Congratulations on your purchase of an Orion telescope. Your new SkyView Pro 6LT EQ is designed for,
high-resolution viewing, and astrophotography of astronomical objects. [. . . ] lock lever and rotate the telescope until the right ascension value from the star atlas matches the reading on the R. A. Most setting circles are not accurate enough to put an object dead-center in the telescope's eyepiece, but they should place the object somewhere within the field of view of the finder scope, assuming the equatorial mount is accurately polar aligned. Use the slow-motion controls to center the object in the finder scope, and it should appear in the telescope's field of view. The setting circles must be re-calibrated every time you wish to locate a new object. Do so by calibrating the setting circles for the centered object before moving on to the next one. Beginners occasionally experience some confusion about how to point the telescope overhead or in other directions. In Figure 1 the telescope is pointed north as it would be during polar alignment. But it will not look like that when the telescope is pointed in other directions. Let's say you want to view an object that is directly overhead, at the zenith. Remember, once the mount is polar aligned, the telescope should be moved only on the R. A. lock lever and rotate the telescope on the right ascension axis until the counterweight shaft is horizontal (parallel to the ground). lock lever and rotate the telescope until it is pointing straight overhead. What if you need to aim the telescope directly north, but at an object that is nearer to the horizon than Polaris?You can't do it with the counterweights down as pictured in Figure 1. Again,
you have to rotate the scope in right ascension so that the counterweight shaft is positioned horizontally. Then rotate the scope in declination so it points to where you want it near the horizon. To point the telescope directly south, the counterweight shaft should again be horizontal. Then you simply rotate the scope on the declination axis until it points in the south direction. To point the telescope to the east or west, or in other directions, you rotate the telescope on its right ascension and declination axes. Depending on the altitude of the object you want to observe, the counterweight shaft will be oriented somewhere between vertical and horizontal. Figure 12 illustrates how the telescope will look when pointed at the four cardinal directions: north, south, east and west.
7. Collimating (Aligning The Mirrors)
Collimating is the process of adjusting the mirrors so they are perfectly aligned with one another. [. . . ] Wipe the mirror under water with clean cotton balls, using extremely light pressure and stroking in straight line across the mirror. Any particles on the surface can be swabbed gently with a series of cotton balls, each used just one time. Dry the mirror in a stream of air (a "blower bulb" works great), or remove any stray drops of water with the corner of a paper towel. Cover the mirror surface with Kleenex, and leave the mirror in a warm area until it is completely dry before reassembling the telescope.
