It is a good idea to lay all the parts out in front of you before assembly. [. . . ] 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. Any bright object in the night sky is a good starting point. 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. Saturn, Mars, Jupiter, and Venus are good second steps to take. 2. 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. 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. [. . . ] It's because you are looking through a considerable more amount of atmosphere than you would directly overhead. (Note: If objects high in the sky are distorted or wavy, you are probably viewing on a very humid night. ) During nights of unstable atmosphere, viewing through a telescope can be frustrating if not impossible. Star Clusters--View millions of stars densely packed in a cluster that resembles a ball. Galaxies--One of the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. [. . . ]
