[. . . ] VOYAGER® 4. 5 INCH REFLECTOR TELESCOPE MODEL 78-9540 8. 7. 1. 2. 5. 13 . 6. 3 4. 12 . Horizontal Axis Lock Knob Thank you for purchasing the Bushnell Voyager Telescope!Your new telescope has been designed and crafted with the highest standards so that you may have years of enjoyment and use out of this wonderful window to the heavens. [. . . ] 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 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. 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. The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscope's cross hairs. Provided you did a reasonable job aligning the finderscope, a quick look through the main telescope tube at low power should reveal the same image. With the lowest power eyepiece (the one with the largest number printed on it) you should be able to focus the same image that you saw through the finderscope. Avoid the temptation to move directly to the highest power. The low power eyepiece will give you a wider field of view, and brighter image--thus making it very easy to find your target object. At this point with a focused image in both scopes, you've passed the first obstacle. [. . . ] Astronomers refer to crisp, clear nights as nights of "good seeing. " 2. 3. Your Bushnell telescope can bring the wonders of the universe to your eye. While this manual is intended to assist you in the set-up and basic use of this instrument, it does not cover everything you might like to know about astronomy. The first thing you need to do is get a very simple star chart and a flashlight with a red bulb or red cellophane over the end. [. . . ]
