Celestron CGX Equatorial 800 HD Telescopes CGX EQ Mount and Tripod Manual - Page 18

Object Catalog 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. 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. • Solar System - The Solar System catalog will display all the planets (and Moon) in our Solar System that are currently visible in the sky. To allow the Sun to be displayed as a selectable object in the database, see the Sun Menu option in Scope Setup Menu. • Stars - The Stars catalog displays custom lists of all the brightest stars, double (Binary) stars, variable stars, constellations and selected asterisms. SkyTour Button The CGX mount includes a tour feature which allows you 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 catalog filters limits. To activate the Tour feature, press the SKY TOUR key on the hand control. 1. Press the SKY TOUR button on the hand control. • Deep Sky - The Deep Sky catalog displays a list of all 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 want 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 rapidly. Slewing to an Object Once the desired object is displayed on the hand control screen, you have two options: 2. Use the SCROLL buttons to select Best of Tonight. 3. The CGX mount will automatically slew in azimuth to its starting position which will help minimize the chance of wrapping the power cord during the tour. 4. 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 OBJECT INFO key. Press it once to display the coordinates of the object. Press it again to display the coordinates of the object. Press it again to display the text description. Press BACK to return to the previous screen. • To slew to the object displayed, press ENTER. • To see the next tour object, press the DOWN key. • 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 Identify Button Pressing the IDENTIFY button will search the mount's database catalogs and display the name and angular distances to the nearest matching objects from the telescope's current location. This feature can serve two purposes. First, it can be used to identify an unknown object in the field of view of your eyepiece. Additionally, Identify Mode can be used to find other celestial objects that are close to the objects you are currently observing. For example, if your telescope is pointed at the brightest star in the constellation Lyra, choosing Identify will no doubt return the star Vega as the star you are observing. However, the Identify feature will also search its NGC and Solar System databases and display any planets or Deep Sky objects that are close by. In this example, the Ring Nebula (M57) would display as being approximately 6° away. The brightness and proximity of the objects displayed can be defined by the user using the Identify Filter under Telescope Setup. 18 | ENGLISH
