Smart Mount: See page 69 for detailed information.

GPS-UTC Offset: Univ

ersal Time (UTC) adds leap seconds to its time calculations,

GPS does not. The offset is the number of leap seconds added since the establish-

ment of GPS

Telescope: Accesses several options, including:

J Mount: Set this option to "Alt/Az" if using alt/az alignment and to "Polar" if using

polar alignment. "Alt/Az" is the default value.

J Model: Allows you to select the telescope model connected to Autostar II.

J Focal Length: Displays the focal length of the selected telescope.

J Max Slew Rate: Sets the upper limit for the slew rate. 8 degrees per second is

the fastest setting.

J Focuser: Allows you to recalibrate your focuser. Normally, not used. Recalibrates

focuser and focuser backlash.

J Collimate: Allows you use the Arrow keys to collimate the telescope. See pages

51 and 52 for more details.

J Mount Upper Limit: Allows you enter a number from 0 to 90 that sets an upper

limit as to how far the optical tube can swing upward during a programmed slew.

(Note that it does not prevent you from performing a manual slew past this limit.)

This is useful when you have a camera or other peripheral attached to the tele-

scope—you can prevent it from striking the telescope base. 90 (straight up) is the

maximum value that can be entered.

J Mount Lower Limit: Allows you enter a number from 0 to 90 that sets a lower

limit as to how far the optical tube can swing downward during a programmed

slew. (Note that it does not prevent you from performing a manual slew past this

limit.) This is useful when you have a large optical tube (12" model) or have a

dewshield attached to the telescope—you can prevent it from striking the tele-

scope base. -90 (straight down) is the maximum value that can be entered.

J Park Position: For permanently mounted telescopes only. After aligning your tel-

escope, select this menu and power down the telescope. The alignment set-

tings—level, 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 tele-

scope, "Automatic Alignment" displays after the start up routine. Press MODE (do

not press ENTER). The telescope remembers its alignment and you can contin-

ue 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. Use Default Position levels telescope and points it North.

J Calibrate Home: For permanently mounted telescopes only. After aligning your

telescope, select this menu and the alignment settings—level, North, time, align-

ment 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 choos-

ing the Align on Home menu. See

ALIGN ON HOME, page 32, for more informa-

tion.

Note: This method is not as precise as PARK POSITION (see above).

J 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.

J Train Drive: All telescopes have a certain amount of "backlash" (looseness in the

inter

pla

y of gears).

This menu allows you to compensate for the backlash in the

the Altitude and Azimuth motors—which helps locate objects with more precision.
