Selecting an Object Once the telescope is properly aligned, you can choose an object from any of the catalogs in the NexStar+ hand control's database. The hand control has a key designated for each category of objects in its database; Solar System objects, Stars and Deep Sky objects. • Solar System - The Solar System catalog will display all of the planets (and Moon) in our Solar System that are currently visible in the sky. To allow the Sun to be displayed as an option in the database, see Allow Sun option in the Database Setup section of the manual. • Stars - The Stars catalog displays custom lists of all the brightest stars, double (binary) stars, variable stars, constellations and selected asterisms. • Deep Sky - The Deep Sky catalog displays a list of all of the best Galaxies, Nebulae and Clusters, as well as the complete Messier and select NGC objects. There is also an alphabetical list of all deep sky objects in order by their common name. Use the SCROLL keys to scroll through the catalogs to find the object you wish to view. When scrolling through a long list of objects, holding down either the UP or DOWN key will allow you to scroll through the catalog at a rapid speed. Slewing to an Object Once the desired object idisplayed on the hand control screen, you have two options: • Press the OBJECT INFO Key. This will give you useful information about the selected object such as magnitude, constellation and extended information about the most popular objects. - Use the UP/DOWN arrow buttons to scroll through the displayed object info. - Use the BACK button to return to the object database. • Press the ENTER Key. This will automatically slew the telescope to the coordinates of the object displayed on the hand control. While the telescope is slewing to the object, the user can still access many of the hand control functions (such as displaying information about the object). NOTE: The Messier, NGC and SAO catalogs require the user to enter a numeric designation. Once you have selected the appropriate catalog button and selected the Messier, NGC or SAO catalog, you will see a flashing cursor indicating you are in numeric entry mode. Enter the catalog number for the object you want to view. Press ENTER to command the telescope to slew to the object, or hold the OPTION button (the Celestron logo) and press OBJECT INFO to see information about the object you selected. CAUTION: Never slew the telescope when someone is looking into the eyepiece. The telescope can move at fast slew speeds and may hit an observer in the eye. Motor Speed Button The MOTOR SPEED button, similar to the Rate button on the original NexStar hand control, 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 control key pad. The number 9 button is the fastest rate (approximately 3.5° per second, depending on the mount) and is used for slewing between objects and locating alignment stars. The number 1 button on the hand control is the slowest rate (half sidereal) and can be used for accurate centering of objects in the eyepiece. To change the speed of the motors: • Press the MOTOR SPEED key on the hand control. The LCD will display the current motor speed. • 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. 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 direction button. This will increase the speed to the maximum slew rate. When using the hand control's up and down direction buttons, 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.
