Page 5: Operating Your Telescope
OPERATING YOUR TELESCOPE Fig.a This telescope has an altitude(up-down)- Altitude adjustment azimuth(left-right) mount to control telescope movements. Loosen the azimuth lock knob to make left-right direction movements then tighten to lock. Loosen the altitude lock knob Altitude fine adjustment to make course up-down changes. Altitude fine adjustments can be made by rotating the knurled wheel on the altitude fine adjustment rod after tightening the altitude... - 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
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"... -
