The Hand Control Menu Two Star Align The "Hand Control" menu allows you to customize certain features of the NexStar+ hand control. To access this menu, press the MENU button (#7 on the keypad) and use the scroll buttons to select "Hand Control" and press ENTER. Use the scroll buttons to select from the following options: • Lights Control: Independently adjust the brightness of the number keypad and the LCD. • Scrolling Menu: Adjust how fast words move across the face of the LCD. • Toggle Bold Font: Change the format of the font displayed on the LCD from normal to boldface. • Set Contrast: Use the scroll keys to adjust the contrast of the LCD. • S et Language: Change the displayed language on the LCD. NOTE: The Set Language feature may also appear the first time you use your new hand control. You may also initiate it at any time by holding down the Option button (the Celestron logo) for 10 seconds while powering up the telescope. Alignment Procedures In order for the telescope to accurately point to objects in the sky, it must first be aligned with known positions (stars) in the sky. With this information, the telescope can create a model of the sky, which it uses to locate any object with known coordinates. There are many ways to align your telescope with the sky depending on what information the user is able to provide: • Two Star Align uses the entered time/location information and allows the user to select which two alignment stars the telescope will automatically slew to. • One Star Align uses the same time/location information but only uses one star for alignment. • Solar System Align will display a list of visible daytime objects (planets and the Moon) available to align the telescope. • Quick-Align will ask you to input all the same information as you would for the Two Star Align procedure. However, instead of slewing to the alignment stars for centering and alignment, the telescope bypasses this step and simply models the sky based on the information given. • Last Alignment restores your last saved star alignment and switch position. Last Alignment also serves as a good safeguard in case the telescope should lose power. Two-Star Align allows the user to select two stars on which to align the telescope. To align your telescope using the Two-Star Align method: 1. Select Two-Star Align from the alignment choices given. Based on the date and time information entered, the hand control will automatically select and display a bright star that is above the horizon. • Press ENTER to select this star as your first alignment star. • If for some reason the chosen star is not visible (perhaps behind a tree or building), press BACK to have the hand control automatically select the next brightest star. • Or you can use the Up/Down keys to browse the entire Named Star list and select any one of over two hundred alignment stars. 2. Once the telescope is finished slewing to your first alignment star, the display will ask you to use the arrow buttons to align the selected star with the cross hairs in the center of the finderscope. When centered in the finder, press ENTER. The display will then instruct you to center the star in the field of view of the eyepiece. When the star is entered, press ALIGN to accept this star as your first alignment star. 3. After the first alignment star has been entered, the hand control will automatically select a second alignment star and have you repeat this procedure for that star. When the telescope has been aligned on both stars, the display will ask you if you wish to add additional calibration stars. Calibration stars are used to improve the pointing accuracy of your telescope by compensating for subtle opto-mechanical misalignments between the telescope optics and the mount. Therefore, it is usually a good idea to add at least one additional calibration star to improve the mount's all-sky pointing accuracy. 4. Press ENTER to select a calibration star. Select a star the same way you did with the first two alignment stars and press ENTER. You will notice that all the calibration stars displayed are located on the opposite side of the side of the sky (Meridian) as the original alignment stars. This is essential for an accurate calibration of the mount. Finally, you can choose to continue to add additional calibration stars or Press BACK to complete the alignment. Note: East/West Filtering - In order to ensure the best possible full-sky pointing accuracy, your computerized mount automatically filters and chooses its initial alignment stars so that the first two alignment stars are located on one side of the Meridian and any calibration stars are on the opposite side of the Meridian, as indicated by the "W" or "E" displayed in the upper-right corner of the LCD. East/West filtering can be changed simply by pressing the MENU button at any time during the alignment process. 16 | ENGLISH
