Meade Instruments LX850 - Manual (Page 43)

Easy Polar Alignment
Easy Alignment is similar to Two-Star Polar Alignment,
except it requires no knowledge of the night sky.
Autostar II, rather than the user, chooses two stars
its library and merely asks the user to center them in
the eyepiece.
To Download the Latest Version of
Autostar II Software
Included with your telescope is a DVD ROM and a
USB cable. You need to install the USB drivers, that

screen instructions.
4. Once the Autostar Suite software installs, double-
click the new “Autostar Suite” icon on the desktop.

Autostar.” The “Autostar Update” screen
displays. Click the “Upgrade Autostar Software

6. The application detects your telescope type and
the version of Autostar software on your handbox.
7. A window displays asking if you wish to download
the latest version of Autostar from your hard drive
(if you previously downloaded it separately from the
Meade website) or from the Internet. Select one of
the choices and follow the on-screen instructions.
8. The download will take about 10 minutes (download
time depends on your Internet connection, speed of
your computer and so forth). When the download
is complete, the new version of the Autostar

Starlock Assisted PEC Training
Periodic Error Correction (PEC) helps to remove the
slight perturbations in tracking that occur due to the
mechanical nature of a telescope. Follow the steps
below to perform this procedure using StarLock:
1. Point the telescope’s OTA at a moderately bright
star near 0 declination (celestial equator).
2. Wait for the StarLock indicator lamp to stop
blinking and become solid red, which indicates
that it has located and locked onto the guide star.
3. Using your AutoStar handbox, navigate to the
“Setup: Telescope” menu. Press ENTER.
4. Scroll through the options until “Telescope: RA
PEC” displays. Press ENTER.
5. Scroll through the options until “RA PEC: Train”
displays. Press ENTER.
6. Scroll through the options until “RA PEC: Update”
displays. Press ENTER.
7. Repeat step 6 one more time to improve the
PEC training.
Update Menu Option
Use the Update option to further refine your training; it
is recommended that you update your original training
two or three times when first using your telescope.
Update does not overwrite the data, but updates the
training using information gathered from both the last
and the current training sessions. Press the MODE
key to exit from this option. If you wish to further
refine your training, select this menu again and repeat
the procedure.
Erase Menu Option
Select this option to erase all PEC training data.
On and Off Menu Options
Select “On” when you want the telescope to use the
training information. Select “Off” when you do not want
for the telescope to use the training information. Select
“On” to enable the Smart Drive.
