CGEM Series Manual - Celestron

Direction ButtonsThe hand control has four direction buttons (3) in the center of the hand control which control the telescope's motion inaltitude (up and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates.Rate ButtonPressing the RATE key (11) allows you to instantly change the speed rate of the motors from high speed slew rate to preciseguiding rate or anywhere in between. Each rate corresponds to a number on the hand controller key pad. The number 9 is thefastest 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 theeyepiece 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 inthe 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 aspeed rate. To use this feature, simply press the arrow button that corresponds to the direction that you want to move thetelescope. While holding that button down, press the opposite directional button. This will increase the slew rate to themaximum slew rate.The direction that a star moves in the eyepiece when a direction is pressed will change depending on which side of theMeridian the telescope tube is positioned. In order to change the direction of the arrow buttons, see Scope Setup Features laterin this section.1 = .5x 6 = 64x2 = 1x (sidereal) 7 = 1º / sec3 = 4x 8 = 2º / sec4 = 8x 9 = 5º / sec5 = 16xNine available slew speedsSetup ProceduresThe Hand Control contains many user defined setup functions designed to give the user control over the telescope's manyadvanced features. All of the setup and utility features can be accessed by pressing the MENU key and scrolling through theoptions:Tracking ModeThis allows you to change the way the telescope tracks depending on the type of mount being usedto support the telescope. The telescope has three different tracking modes:EQ NorthEQ SouthOffUsed to track the sky when the telescope is polar aligned in theNorthern Hemisphere.Used to track the sky when the telescope is polar aligned in theSouthern Hemisphere.When using the telescope for terrestrial (land) observation, thetracking can be turned off so that the telescope never moves.23
