telescope by adding multiple calibration references .

You can have up to 10 alignment reference points

to improve GoTo accuracy . This feature is especially

useful for astroimaging, to better center objects in

the imaging sensor .

StarSense Auto starts Alt-Az mounted telescopes

with 3 align reference points . Equatorial mounted

telescopes start with 4 align reference points .

Depending on your mount type, you can add either

6 or 7 additional alignment references to improve

pointing accuracy if desired .

1. Press ALIGN and scroll UP/DOWN until Add

Align Ref is displayed and press ENTER .

2. Using the arrow keys, move the telescope several

degrees away from its last alignment point .

Remember to finish movement with the UP

and RIGHT direction buttons . A checkmark will

appear on the display to confirm this .

If you only intend to add one additional align reference

point, then position the telescope in the area you

are going to observe or image in .

3. Press ENTER and StarSense will acquire a

new image and add the align reference point

for a total of 10 reference points .

You can repeat this process up to 9 additional

times in different regions of the sky . Adding align

refrence points improves the GoTo mount modeling,

which accounts for flexure and other mechanical

inaccuracies to provide the best possible

pointing accuracy .

SOLAR SYSTEM ALIGN

Solar System Align provides good tracking and

GoTo performance by using solar system objects

(the Sun, Moon and planets) to align the telescope

with the sky . Solar System Align is a great way to

align your telescope for daytime viewing as well as

a quick way to align the telescope for night time

observing . Since the StarSense camera cannot

detect celestial objects during the day, Solar System

Align is done using the eyepiece .

WARNING

• Place cap over the camera lens! Since you may

wish to use the Sun for your alignment, remember

to place the cap over the camera lens to protect

the imaging sensor .

• Never look directly at the Sun with the naked eye

or with a telescope (unless you have the proper

solar filter) . Permanent and irreversible eye damage

may occur .

1. Press the ALIGN button .

2. Use the UP/DOWN scroll keys to select Solar

System Align from the alignment options and

press ENTER .

3. Move the telescope to its home position or

switch position . Alt-Az mounts should have the

telescope pointing at the horizon . Equatorial

mounts should be positioned to the index marks .

Telescopes with switch postions will automatically

move to the home switch positions .

4. Use the UP/DOWN scroll keys to select the

Solar System object you wish to align and

press ENTER .

The hand control will only display the solar system

objects that are above the horizon for the day and

time selected .

5. Following the prompts on the hand control, center

the object in your eyepiece . Use the direction

arrow buttons to slew the telescope to the

alignment object . A finderscope or Star Pointer

will help locate the object .

6. Press ENTER when the object is in the

eyepiece's field of view . Then, center the

object in the eyepiece and press ALIGN .

Once in position, StarSense will model the sky

based on this information and display Alignment

Complete .
