b. If you have an EQ mount without home positioning
switches, such as the Advanced VX mount, the hand control will
prompt you to manually move the mount to its index marks. To do
this, loosen the clutches and rotate the RA and DEC axes until the
index marks line up. Then retighten the clutches and press ENTER.
c. If you have an AZ mount, point the telescope toward the northern
horizon (i.e. tube positioned horizontally and pointing roughly North)
or southern horizon if you are located in the Southern Hemisphere.
Then, use the SCROLL UP and SCROLL DOWN keys to select
"Auto Align." Press ENTER.
4. If you are using an EQ mount, you will now be asked if you would like to
polar align the mount. We recommend polar aligning before doing sky
alignment, as you will need to perform sky alignment again if you polar
align later. If you would like to polar align at this time, press the ALIGN
button. Otherwise, press ENTER to continue with sky alignment. If you
have chosen to polar align now, refer to the Polar Alignment section
on page 5.
5. Follow the onscreen prompts to input your location, local time,
and date.
- You may want to use the city database to set your location. Don't
worry if your exact location is not in the database. Just select the
nearest city.
6. Select an alignment method. (If you are using an AZ mount, you did
this in Step 3c.) Use the SCROLL UP and SCROLL DOWN keys to
select "Auto Align." Press ENTER.
7. The mount will begin slewing to a position where SSAG will obtain its
fi rst alignment reference. Once the mount stops slewing, SSAG will
capture an image of the sky and determine its position.
NOTE: If the telescope automatically slews to point to an area of the sky
that is locally obstructed (by buildings, trees, etc.), it will fail and
automatically slew to another point to try again.
8. The mount will slew to another position to obtain the second alignment
reference.
9. If you are using an altazimuth mount, the Auto Align process is now
complete. If you are using an equatorial mount, SSAG will slew to
a third position on the other side of the meridian to obtain a third
alignment reference.
10. After SSAG has captured two or three references, you will see "Align
Success!" on the NexStar+ LCD screen.
Your mount is now aligned. However, before it can accurately place
objects in the telescope's fi eld of view, SSAG must determine the offset
between its own fi eld of view and that of the telescope in a process
called "center calibration." If you have never center-calibrated SSAG and
your telescope, the hand control will prompt you to do so immediately
after initial alignment. Refer to the "Center Calibration" section later in
this manual. If you have performed a center calibration previously, the
telescope is now ready to fi nd and place objects near the center of the
fi eld of view.
Manual Align
You may consider using the Manual Align option if you have many
obstructions at your observing location, such as buildings, trees, or power
lines. Manual Align works like Auto Align but allows you to manually slew
the telescope to clear areas of the sky to obtain the alignment references.
Because the telescope won't automatically slew to positions blocked by
obstructions, the overall alignment process is quicker.
To perform a "manual" alignment using the
NexStar+ hand control:
1. Follow steps 1 through 5 in the Auto Align section above.
2. When the hand control prompts you to select an alignment method,
use the SCROLL UP and SCROLL DOWN keys to select "Manual
Align" and press ENTER.
3. The hand control will prompt you to slew the telescope to a clear area
of the sky using the direction buttons. When the telescope is pointing

to a clear area of the sky, press ENTER. SSAG will capture an image
to use as an alignment reference.
NOTE: For best results with EQ mounts, do not slew the telescope
towards the North (or South) poles to capture alignment
references.
4. The hand control will prompt you to manually slew the telescope to
another clear area of the sky.
a. For altazimuth mounts, slew the mount in both axes, making
sure SSAG is pointing at least 60° away from its fi rst alignment
point. Press ENTER. The Manual Align is now complete. Skip to
Step 7.
b. For equatorial mounts, slew the mount to another clear area
of the sky. This location must be on the same side of the meridian
as the fi rst area you chose. Press ENTER.
5. After completing the fi rst two alignment references, the hand control
will display "Add Calib Star?" We strongly recommend adding a third
alignment reference for the best overall pointing accuracy across the sky.
a. Choose "No" to end the alignment with only two references. This
alignment may provide acceptable pointing accuracy in many
cases, especially if Precise GoTo is on (as explained later in this
manual). Skip to Step 7.
b. Choose "Yes" to add a third alignment reference. The telescope
will automatically slew to the other side of the meridian.
6. With the telescope now on the opposite side of the meridian from the
fi rst two alignment points, the hand control will prompt you to choose
a third clear area of sky. Use the direction keys to slew to a clear area
of sky on this side of the meridian and press ENTER.
7. You will see "Align Success!" on the NexStar+ LCD screen when
completed.
Your mount is now aligned. However, before it can accurately place
objects in the telescope's fi eld of view, SSAG must determine the offset
between its own fi eld of view and that of the telescope in a process
called "center calibration." If you have never center-calibrated SSAG and
your telescope, the hand control will prompt you to do so immediately
after initial alignment. Refer to the "Center Calibration" section later in
this manual. If you have performed a center calibration previously, the
telescope is now ready to fi nd and place objects near the center of the
fi eld of view.
User Auto Align
This alignment method only works after you have performed at least one
Manual Auto Align. When you select User Auto Align, the telescope
automatically moves to the alignment points you defi ned during the
previous Manual Auto Align. It's a handy option if you set up in the same
location most nights and there are signifi cant obstructions at the site.
To perform a User Auto Align, follow the instructions for Auto Align above
but choose "User Auto Align" as the alignment method. Once initiated,
the telescope will automatically slew to the fi rst alignment point in the
prior Manual Auto Align. It will then proceed to the other user-defi ned
points to complete the alignment.
Last Align
If you leave your telescope set up in a single location, such as a home
observatory, Last Align is a convenient choice. You can only use this
method if you do not slew or otherwise move the telescope in any way
after powering it off. This alignment method uses the previous SSAG
alignment data stored in the hand control. No further action is required.
Quick Align
This procedure aligns the mount using only the time/date/location
information. It assumes that equatorial mounts are perfectly polar aligned
and altazimuth mounts are level and pointing North. Quick Align does not
use the SSAG device.
