After a successful automatic alignment, StarSense

will display "Alignment Complete . "

FIRST TIME SETUP: CALIBRATE CENTER

The first time you use StarSense AutoAlign,

StarSense needs to know the center of the

telescope's field of view in relation to its camera .

This one-time calibration process takes place

inside the camera and will not require you to

physically adjust the camera or your telescope .

After you complete the calibration, you'll need to

perform the StarSense Auto alignment again .

Before calibrating the center position of your

telescope, a StarSense Auto (as outlined previous-

ly) or StarSense Manual alignment must first be

performed . This allows your telescope to establish

tracking and rough GoTo accuracy .

1. Press STARS . The first option shown is Named

for named stars . Press ENTER to proceed .

2. Choose a named star from the list . For best

results, choose a star that is at least magnitude

2 or less . Look at the bottom of the LCD for

Mag and a value, such as Mag : 1.8 . Use the

SCROLL up/down buttons (also the 6 and 9

keys) to page through the list of named stars .

Press ENTER to slew to the star . You do not

need to know where the star is located . Star-

Sense will slew the telescope to the star for you .

It will be the brightest star in that region of sky .

3. Attach your widest angle/lowest power eyepiece

to the telescope . Look through the eyepiece to

see if the star is there . If you do not see the star

in your eyepiece, proceed to step 4 . If you can

see the star, skip to step 5 .

The hand control is now in coarse centering mode,

which has a rapid slew rate .

4. Using the arrow keys on the hand control,

move the telescope until the star appears in

the eyepiece's field of view . Instead of looking

through the eyepiece, try positioning your eye so

that you create a line of sight down the barrel of

the exterior of the telescope tube . Using this line

of sight, point the telescope roughly at the star,

then make fine adjustments by looking through

the eyepiece . Use the lowest power/widest-angle

eyepiece available .

5. Press ENTER, once the star is in the field of

view of your eyepiece .

The hand control is now in fine centering mode,

which has a slow slew rate .

6. Switch to a higher power eyepiece if available .

Center the star in the field of view . Make the final

centering movements UP and RIGHT . A small

checkmark will appear on the upper right screen

when this is done . (This corrects any errors due

to mechanical backlash in your mount .)

7. Press ALIGN .

StarSense will acquire a new image and note the

offset of the star in the camera . A message will ap-

pear: Solution Found with a new center position

displayed in coordinates on the camera .

8. Press ENTER to accept the new center reference .

From this point forward, StarSense knows where

the center of your telescope's field of view is in

relation to the camera .

Do not move the StarSense camera after the

center reference is established. As long as the

camera does not get bumped, jarred, or rotated,

you can remove the StarSense AutoAlign from

your telescope and reattach it without recalibrating.

After this step is complete, a message will appear

Realignment Required .

You can start a new alignment in the telescope's
