  • Page 3 TRIPOD SET UP ASSEMBLING TRIPOD LEGS (Fig. 1) Fig. 1 1) Gently push middle section of each tripod leg at the top so that the pointed foot protrudes below the tripod clamp. 2) Insert tripod lock screws into the thread holes on the side of the tripod clamp without over-tightening.
  • Page 4 FINDERSCOPE ASSEMBLY Fig. 7 Locate the finderscope bracket and carefully remove the rubber-o-ring from it. Position the o-ring into groove on the finderscope tube (Fig.7). Fig. 8 Slide the finderscope bracket into the mounting slot and tighten the screw to hold the bracket in place (Fig.8). Loosen the two adjusting screws on the bracket.
  • Page 5 OPERATING YOUR TELESCOPE Fig.a Azimuth locking knob This mount has controls for movement in altitude (up-down) and azimuth (left-right). Coarse azimuth movement is controlled by a locking knob located Altitude fine adjustment near the tripod head for left-right rotation. Loosen the knob to make large direction changes then lock it for fine adjustments.
  • Page 6 Pointing an altitude-azimuth (alt-az) mounted telescope is relatively easy. With the mount level, you can swivel the telescope around on a plane parallel to your horizon and then tilt it up and down from there (Fig.c). You can think of it as turning your telescope in azimuth until it is facing the horizon below a celestial object and then tilting it up to the object's altitude.
  • Page 7 The magnification produced by a telescope is determined by the focal length of the eyepiece that is used with it. To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you are going to use. For example, a 10mm focal length eyepiece will give 80X magnification with an 800mm focal length telescope.
  • Page 8 OBSERVING THE SKY Sky conditions are usually defined by two atmospheric characteristics, seeing, or the steadiness of the air, and transparency, light scattering due to the amount of water vapour and particulate material in the air. When you observe the Moon and the planets, and they appear as though water is running over them, you probably have bad "seeing"...
