Celestron CGX 700 Maksutov Cassegrain Telescope CGX Mount - Page 19

Direction Buttons The hand control has four direction buttons in the center of the hand control which control the telescope motion in altitude (up and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates. 1 = 2x 2 = 4x 3 = 8x 4 = 16x 5 = 32x 6 = .3° / sec 7 = 1° / sec 8 = 2° / sec 9 = 4° / sec Menu Button The CGX mount contains many user-defined setup functions designed to give the user control over the telescopes many features. All of the setup and utility features can be accessed by pressing the MENU key and scrolling through the options below. Tracking Menu Tracking Mode - This allows you to change the way the telescope tracks depending on the type of mount being used to support the telescope. The telescope has three different tracking modes: Motor Speed Button Pressing the MOTOR SPEED button (12) 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 (approximately 4° 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 (2x sidereal) and can be used for accurate centering of objects in the eyepiece. To change the speed rate of the motors: • EQ North - Used to track the sky when the telescope is polar aligned in the Northern Hemisphere. • EQ South - Used to track the sky when the telescope is polar aligned in the Southern Hemisphere. • Off - When using the telescope for terrestrial (land) observation, the tracking can be turned off so that the telescope never moves. Tracking Rate - In addition to being able to move the telescope with the hand control buttons, your telescope will continually track a celestial object as it moves across the night sky. The tracking rate can be changed depending on what type of object is being observed: • Press the MOTOR SPEED 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 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 speed to the maximum slew rate. When using the UP and DOWN buttons on the hand control, the slower slew rates (6 and lower) move the motors in the opposite direction than the faster slew rates (7- 9). This is done so that an object will move in the appropriate direction when looking into the eyepiece (i.e., pressing the up arrow button will move the star upwards in the field of view of the eyepiece). However, if any of the slower slew rates (rate 6 and below) are used to center an object in the starpointer, you may need to press the opposite directional button to make the telescope move in the correct direction. • Sidereal - This rate compensates for the rotation of the Earth by moving the telescope at the same rate as the rotation of the Earth, but in the opposite direction. When the telescope is polar aligned, this can be accomplished by moving the telescope in right ascension only. • Lunar - Used for tracking the Moon when observing the lunar landscape. • Solar - Used for tracking the Sun when solar observing with the proper filter. View Time-Site Menu This menu displays the current time and longitude/latitude downloaded from the optional SkySync GPS receiver. It will also display other relevant time-site information like time zone, daylight saving and local sidereal time. Local sidereal time (LST) is useful for knowing the right ascension of celestial objects that are located on the Meridian at that time. View Time-Site will always display the last saved time and location entered while it is linking with the GPS. Once current information has been received, it will update the displayed information. If GPS is switched off or not present, the hand control will only display the last saved time and location. Help Button In future firmware updates, this button will offer troubleshooting tips. For your convenience, it currently functions as a shortcut to the Messier Catalog. The Hand Control Menu The "Hand Control" menu allows you to customize certain features of the NexStar+ hand control. To access this menu, press the MENU button (#7 on the keypad) and use the scroll buttons to select "Hand Control" and press ENTER. ENGLISH | 19
