Attaching the Optical Tube You are now ready to put the telescope optical tube (c) onto the equatorial mount (f). 1. Slightly loosen the screws that hold the mounting rings on the telescope in place. 2. Slide the rings apart so that each is at the same distance as the holes in the mounting platform. 3. Place the telescope tube on the mount so that the treaded post at the bottom of the tube rings go through the holes on the mounting platform. 4. Thread a wing nut onto the end of the threaded posts and tighten to secure the tube to the mount. 5. Tighten the screws that hold the mounting rings in place. This will keep the telescope from sliding back and forth in the mounting rings. Attaching the Accessories Your telescope comes with the following accessories: • 20mm eyepiece 1¼" • 4mm eyepiece 1¼ " • 3x Barlow Lens 1¼" • 5x24 finderscope • The Sky® L1 Planetarium software 1. Remove the caps from the focuser draw tube (o). 2. Place the chrome barrel end of the eyepiece into the focuser. Lock it into place with the thumb screw on the side of the focuser. 3. Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see Magnification section of the manual). To use the barlow lens, insert the barlow lens directly into the focuser. Then start by using the low power eyepiece such as the 20mm, and insert it directly into the barlow lens. . Attaching the Finderscope 1. Remove the two small, silver thumbscrews located on top of the telescope tube. See Figure 2. 2. Place the finderscope bracket over the two holes in the telescope tube, lining up the holes on the finderscope bracket with those in the telescope tube. Insert the thumbscrews through the finderscope bracket and thread them into the telescope tube. Using your Telescope Moving Your Telescope: To change the direction your telescope is pointing: Figure 2 1. To move the telescope in declination (north/south) there are two options. For large and quick movements, loosen the declination knob (see figures 8) when moving the telescope and then tighten the knob when you are near the position you want. For very small movements and fine adjustments, use the declination cable. The declination cable has a range of about 30° and if you come to the stop at the end of its travel, do not try to force movement when the declination cable has reached the stop. Instead loosen the declination knob and manually move the telescope in declination until you pass the object in the opposite direction. Then tighten the knob and reverse the direction of the declination cable. 5
