[. . . ] The hand control will display all solar system objects that are above the horizon: · · · Use the Up and Down keys to select the planet that you wish to observe. Press ENTER to slew to the displayed planet. To allow the Sun to be displayed as an option in the database, see Sun Menu in the Utilities section of the manual. Tour Mode The NexStar includes 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. The NexStar 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 see the next tour object, press the Down key. Constellation Tour In addition to the Tour Mode, the NexStar telescope has a Constellation Tour that allows the user to take a tour of all the best objects within a particular constellation. 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 see the next tour object, press the Up key. 19 Direction Buttons The NexStar has four direction buttons in the center of the hand control which controls the telescope motion in altitude (up and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates. 1 2 3 4 5 = = = = = 2x 4x 8x 16x 32x 6 7 8 9 = = = = . 5º / sec 1º / sec 2º / sec 4º / sec Nine available slew speeds 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. The number 9 is the fastest rate (approximately 4º 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: · · Press the RATE key on the hand control. 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. When using the Up and Down buttons on the NexStar 60 and 80, 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 Star Pointer, you may need to press the opposite directional button to make the telescope move in the correct direction. Set Up Procedures The NexStar contains many user defined setup functions designed to give the user control over the telescope's many advanced features. All of the set up and utility features can be accessed by pressing the MENU key and scrolling through the options: Tracking Mode Once the NexStar is aligned the tracking motors will automatically turn on and begin tracking the sky. However, the tracking can be turned off for terrestrial use: Alt-Az This is the default tracking rate and is used when the telescope has been properly aligned.
