User manual CELESTRON C100ED-RGT Supplementary Guide

[. . . ] The following is a supplemental addendum to the included instruction manual that explains the new features of Celestron's Advanced Series Telescopes. Please refer to this addendum for information concerning the new hand control features included with your telescope. Refer to the owner's manual for step-by-step instruction on assembling and using your telescope. The Advanced Series GT, computerized version of each telescope has a hand controller designed to give you instant access to all the functions that your telescope has to offer. With automatic slewing to over 40, 000 objects, and common sense menu descriptions, even a beginner can master its variety of features in just a few observing sessions. [. . . ] Press INFO to access information on the displayed planet. Press ENTER to slew to the displayed planet. Tour Mode The Advanced Series telescopes include a tour feature which automatically allows the user to choose from a list of interesting objects based on the date and time in which you are observing. The automatic tour will display only those objects that are within your set filter limits (see Filter Limits in the Setup Procedures section of the manual). To activate the Tour mode, press the TOUR key (6) on the hand control. The hand control will display the best objects to observe that are currently in the sky. · · · To see information and data about the displayed object, press the INFO key. To slew to the object displayed, press ENTER. To see the next tour object, press the Up key. Constellation Tour In addition to the Tour Mode, your telescope has a Constellation Tour that allows the user to take a tour of all the best objects in each of the 88 constellations. Selecting Constellation from the LIST menu will display all the constellation names that are above the user defined horizon (filter limits). Once a constellation is selected, you can choose from any of the database object catalogs to produce a list of all the available objects in that constellation. · · · To see information and data about the displayed object, press the INFO key. To slew to the object displayed, press ENTER. To see the next tour object, press the Up key. Direction Buttons The hand control has four direction buttons (3) in the center of the hand control which control the telescope's motion in Declination (north and south) and Right Ascension (east and west). The telescope can be controlled at nine different speed rates. Rate Button Pressing the RATE key (11) allows you to instantly change the speed rate of the motors from high speed slew rate to precise guiding rate or anywhere in between. Each rate corresponds to a number on the hand controller key pad. The number 9 is the fastest rate (3º per second, depending on power source) and is used for slewing between objects and locating alignment stars. The number 1 on the hand control is the slowest rate (. 5x sidereal) and can be used for accurate centering of objects in the eyepiece and photographic guiding. To change the speed rate of the motors: · · Press the RATE key on the hand control. The LCD will display the current speed rate. Press the number on the hand control that corresponds to the desired speed. The number will appear in the upper-right corner of the LCD display to indicate that the rate has been changed. The hand control has a "double button" feature that allows you to instantly speed up the motors without having to choose a speed rate. To use this feature, simply press the arrow button that corresponds to the direction that you want to move the telescope. While holding that button down, press the opposite directional button. This will increase the slew rate to the maximum slew rate. [. . . ] Parameters such as backlash compensation values, initial date and time, longitude/latitude along with slew and filter limits will be reset. The hand control will ask you to press the "0" key before returning to the factory default setting. Version - Selecting this option will allow you to see the current version number of the hand control and motor control software. The numbers indicate the hand control software version. For the motor control, the hand control will display two sets of numbers; the first numbers are for R. A and the second set are for DEC. [. . . ]
