[. . . ] Remove the Stabilizer Bar Mounting Screw (11) from the hardware pack and insert it into the opening at the base of the Vertical Stabilizer Bar (4). · Locate the Finderscope (1) with pre-assembled mounting bracket. Remove the two nuts located near the front of the telescope (closet to the eyepiece) and place the Finderscope and bracket assembly over the exposed screws. Replace the nuts, and securely tighten the Finderscope and bracket assembly in place. [. . . ] 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 will 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. During calm and crisp nights, the light/dark separation line on the moon (called the "Terminator") is marvelous at high power. You can see mountains, ridges and craters jump out at you due to the highlights. Similarly, you can move up to higher magnifications on the planets and nebulae. Star clusters and stars are best viewed through the low power no matter what. The recurring astronomical theater we call the night sky is an ever-changing billboard. Rather, the positions of the stars change not only hourly as they seem to rise and set, but also throughout the year. As the earth orbits the sun our perspective on the stars changes on a yearly cycle about that orbit. The reason the sky seems to move daily just as the sun and the moon "move" across our sky, is that the earth is rotating about its axis. As a result you may notice that after a few minutes or a few seconds depending on what power you are viewing at, the objects in your telescope will move. At higher magnifications especially, you will notice that the moon or Jupiter will "race" right out of the field of view. To compensate, just move the fine adjustment controls on your telescope to "track" it in the necessary path. Helpful Hints 1. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you've drawn a crowd with your new telescope. You'd be surprised how much more you'll see from your local lake or park when compared to a backyard in the city. Waiting until the object rises well above the horizon will provide a brighter and crisper image. [. . . ] Where do I find the Telescope Focal Length · The telescope focal length is the same focal length as the objective focal length. · Telescopes with power ranging from 25X to 50X can be used to view Star Clusters and Nebulae. The Lifetime Limited Warranty is an expression of our confidence in the materials and mechanical workmanship of our products and is your assurance of a lifetime of dependable service. If your telescope contains electrical components, these components are warranted to be free of defects in materials and workmanship for two years after the date of purchase. [. . . ]
