[. . . ] Remove Main Tube Locking Nuts (3) from screws extending from bottom of Telescope Main Tube (2). Insert extended screws into holes in cradle of Easy Track® Mounting System. Remove plastic insert on bottom side of finderscope to allow battery to make connection with battery contact for power. 2 · · Look through main telescope tube at low power and establish a well-defined stationary target. [. . . ] The magnification calculation would look like this: 700 mm ÷ 12. 5mm = 56 power. After selecting the desired eyepiece, aim main telescope tube at a land-based target at least 200 yards away (e. g. Fully extend focusing tube by turning Rack and Pinion Focusing Mechanism (11). While looking through selected eyepiece (in this case the 12. 5 mm), slowly retract focusing tube by turning Rack and Pinion Focusing Mechanism until object comes into focus. As described above, the Erecting Lens will correct the normally upside down and reversed image so that you can easily enjoy observing land-based objects through your telescope. Simply insert the Erecting Lens into the focusing tube of the telescope, penta mirror into erecting lens, then insert an eyepiece into the erecting lens. Repeat focusing directions as described above except that you will be looking through the Erecting Lens and eyepiece instead of just the eyepiece. Aligning Finderscope: Look through main telescope tube at low power and establish a well-defined stationary target. Looking through red dot finderscope, alternate tightening each adjustment wheel (at rear and left side of finderscope) until the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope tube. Now, objects located first with the wide field Finderscope (14) will be centered in the field of view of the main telescope. Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Occur Enjoying Your New Telescope 1. The moon is a starting point that is sure to please the budding astronomer as well as the experienced veteran. When you have developed proficiency at this level, other objects become good targets. 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. 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. If you don't see an image after attempting to focus it in, you might consider aligning your finderscope again. Once you pass this step, you'll enjoy the time spent ensuring a good alignment. Every object you center in the finderscope will be easily found in the main telescope tube, which is important for continuing your exploration of the night sky. The low power eyepieces are perfect for viewing the full moon, planets, star clusters, nebulae, and even constellations. However, for more detail, try bumping up in magnification to higher power eyepieces on some of these objects. [. . . ] The power of your telescope can be determined by dividing the focal length of the objective lens by the focal length of the eyepiece. (For example: 1000 ÷ 25 = 40X) The telescope focal length is the same focal length as the objective focal length. Telescope focal lengths range from 600mm to 910mm on Bushnell telescopes. Telescopes with power ranging from 25X to 50X can be used to view Star Clusters and Nebulae. [. . . ]
