[. . . ] READ THROUGH ASSEMBLY INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE 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. [. . . ] 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. 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. 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. Barlow lenses are used to double or triple the power of your telescope. 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) 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. 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 telescope. 3. Erecting Lens or Barlow Lens 12 10 Focusing Telescope: 1. After selecting the desired eyepiece, aim Main Telescope Tube (2) at a land-based target at least 200 yards away (e. g.
