to start up the system.
4. “Press 0 to Align or Mode for Menu” displays. Press 0 to align your telescope using the
“Easy Align” method, see “Easy (Two-Star) Align” on page 19. To skip the alignment
process and access the AutoStar menus, press the Mode key.
5. The telescope then tests the motor function of the telescope by moving in the horizontal
and vertical directions.
6. The next screen requests the status of Daylight Savings Time. If Daylight Savings Time is
active, press the “1” key. If Daylight Savings Time is not active, press the “2” key.
Note : Daylight Savings Time may be referred to by a different name in various areas of the
world.
7. AutoStar then asks for the Telescope Model. Using the scroll keys (Pg. 10, Fig. 2, 7) on the
AutoStar locate the model of your telescope and press enter.
8. System initialization is complete and the screen reads “Setup: Align”
Easy (Two-Star) Align
The fastest and easiest way to locate objects with Autostar's GO TO capabilities is to use Easy
Align.
Autostar automatically picks two stars from its database for the Easy Align procedure. During
this procedure, Autostar slews the telescope to a first alignment star. The user is asked to verify
that the telescope is pointed at the chosen star and then prompted to center the star in the
eyepiece. The process is repeated with a second star to complete the alignment.
NOTE: Before aligning the telescope, first verify that “INITIALIZING AUTOSTAR”,
page 18, has been performed. See “MOVING THROUGH AUTOSTAR’S MENUS”,
page 18, for a description of how Autostar’s keys operate.
How to perform the Easy Align Procedure
If you have just applied power to Autostar, perform steps 1 through 5. If you have just performed
the initialization procedure, go to step 6.
1. Turn the telescope on: Turn the telescope power switch to the ON position. The AutoStar
beeps and the display screen is activated. AutoStar then takes a few moments to start up
the system.
2. Select Alignment Procedure: “Press 0 to Align or Mode for Menu” displays. Press 0 to
begin Easy (Two-Star) Alignment. To skip the alignment process and access the AutoStar
menus, press the Mode key.
Note: AutoStar initializes the Smart Drive if turned “On”, the user has previously performed
PEC training, and you have “parked” the telescope. If you have parked it, Autostar will
remember its position on the worm gear. If you do not park the scope and turn it off, it will
not remember its position. See PARK, page 28 and PEC TRAINING, page 53.
3. Testing Motors: The telescope then tests the motor function of the telescope by moving
in the horizontal and vertical directions.
4. Daylight Savings Time: The next screen requests the status of Daylight Savings Time. If
Daylight Savings Time is active, press the 1 key. If Daylight Savings Time is not active,
press the 2 key.
Note: Daylight Savings Time may be referred to by a different name in various areas of the
world.
5. Telescope Model: AutoStar then asks for the Telescope Model. Using the scroll keys (Pg.
10, Fig. 2, 7) on the AutoStar locate the model of your telescope and press enter.
6. Setting the Home Position: “North Method: 1=True 2=Compass” displays. AutoStar is
asking which Home Position method to use to setup the telescope. See page 18 “Setting
the “Alt/Az” Home Position using Magnetic North” or Setting the “Alt/Az” Home
Position using True North. The easiest way to set the telescope in the home position is
using the Magnetic North method. Follow the steps on page 18 to set the home position.
If using True North, press the “1” key, or press the “2” key to use Magnetic North.
7. With the telescope in the home position, press the “Enter” key.
8. Attempts a “GPS Fix”: The GPS receiver attempts to acquire and sync up with signals
from GPS satellite system. “Getting GPS Fix” displays. See THE GLOBAL POSITIONING
SYSTEM on page 21.
After performing these operations, AutoStar now knows the
IMPORTANT NOTE:
While performing the
automatic tracking,
only use the Arrow
keys to move the
telescope. Once the
telescope has been
set in the Alt/Az home
position, do not loosen
the telescope locks
(
Fig. 1, 6 and 9 ), or
move the base
manually, or alignment
will be lost.
Important Tip:
It is recommended
that you train your
telescope’s drive the
first time you align
your telescope.
Training the drive
improves your
telescope’s pointing
precision.
For more information
about training the
drive, see page 55 for
more information.
IMPORTANT NOTE:
The “Telescope: Mount”
option of the Setup menu
is set to “Alt/Az” as the
default alignment by the
factory.The example
presented in this section
assumes that you are
performing an alignment
procedure for the first
time with your telescope
and therefore, the
“Telescope: Mount”
option does not need to
be selected. For
information on equatorial
(Polar) alignment, see
APPENDIX A
