As you read this manual, the technical terms associated with telescopes will be made clear. Standard Equipment • Complete optical tube assembly with a 4.5" (114mm) diameter primary mirror, viewfinder mounting bolts with mounting nuts and rack-and-pinion focuser. Mirror focal length = 1000mm; f/8.8 • Equatorial mount with aluminum tripod and leg braces. • Accessories: MA 25mm (40x) eyepiece (1.25"O.D.), MA 12mm (83x) eyepiece (1.25"O.D.) 2x Barlow lens 5 x 24 viewfinder and bracket Counterweight with counterweight shaft Flexible cable controls for both telescope axes Accessory tray with mounting knob Astronomy software (separate instructions supplied in software package UNPACKING AND ASSEMBLY (Numbers in brackets below refer to Fig. 1) 1. Remove and identify the telescope’s components, using the listing above. 2. Attach the 3 aluminum tripod legs (6, Fig. 1f) to the base of the equatorial mount (15, Fig. 1g) with the 3 leg braces supports (32, Fig. 1f) facing inward. Three bolts each about 2.5"" long, with washers and wing nuts (35, Fig. 1g), are provided for this 32 purpose in a hardware package. Stand the telescope upright, spreading the tripod legs evenly apart so that the accessory tray can be positioned to attach to the 3 leg braces. 3. Use the provided 3 short screws, washers and bolts to attach the accessory tray (36, Fig. 1f) to the tripod. Line up one of the leg braces (32, Fig. 1f) between the opening of one of the tripod leg brace supports (33, Fig. 1f) on the tripod so that one of the short screws will be able to 33 pass through the holes of the leg brace support and the leg brace. Using a Phillips-head screwdriver, thread one of the short screws through the hole. Place a washer on the other end, followed by the matching nut. Tighten to a firm feel. Repeat this procedure until all 3 leg braces are mounted on the 3 leg brace supports. See Fig. 2. 4. To attach the accessory tray (36, Fig. 1f) to the leg braces (32, Fig. 1f), place the round accessory tray over the over mounting bolt hole (38, Fig. 1b). Threading the attachment knob into the the mounting hole on top of the tray and turning the knob clockwise. Tighten to a firm feel, but do not overtighten—you will need to remove the tray if you wish to collapse the tripod. To remove the tray, just rotate the knob counterclockwise and remove the knob. You can then lift and remove the tray. 5. Extend the sliding center portion of the adjustable height tripod leg to the desired length for all 3 legs. Lock the tripod legs by tightening the leg lock thumbscrew to a firm feel. See Fig. 3. 6. Holding the counterweight (5, Fig. 1a) firmly in one hand, slip the counterweight onto the counterweight shaft (6, Fig. 1a). Attach the counterweight and counterweight shaft, by supporting the unlocked Fig. 2: Tripod leg brace support assembly. Leg lock knob Sliding inner leg extension Fig. 3: Adjust the height of the tripod. counterweight firmly in one hand while threading the counterweight shaft into the base of the Declination axis of the telescope’s equatorial mount (41, Fig. 1a). Once firmly attached, slide the counterweight about 2 inches from the bottom of the counterweight shaft and secure it in place with – 7– the counterweight lock (7, Fig. 1a) of the counterweight. Note: If the counterweight ever slips, the secured threaded safety washer/screw (8, Fig. 1a) will not let the weight slide entirely off the counterweight shaft. Be certain that this safety washer/screw is always in place. 7. Attach the flexible cables (4, Fig. 1a) and (3, Fig. 1a and 1e), as shown. These cables are secured in place with a firm tightening of the thumbscrews located at the attachment ends of each cable. 8. Tilt the polar axis (10, Fig. 1c) of the telescope to roughly a 45° angle with the horizon. This tilt is accomplished by first loosening the latitude adjustment lock (11, Fig. 1a and 1e), adjusting the mount and firmly re-tightening the latitude control lock. 9. Remove the optical tube attachment thumbscrews (14, Fig. 1d) from the optical tube mounting bolts that are on the underside of the main optical tube (12, Fig. 1a). Then lay the telescope optical tube assembly onto the saddle plate (13, Fig. 1a) passing the mounting bolts through the holes in the saddle of the mount. Re-attach the attachment thumbscrews to the mounting bolts, and tighten to a firm feel. See Fig. 1d. 10. Attach the viewfinder bracket (20, Fig. 1a) to the telescope using the 2 thumbscrews provided (16, Fig. 1a). The bracket fits over the two small bolts. Thread the thumbscrews over the bolts and tighten to a firm feel. Slide the Viewfinder tube (24, Fig. 1a) into the bracket and loosely tighten the tube using the Viewfinder adjustment screws. Remove the Viewfinder dustcover (9, Fig. 1a). See “Aligning the Viewfinder” below. 11. Insert the 25mm eyepiece (13, Fig. 1) into the eyepiece holder (17, Fig. 1a). Secure the eyepiece in place by tightening the eyepiece holder thumbscrews (18, Fig. 1a) to a firm feel. ...
