Center and focus the object in the 25mm eyepiece of the telescope. 4 In order to accurately center an object in the eyepiece it may be necessary to change the slew speed of the motors. To change the slew speed, press the RATE button then select a number from 1 (slowest) to 9 (fastest). 5 With the object centered in the eyepiece, use the azimuth (right/left) and altitude (up/down) adjustment knobs on the finderscope to place the red alignment dot directly over the centered object. 6 7 Once you have aligned your finderscope, make sure to turn off the LED light to conserve the battery. Now you are ready to align the telescope. This will have to be done at night. 8 When the display reads NexStar SLT, press ENTER to begin the alignment procedure. Use the UP and DOWN scroll buttons (located on #6 and #9) to select “SkyAlign” then press ENTER. Now you will need to enter your site/time information. 9 10 The hand control will display the last entered time and site information. Since this is your first time using the NexStar, press UNDO to enter your site and time information. Press ENTER to select City Database. Use the Up and Down scroll buttons (located on #6 and #9) and choose the closest city to your present location. Press ENTER after selecting the country, state and city. 11 Using the numeric key pad enter your time information. Press ENTER to continue. Press UNDO to backspace. 12 Hand Control Guide [cont] 16 If the finderscope has been properly aligned, the alignment star should now be visible in the field of view of the eyepiece. 17 The hand control will prompt you to center the bright alignment star in the center of the eyepiece. Once centered, press ALIGN. This will accept the star as your first alignment position. 18 19 Repeat the process for the third alignment star. When the telescope has been aligned to the final star, the display will read “Match Confirmed”. Press UNDO to display the names of the three bright objects you aligned to, or press ENTER to accept these three objects for alignment. 20 Now that your telescope is properly aligned, you are ready to find your first object. Press the TOUR button on the hand control. The hand control will display a list of objects that are visible for the date and location entered. TOUR For the second alignment object, choose a bright star or planet as far from the first alignment object as possible. Once again use the directional arrow buttons to center the object in the finderscope and press ENTER. Once object is centered in the eyepiece, press ALIGN. 15 Use the directional arrow keys on the hand control to slew (move) the telescope towards any bright celestial object in the sky. Center the object in the finderscope and press ENTER. 13 Now, using the Up and Down scroll buttons (located on #6 and #9), verify the time zone you are in and press ENTER. 14 Using the numeric key pad enter the date. Press ENTER to continue. Press UNDO to backspace. 21 Press INFO to read information about the object displayed. Press the DOWN scroll key to display the next object.
