ECLIPSE 114
WARNINGS •Do not use telescope or finderscope to look at the sun without an appropriate solar filter. •Make sure no screws are loose before using telescope. •Do not drop, shake, or throw your telescope as doing so may damage the telescope or people around you. •Objects in telescope may be farther away than they appear. •Eyepieces intended for external use only. •Don’t worry, be happy...

Latiutude Adjustment Screw CARE OF YOUR TELESCOPE A telescope is carefully aligned during construction and great care should be taken to maintain this alignment over the life of the telescope.
TELESCOPE ASSEMBLY 1. Extend tripod legs to comfortable working height and tighten wingnuts to ensure stability. Separate tripod legs and ensure that the legs are extended to equal heights. The top of the tripod should be level to ensure stability when mounting telescope. 2. Remove mount base screw. Insert bottom of mount assembly into tripod mounting hole. Replace mount base screw below tripod mounting plate and tighten to secure mount to tripod. 3.
. Tighten all setscrews on the mount assembly to prevent movement of mount. Tighten the set screw on the counterweight to prevent movement of weight on balance shaft. Screw threaded end of balance shaft into the threaded receptacle opposite the telescope mounting bracket on the upper part of the mount. Tighten balance shaft for stability. 7. Remove wingnuts and washers from the bottom of telescope mounting belt. Insert exposed bolt into hole on top of mount.
SOME NOTES ON VIEWING Never look at the sun without using a solar filter. When using a solar filter, do not remove the full lenscap, view only through the small opening in the lenscap. Looking at the sun without proper use of a solar filter can cause permanent eye damage. When looking through the telescope, the image will appear to be upsidedown and inverted. This results from the optical system design and is normal. This can be corrected by using a Schmidt or erecting prism when viewing.
USING THE CLOCK DRIVE The clock drive included with your telescope is designed to track the movement of stars. It will help keep stars in your field of view during long periods of viewing as long as the telescope is properly polar aligned and the clock drive is properly used. Do not be alarmed if you turn on the clock drive and do not see the telescope moving. Stars appear to move very slowly and the telescope may not apear to move over a short period of time.
BEGINNING OBSERVATION For beginning observation, the moon is one of the easiest and most enjoyable objects to view. You can acquaint yourself with the movements of the telescope by simply pointing the telescope at the moon and using the various adjustments to move the telescope. To point the telescope at the moon, loosen the R.A. and Dec. clamps (the thumbscrews located nearest the Hour Circle and Declination Circle on the mount), then gently move the optical tube assembly until it points at the moon.
ADVANCED OBSERVATION STAR CHARTS AND SETTING CIRCLES Star charts and setting circles will allow you to find the location of any known celestial objects viewable by your telescope. By using the measurements listed on the mount and the coordinates provided in a star chart, you will be able to find stars, planets, nebulae, and galaxies for exploration with your telescope.
NORTHERN HEMISPHERE POLAR ALIGNMENT 1. To align your telescope in the Northern Hemisphere, first find the location of Polaris in the night sky. You can easily find polaris by using the Big Dipper to “point” at Polaris. The two stars which make up the edge of the dipper in the Big Dipper will roughly “point” at Polaris. You can also use the star at the end of the handle of the Big Dipper and the star on the edge of the shallower end of Cassiopeia to draw a line through Polaris. The illustration shows this.
SOUTHERN HEMISPHERE & STAR DRIFT POLAR ALIGNMENT Polar alignment in the Southern Hemisphere is more difficult that in the Northern Hemisphere because there is no corresponding pole star to use for alignment in the Southern Hemisphere. Polar aligning in the Southern Hemishpere is a two part process because of this. A rough alignment must first be made based on your viewing location. Then, a star drift alignment should be made to fine tune your alignment.
2. Find a bright star in the viewfinder of your telescope and use the R.A. and Dec. adjustment cables to center it in the crosshairs. Work up to your most powerful eyepiece, centering the star in the viewfinder each time you replace the eyepiece. 3. Engage the clock drive by tightening the thumbscrew which connects it to the R.A. axis of the mount. Turn on the clock drive, ensuring that it is set to the correct hemisphere setting. Let the clock drive run for about 5 minutes. 4.
FINDING CELESTIAL OBJECTS Once your telescope is polar aligned, you must set the hour circle in order to use the measurements listed on the mount to find celestial objects. Once the hour circle is properly set, you will be able to use the coordinates listed on star charts to find objects for viewing in the night sky. Setting the hour circle will require that you recognize and be able to find a star other than the ones used for alignment of the telescope.
ASTRONOMY FOMULAE Magnification To determine the magnification of a telescope and eyepiece combination, divide the telescope focal length be the eyepiece focal length. Magnification (x) = Telescope Focal Length (mm)/Eyepiece Focal Length (mm) Ex: 6.3mm Eyepiece with a 114x1000mm telescope. Magnification = 1000mm/20mm Magnification = 50x Focal Ratio To determine the focal ratio of a telescope, divide the focal length of the telescope by the aperture.
ASTRONOMY TERMINOLOGY DECLINATION (DEC.) - The astronomical equivalent of latitude. Declination describes the angle of a celestial object above or below the celestial equator. The sky over the northern hemisphere has a positive declination. The sky over the Southern hemisphere has a negative declination. For example, Polaris (the North Star) which lies nearly directly over the North Pole, has a declination value of 90°. RIGHT ASCENSION (R.A.) - The astronomical equivalent of longitude.
TELESCOPE TERMINOLOGY OBJECTIVE - The objective is the front lens of a telescope. The measurement listed for objective lenses is the diameter of the lens. A larger objective allows more light to enter a telescope and provides a brighter image. The objective diameter is also sometimes referred to as the aperature of a telescope. FOCAL LENGTH - The focal length of a telescope is the distance from the point where light enters a telescope (the objective) to the point where the image is in focus.
