Fine Adjustment Knobs: 2 pc. TELESCOPE ASSEMBLY 1. Remove telescope from carton and identify all components. READ THROUGH ASSEMBLY INSTRUCTIONS BEFORE YOU ASSEMBLE YOUR TELESCOPE 2. Set-Up Tripod, Mount and Accessory Tray • Select one Tripod Leg (9) and extend the Tripod Leg Middle Section (10). Using Tripod Leg Lock Screws (13) included in the hardware pack, insert the Tripod Leg Lock Screw into the lower brackets on the Tripod Leg (9). Tighten the Tripod Leg Lock Screws so that the Middle Section is securely in place. Repeat on remaining two legs. • Locate the Equatorial Mount (22). Note: Before assembling tripod legs to Equatorial Mount make sure the Accessory Tray Braces (11) face inward. Locate the long bolts and washers from the hardware pack. Position the mount over the Tripod Leg as shown (fig. a). 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 (9). 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 (12). Using the accessory tray bolts, wingnuts and washers ( 3-_” bolts, 6-_ washers and 3 - wingnuts) connect the Accessory Tray to the Accessory Tray Braces (11). 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 Finderscope • Locate the Finderscope(20) with pre-assembled Finderscope Mount (21). 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. 2. Attach Telescope Main Tube • Locate the Telescope Main Tube (2). Remove the wingnuts that are attached to the long screws protruding from beneath the telescope. Position the long screws over the two holes in the Equatorial Mount (22) and carefully secure the Telescope Main Tube to the Equatorial Mount. 3. Attach Control Cables, Counterweight and Eyepieces • Locate the Fine Adjustment Cables (14) and the fine adjustment knobs (located in the hardware pack). Remove the black “Phillips” head screw at the end of the cables. Place the knobs over the adjustment cable and position so that the holes are aligned. Replace screws and secure tightly. fig. a • Loosen the silver screws located at the opposite end of the Fine Adjustment Cables (14). Now, 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). • Locate the Counterweight (6) and Counterweight Shaft (5). Loosen the thumb screw located on the Counterweight and slide the Counterweight onto the Counterweight Shaft and tighten thumb screw to secure the Counterweight. Thread the Counterweight Shaft into the hole located directly below the Declination Lock Knob (3). Make sure that the shaft 15 is securely locked into mount. • Locate Eyepiece (17) and Diagonal Mirror (16). Carefully place Eyepiece into Diagonal Mirror as shown (fig. b) 16 fig b. Your Bushnell telescope is now ready to be used. To obtain the fullest enjoyment from your telescope, please refer to the additional information below. III. 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 is around the earth’s axis. By aligning the telescope’s polar axis at celestial North,...
