I ENGLISH
For the telescope to accurately point to objects in the sky, it must first be aligned with known positions (stars) 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:
• SkyAlign works by aligning on any three bright stars or planets in the sky
• One Star Align uses the entered time/location information and allows the user to select one alignment star Provides a
fast alignment, at the expense of less pointing accuracy
• 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
• Auto Two Star Align will display a list of visible daytime objects (planets and the Moon) available to align the telescope
• 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 loses power
• EQ North / EQ South Alignment is used when polar aligned on an optional equatorial wedge Similar to the altazimuth
alignments described earlier, the EQ alignments gives you the choice of performing an AutoAlign, Two-Star alignment,
One-Star alignment or Solar System alignment
OVERVIEW OF TWO POPULAR ALIGNMENT METHODS
ALIGNMENT PROCEDURES
1 Flip the NexStar Evolution’s power switch on The hand control will display “Verifying Packages…” After a few seconds,
it will display “Evolution ” Press ENTER to choose SkyAlign or use the UP/DOWN scroll keys (10) to select a different
method of alignment
2 Press ENTER You will be prompted to enter the local time in 24-hour format Ex 21:00 for 9PM
3 Select Daylight Savings or Standard Time, toggle the 6 & 9 (up and down scrolling keys) to change
4 Select time zone, then enter the date
5 Press ENTER to begin SkyAlign Use the arrow buttons on the hand control to slew (move) the telescope towards any
bright celestial object in the sky Center the object in the crosshairs of the finderscope and press ENTER
6 If the finderscope has been properly aligned with the telescope tube, the alignment star should now be visible inside the
field of view of the eyepiece Center the star in the eyepiece using the direction keys on the hand controller and press the
ALIGN button This will accept the star as the first alignment position (There is no need to adjust the slewing rate of the
motors after each alignment step The NexStar automatically selects the best slewing rate for aligning objects in both the
finderscope and the eyepiece)
7 For the second alignment object, choose a bright star or planet as far as possible from the first alignment object Once again,
use the direction keys to center the object in the finderscope and press ENTER Center the object in the eyepiece, then
press the ALIGN button
8 Repeat the process for the third alignment star When the telescope has been aligned to the final stars, the display will read
“Align Success ”
