User manual CELESTRON C60

[. . . ] This manual covers both the 76mm equatorial mount model and the 114mm models. The equatorial mount contains setting circles and slow motion cables to make it easier to locate and track astronomical objects. But, before your journey begins take time to read this manual to familiarize yourself with the operation and parts of your telescope. WARNING--NEVER LOOK AT THE SUN WITH YOUR TELESCOPE OR ITS FINDERSCOPE. [. . . ] The star pointer is powered by a long life 3volt lithium battery (#CR2032) located underneath the front portion of the Star Pointer. Like all finderscopes, the Star Pointer must be properly aligned with the main telescope before it can be used. This is a simple process using the azimuth and altitude control knobs located on the side and bottom of the Star Pointer. The alignment procedure is best done at night since the LED dot will be difficult to see during the day. To turn on the Star Pointer, rotate the variable brightness control clockwise until you here a "click". To increase the brightness level of the red dot, continue rotating the control knob about 180º until it stops. Locate a bright star or planet and center it in a low power eyepiece in the main telescope. With both eyes open, look through the glass window at the alignment star. If the Star Pointer is perfectly aligned, you will see the red LED dot overlap the alignment star. If the Star Pointer is not aligned, take notice of where the red dot is relative to the bright star. Without moving the main telescope, turn the Star Pointer's azimuth and altitude alignment controls (#4 & #6) until the red dot is directly over the alignment star. 2. The right ascension setting circle does not move as the telescope moves in right ascension and thus it must by aligned each time you want to use it to find a new object. However, you do not need to use a bright star each time but you can use the object you are currently observing. First move the telescope in declination to the correct declination coordinate. Then move the telescope in right ascension until the indicator points to the correct coordinate. After moving the telescope to the correct celestial coordinates, look through the lower power eyepiece to see if you have located the object you wish to view. If the object is not visible in the eyepiece, gradually pan the telescope, using the right ascension and declination cables, until the object is visible. 5. 6. 5. MAGNIFICATION (POWER) The magnification (or power) of a telescope is variable depending upon the focal length of the eyepiece being used along with the focal length of the telescope. If you purchased one of the 76mm diameter models, your telescope has a focal length of 700mm. To calculate the magnification we use the following formula: Magnification = FL(telescope) FL(eyepiece) where FL(telescope) is the focal length of the telescope and FL(eyepiece) is the focal length of the eyepiece. There are numerous optional eyepieces that are available to expand your range of magnification. There are various types of eyepieces of varying quality to choose from. [. . . ] A map of the night sky, oriented by month and day, rotates within a depiction of the 24 hours of the day, to display exactly which stars and planets will be visible at any given time. Celestron Planispheres come in three different models, to match the latitude from which you're observing: Solar Filters (#94133) - The Celestron AstroSolar® filters are safe and allow you to see sunspots as they move across the solar disk. T-Adapter (#94177) - T-Adapter (with additional T-Ring) allows you to attach your SLR camera to the rear cell of your Celestron telescope. This turns your telescope into a high power telephoto lens perfect for terrestrial photography and short exposure lunar and filtered solar photography.
