rack and Pinion Focusing Mechanism (15). 2. 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. Viewing Land-Based Objects: 1. As described above, the Erecting Lens will correct the normally upside down and reversed image so that you can easily enjoy observing land-based objects through your telescope. 2. Simply insert the Erecting Lens into the focusing tube of the telescope followed by the penta mirror, then insert an eyepiece into the penta mirror. (See Intended Configuration Diagram). 3. Repeat focusing directions as described above except that you will be looking through the Erecting Lens and eyepiece instead of just the eyepiece. Aligning Finderscope: Look through main telescope tube at low power and establish a well-defined stationary target. Looking through red dot finderscope, alternate tightening each adjustment wheel (at rear and left side of finderscope) until the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope tube. See finderscope page. Now, objects located first with the Finderscope (18) will be centered in the field of view of the main telescope. Balancing the Telescope 1. Arrange the telescope so that the telescope body is horizontal to the floor (latitude of 0°). Loosen the Right Ascension Lock (4). The telescope should now turn freely about the polar axis. Rotate the telescope about the polar axis so that the Counterweight Shaft (5) is parallel to the ground (horizontal). 2. Loosen the Counterweight Lock Screw (located on the counterweight), and slide the Counterweight (6) along the shaft until the telescope remains stationary without drifting rotationally about the polar axis. Tighten the Counterweight Lock Screw, locking the Counterweight into position. Cradle (20) 3. Now balance the telescope about the Declination Axis. Loosen the Declination Lock Knob (3) and the Cradle Lock Knobs (fig. 3) so that the telescope can slide freely inside the Cradles. Slide the telescope up or down inside the rings until Fig. 3 the telescope remains stationary without drifting rotationally about the Declination Axis. Tighten Cradle Lock Knobs. The telescope is now balanced. UNDERSTANDING THE EQUATORIAL MOUNT The Equatorial Mount is designed to move in any direction. It can be set to allow manual controls to track the movements of celestial bodies across the sky. This is referred to as diurnal movement; movement of celestial bodies in the direction opposite to that of the earth's rotation and around the earth's axis. By aligning the telescope's polar axis at celestial North, you will place the telescope in parallel with the earth's axis and thus be able to locate stars in the sky based on star atlas information. To compensate for your position on earth, the polar axis is set in one of three ways: · Set up the telescope at night. Loosen the Declination Lock Knob (3) and rotate the telescope around the declination axis until the arrow on the declination scale points to 90 degrees. Tighten the Declination Lock Knob. The telescope is now roughly in parallel with the polar axis. Loosen the Horizontal Axis Lock Knob (13) and turn the telescope until the objective end faces due north. This can be done by approximating the location of the pole star (Polaris or North Star) or by the use of a compass. True North is then found by directing the telescope at Polaris, as magnetic North is slightly away from true North. · Look up the latitude of your area in any geographical atlas. Loosen the Latitude Lock Knob (7) and set the latitude scale to the correct latitude for your area. Aim the Finderscope (18) at Polaris. You will probably notice that Polaris is not dead center in the Finderscope's field of view. This is probably because your telescope is not absolutely level with the ground. Loosen the Horizontal Axis Lock Knob (13) again and turn the telescope so that it is directly aimed at Polaris. Tighten both the Horizontal Axis Lock Knob and Latitude Lock Knob. Polaris is 1 degree from the North celestial pole. Therefore, the sighting of stars will have to be slightly adjusted as you locate them in the heavens. Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Occur Enjoying Your New Telescope 1. First determine your targeted object. Any bright object in the night sky is a good starting point. The Moon is a great starting point. 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 i ...
