[. . . ] It can be set to allow manual controls to track the movements of celestial bodies across the sky. This is referred to as diurnal movement; movement of celestial bodies in the direction opposite to that of the earth's rotation and is around the earth's axis. By aligning the telescope's polar axis at celestial North, you will place the telescope in parallel with the earth's axis and thus be able to locate stars in the sky based on star atlas information. To compensate for your position on earth, the polar axis is set in one of three ways: · Set up the telescope at night. Loosen the Declination Lock Knob (18) and rotate the telescope around the declination axis until the arrow on the declination scale points to 90 degrees. The telescope is now roughly in parallel with the polar axis. Loosen the Horizontal Axis Lock Knob (13) and turn the telescope until the objective end faces due north. This can be done by approximating the location of the pole star (Polaris or North Star) or by the use of a compass. True North is then found by directing the telescope at Polaris, as magnetic North is slightly away from true North. Look up the latitude of your area in any geographical atlas. Loosen the Latitude Lock Knob (22) and set the latitude scale to the correct latitude for your area. You will probably notice that Polaris is not dead center in the Finderscope's field of view. This is probably because your telescope is not absolutely level with the ground. Loosen the Horizontal Axis Lock Knob (13) again and turn the telescope so that it is directly aimed at Polaris. Tighten both the Horizontal Axis Lock Knob and Latitude Lock Knob. Polaris is 1 degree from the North celestial pole. Therefore, the sighting of stars will have to be slightly adjusted as you locate them in the heavens. · · Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Occur Enjoying Your New Telescope 1. First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When you have developed proficiency at this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take. [. . . ] www. bushnell. com ANSWERS TO COMMONLY ASKED QUESTIONS 1. The image I see in the telescope is upside down and reversed from right to left ?· An upside-down and reversed image is a common characteristic of most astronomical telescopes. Since telescopes are used for astronomical viewing orientation is not important. [. . . ]
