    PART V: Operating Your Telescope 5.1 Aligning and using the finderscope/red dot finder Aligning and using the finderscope These fixed magnification scopes mounted on the optical tube are very useful accesso- ries. When they are correctly aligned with the telescope, objects can be quickly located and brought to the center of the field.

    PART V: Operating Your Telescope • Open the battery cover by pulling it down (you can gently pry at the 2 small slots) and remove the plastic shipping cover over the battery(Fig.5.1.2b). • Turn on the Red Dot Finder by rotating the variable brightness control clockwise until you hear a “click”.

  • Page 18: Choosing The Appropriate Eyepiece

    PART V: Operating Your Telescope 5.3 Choosing the appropriate eyepiece • The magnification produced by a telescope is determined by the focal length of the eye- piece 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.

    PART VI: Observing the sky 6.1 Sky Conditions • 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 va- pour 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”...

    PART VI: Observing the sky 6.4 Cooling the Telescope • Telescopes require at least 10 to 30 minutes to cool down to outside air temperature. This may take longer if there is a big difference between the temperature of the telescope and the outside air.
