TELESCOPE ASSEMBLY 1. Remove all components from the carton and identify all components. READ THROUGH ASSEMBLY INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE 2. Set-Up Tripod, Mount and Accessory Tray · Select one Tripod Leg (5) and extend the Tripod Leg Middle Section (6). Using Tripod Leg Lock Screws (9) included in the hardware pack, insert the Tripod Leg Lock Screw into the lower brackets on the Tripod Leg. Tighten the Tripod Leg Lock Screws so that the middle section is securely in place. Repeat on remaining two legs. · Locate the Altazimuth Yoke Mount (3). Note: Before assembling tripod legs to Altazimuth Yoke Mount, make sure the Accessory Tray Braces(7) face inward. Locate the long bolts and washers from the hardware pack. Position the mount over the Tripod Leg (5) as shown (fig. 1). and align the holes in the Tripod Leg with the holes in the mount. Insert the bolts through the holes at the top of a Tripod Leg. A washer should be positioned on both outer sides of the Tripod Leg. Attach a wing nut to the bolt, but do not tighten it all the way. Repeat on the remaining two Tripod Legs. Once you have attached all Tripod Legs to the mount, securely tighten all wing nuts. · Locate the Accessory Tray (8). Using the accessory tray bolts, wingnuts and washers ( 3-_” bolts, 6-_ washers and 3 - wingnuts) connect the Accessory Tray to the Accessory Tray Braces (7). Start with one Tripod Leg and attach wingnut. 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. 1. Attach Telescope and Finderscope · Locate Telescope Main Tube (2). Secure telescope to Altazimuth Yoke Mount (3) by removing Altitude Lock Knobs (17) and positioning the telescope between yoke. Carefully replace the Altitude Lock Knobs and remove lens cover from 60mm Objective Lens (1) · Locate the Finderscope(16) with pre-assembled Finderscope Mount (13). Remove the two nuts located near the back of the Telescope Main Tube (2) and place the Finderscope and Mount assembly over the exposed screws. Replace the nuts, and securely tighten the Finderscope Mount in place. 1. Attach Eyepiece and Diagonal Mirror · Locate an Eyepiece (12) (either the 5mm or 20mm) and Diagonal Mirror (11). Attach the Diagonal Mirror as shown (fig. 2). Insert an Eyepiece into the Diagonal Mirror. Your Bushnell Telescope is now ready to be used. To obtain the fullest enjoyment from your telescope, please refer to the additional information below. fig. 1 fig 2. 12 11 10 HOW TO USE YOUR NEW TELESCOPE Astronomical telescopes are designed such that the image you see will appear UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. For land-based viewing an “Erecting Lens” is used to properly re-orient the image. 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 lens, which for this model is 700 mm. A formula can be used to determine the power of each eyepiece lenses: telescope OBJECTIVE lens focal length EYEPIECE focal length = MAGNIFICATION (e.g. Using the 20 mm lens, the calculation would look like this: 700 mm . 20mm = 35x or 35 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 105x or 105 power. (35 x 3 = 105x or 105 power) 3. Also included with this telescope is an Erecting lens. An Erecting lens is used to view land-based object where the correct image orientation is important. The Erecting lens re-orients the telescope image so that the image you see is properly oriented. Place your Erecting lens between the focusing tube and the eyepiece (fig. 3). It is not recommended to use the Diagonal Mirror (11) with the Erecting lens. The Diagonal Mirror will make the erected image appear to be “flipped” depending on the orientation of the diagonal mirror- relative to the te...
