[. . . ] PowerSeeker 114 INSTRUCTION MANUAL #21045 INTRODUCTION Congratulations on your purchase and welcome to the Celestron world of amateur astronomy. Some of the terms and parts described in these instructions may be new to you, so a few commonly used terms you'll want to be familiar with are defined below. Equatorial mount ­ a type of mounting that allows the telescope to be aligned with the earth's axis in order to track the motion of the sky. Focal length - the distance from the optical center of the lens to the point where the incoming light rays converge, creating a clear, focused image. [. . . ] Locate a distant daytime object and center it in a low power eyepiece in the main telescope. Look through the finderscope and take notice of the position of the same object. Without moving the main telescope, turn the adjustment thumb screws located around the finderscope bracket until the crosshairs of the finder are centered on the alignment object. Finding Objects In order to use the equatorial mount's setting circles, the mount must first be aligned with the earth's axis of rotation. Turn the latitude adjustment screw (8) located at the rear of the mount to adjust the angle of the mount. Look at the latitude scale and move the mount to the latitude of your location. This only has to be done once unless you take the telescope to a different location. For example, Los Angeles, California is located at about 34º. If you do not know your latitude, it can be found on most road atlases of your area. Declination Setting Circle Right Ascension Setting Circle To change the direction your telescope is pointing: 2. To move the telescope in declination (north/south) there are two options. For large and quick movements, loosen the declination locking screw (20) and manually move the telescope, then tighten the knob when you are near the position you want. For very small movements and fine adjustments, use the declination slow motion control (7). The declination cable has a range of about 30°. Do not try to force movement when the declination cable has reached the stop. Latitude Scale Figure 1-5 3. To move the telescope in right ascension (east/west) there are two options. For large and quick movements, loosen the right ascension locking screw (located above the setting circle) and manually move the telescope, then tighten the screw when you are near the position you want. For very small movements and fine adjustments, use the right ascension slow motion control (17). The telescope should be properly balanced in order for it to move smoothly in both axes. Proper balance is essential if using an optional motor drive for accurate tracking. To balance the right ascension axis, move the counterweight bar so it is parallel (horizontal) to the ground. Slowly release the right ascension locking screw and see if the optical tube moves. If the optical tube moves, then slide the counterweight up or down the counterweight bar until the optical tube remains stationary in the parallel position to the ground. When this happens, make sure the counterweight lock (located on the tip of the counterweight bar) is tight. Focusing 1. Once you have found an object in the telescope, turn the focusing knob (21) until the image is sharp. [. . . ] This useful guide also includes beautiful constellation paintings, photographs, and clear, concise descriptions of stars, the planets, the sun, the moon, comets, black holes, galaxies and more. 9 CELESTRON TWO YEAR WARRANTY a.
