User manual CELESTRON NEXSTAR 8SE Instruction Manual

[. . . ] The NexStar ushers in a whole new generation of computer automated technology. Simple and friendly to use, the NexStar is up and running after locating just three bright objects. If you are new to astronomy, you may wish to start off by using the NexStar's built-in Sky Tour feature, which commands the NexStar to find the most interesting objects in the sky and automatically slews to each one. Or if you are an experienced amateur, you will appreciate the comprehensive database of over 40, 000 objects, including customized lists of all the best deep-sky objects, bright double stars and variable stars. [. . . ] Get Axis Position - Displays the relative altitude and azimuth for the current position of the telescope. 22 Goto Axis Position - Allows you to enter a specific altitude and azimuth position and slew to it. Hibernate - Hibernate allows the NexStar to be completely powered down and still retain its alignment when turned back on. This not only saves power, but is ideal for those that have their telescopes permanently mounted or leave their telescope in one location for long periods of time. Remember to never move your telescope manually while in Hibernate mode. After pressing Enter you have the option of scrolling through the time/site information to confirm the current setting. Helpful Hint Sun Menu For safety purposes the Sun will not be displayed as a database object unless it is first enabled. The Sun will now be displayed in the Planets catalog as can be used as an alignment object when using the Solar System Alignment method. To remove the Sun from displaying on the hand control, once again select the Sun Menu from the Utilities Menu and press ENTER. Scrolling Menu This menus allows you to change the rate of speed that the text scrolls across the hand control display. · Press the Up (number 6) button to increase the speed of the text. · Press the Down (number 9) button to decrease the speed of the text. Calibrate Goto Goto Calibration is a useful tool when attaching heavy visual or photographic accessories to the telescope. Goto Calibration calculates the amount of distance and time it takes for the mount to complete its final slow goto when slewing to an object. Changing the balance of the telescope can prolong the time it takes to complete the final slew. Goto Calibration takes into account any slight imbalances and changes the final goto distance to compensate. Set Mount Position The Set Mount Position menu can be used to recover an alignment in cases where the telescope or tripod has been manually moved. For instance, you might use this feature if you needed to adjust the level of the tripod by raising or lowering the tripod legs. After the mount has been moved, simply slew to a bright star and center it up in the eyepiece, then select Set Mount Position from the Utilities menu. Since the telescope has been moved, the pointing accuracy will be diminished. But now you can slew to a new set of alignment stars and replace any of the original alignment stars with the new stars. This will help you to avoid having to start the alignment process over from the beginning. Wedge Align ­ The NexStar has two equatorial alignment modes (one for the northern hemisphere and one for the southern) that will help you to polar align your telescope when using an optional equatorial wedge.
