[. . . ] By simply attaching the accessory finderscope and eyepiece, you will be ready to explore. Remove Reflector Telescope Assembly (2) and Finderscope (7) from carton. Remove nuts located near the Rack & Pinion Focusing Mechanism (1) on Reflector Telescope Body (2). Attach Finderscope (7) to Reflector Telescope Body (2) by inserting the bolts extending from the Reflector Telescope Body (2) into the holes in the base of the Finderscope (7). [. . . ] 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. In other words, not the same movie plays all the time. 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. Your telescope is a very sensitive instrument. 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. If possible view from a location that has relatively few lights. This will allow you to see much fainter objects. You'd be surprised how much more you'll see from your local lake or park when compared to a backyard in the city. Using your telescope out a window is NEVER recommended. View objects that are high in the sky if possible. Waiting until the object rises well above the horizon will provide a brighter and crisper image. [. . . ] Since telescopes are used for astronomical viewing orientation is not important. The image in the finderscope will also be reversed. · The power of your telescope can be determine by dividing the focal length of the objective lens by the focal length of the eyepiece. The eyepiece focal 2. How do I determine the power my telescope ? length is the number printed on the eyepiece. [. . . ]
