andyou are now ready to find your first object .
If the wrong star was centered and aligned to, the NexStar display will read Align Failed
Align FailedAlign Failed
Align Failed.Press UNDO to begin the
alignment procedure again.
If youa renot sure if the correct star was centered, always remember that the alignment starwill be the brightest
starnearest the field of view of the finder. There may be other fainter stars visible that are closer to the center of the
StarPointer, but the actual alignment star will be obviously brighterthan any other star in the area.
Forthe best possible pointing accuracy, always center the alignment stars using the up arrow button and the right
arrow button. Approaching the star from this direction when looking through the eyepiece will eliminate much of the
backlash between the gears and assure the most accurate alignment possible.
Two Star Alignment
Withthe two-star alignment method, the NexStar requires the user to know the positionsof only two bright stars in order to
accurately align the telescope with the sky and begin finding objects. Here is an overview of the two-star alignment
procedure:
1. Once the NexStar is powered on, use the Up and Down scroll keys to select Two

ENTER.
2. The NexStar display will ask you tomove the telescope tube until it is horizontal to the ground. To do this, use
thedirection keys (3) to move the telescope until it is roughly level with the ground. Press ENTER.
3. The SELECT STAR 1
SELECT STAR 1SELECT STAR 1
SELECT STAR 1 messagewill appear in the top row of the display. Use the Up and Down scroll keys (10) to
selectthe star you wish to use for the first alignment star. Press ENTER.
4. NexStar then asks you to center in the eyepiecethe alignment star you selected. Use the direction buttons to slew
thetel escope to the alignment star and carefully center the star in the eyepiece.
5. Once the alignment star is centered in the field of view of the eyepiece, press the ALIGN key (2) to accept this
position.
6. NexStar will then ask you to select and center a second ali gnment star and press the ALIGN key. It is best to
choosealignment stars that are a good distance away fromone another. Stars that are at least40º to 60º apart from
eachot her will give you a more accurate alignment than stars that are close to each other.
Once the second star alignment is completed properly, the display will read Alignment Successful
Alignment SuccessfulAlignment Successful
Alignment Successful, and youwill hear the
tracking motors turn-on and begin to track.
Quick-Align
Quick-Align allowsyou to input all the same information as you would for the AutoAlign procedure. However, instead of
slewingto two alignment stars for centering and alignment, the NexStar bypasses this step and simply models the sky based
on theinformation given. This will allow you to roughlyslew to the coordinates of bright objects like the moon andplanets
and gives the NexStar the information needed to track objects in altazimuth in any part of the sky. Quick-Align is not meant
to be used to accurately locate small or faint deep-sky objects or to track objects accurately for photography. Note: Once a
Quick-Align has been done, you can use the Re-alignment feature(see below) to improve your telescopes pointing and
tracking accuracy.
Touse Quick-Align:
1. Select Quick-Align from the alignment options.
2. Use the arrow buttons to level the tube and positionthe telescope tube towards north and press ENTER.
3. The hand control will then ask you to input all the same time and location information asyou would for the
AutoAlignprocedure.
Onceentered, the NexStar will model the sky based on this information and display Alignment Successful
