prompts you to turn off the telescope's power, Autostar II is unable to be
returned to operation without turning the power off and then back on.
Setup Menu
There are numerous other features available within the Setup menu, including:
Align:
Let's you choose a method of alignment.
Align on Home:
If Calibrate Home has been performed, power up your telescope and
select this menu to return the previously calibrated home position. In other words, the
telescope is fully aligned according to the setting that were stored in Autostar II's
memory during the Calibrate Home procedure. See
CALIBRATE HOME
, below, for
more information.
Telescope:
Accesses several options, including:
쩦
Telescope Model:
Allows you to select the type of OTA mounted on Max.
쩦
Collimate:
Allows you use the Arrow keys to collimate the telescope. See pages
28 - 29 for more details.
쩦
Align OTA:
Allows you to align the OTA properly if you are not using an MAX-
ACF model or if you have changed your MAX-ACF collimation or mounting sig-
nificantly from the factory defaults. When you select this menu, Autostar will ask
you to center two stars in the telescope that are on opposite sides of the sky.
Once you have centered them, the telescope will slew back to the first star. You
will then be asked to center the star using the OTA align bolt. See page 30 for
more information.
쩦
Max Past Meridian
: Allows you to set how far the OTA axis can tilt past the
meridian. 2° is the default setting.
쩦
Focal Length:
Displays the focal length of the selected telescope.
쩦
Max Slew Rate:
Sets the upper limit for the slew rate. 2.4° degrees per second is
the fastest setting.
쩦
Park Position:
After aligning your telescope, select this menu and power down
the telescope. The alignment settings—North, time, alignment stars—are stored
in Autostar II's memory and are remembered after you power off the telescope.
When you power on the telescope, "Automatic Alignment" displays after the start
up routine. Press MODE (do not press ENTER). The telescope remembers its
alignment and you can continue viewing or performing other operations without
aligning the telescope again.
Park Position provides two options. Use Current Position uses the last position set
by the user. Default Position places scope in the home position.
쩦
Calibrate Home:
For permanently mounted telescopes only. After aligning your
telescope, select this menu and the alignment settings—North, time, alignment
stars—are stored in Autostar II's memory and are remembered after you power
off the telescope. You can enable Autostar II to retrieve and automatically align
your telescope using these settings the next time you power up by choosing the
Align on Home menu. This menu helps improve auto alignment.
쩦
Anti-Backlash:
This option allows you to change the backlash along either the
R.A. and the Dec. axes by entering a number from 0% to 199%. This sets the back-
lash in the way the Arrow keys move the telescope along an axis. If you enter a
value near 199%, telescope responds more quickly as you hold down an Arrow
key. If you enter a value near 0%, it takes longer for the tube to respond as you
hold down an Arrow key. Experiment with this option: Try changing the values until
the motion of the telescope (while holding down an Arrow key) feels comfortable
to you.
쩦
Train Drive
: All telescopes have a certain amount of "backlash" (looseness in the
interplay of gears). This menu allows you to compensate for the backlash in the
the R.A. and Dec motors—which helps locate objects with more precision.
쩦
Tracking Rate:
Changes the speed at which the telescope tracks targets
Looking at or near the
Sun
will cause
irreversible
damage to your eye. Do not point this telescope at or near the
Sun. Do not look through the telescope as it is moving.
