Cord Wrap, when set to "On," moves the telescope in such a way as to prevent the cords and
cables attached to your telescope assembly from getting wound around the assembly and tan-
gled as the telescope slews to objects. "Off" is the default setting.

Manual Alignment Menus: The telescope must be initialized and aligned before Autostar can
find stars in the sky. If you wish to align the telescope manually, you may do by choosing Easy
Two Star Align, Two Star Align or One Star Align from the Set up menu. Otherwise Autostar per-
forms the default alignment, Automatic Alignment. See page 18.
Unlike the Automatic Alignment procedure, the observer must set the telescope into the home
position before choosing one of the manual alignment methods:

Two-Star Alignment requires some knowledge of the night sky. Autostar displays a database
of bright stars and two stars are chosen by the observer from the database for alignment. It is

Position (Fig. 16). Because the Two-Star Alignment methods use two stars to align upon, they
are more precise than One-Star Alignment.
Date changes the date used by Autostar. This function is useful to check events in the past or
future. For example, set the Date menu for a day three months in the future. Then check the
"Select Item: Event" menu for the Sunset time on that date. See

Tighten the Altitude lock (Fig. 17) to a firm feel only.
Point the telescope North. Use a compass or the North Star, Polaris as a guide to locating
North. See Fig. 31, page 35. Also, See Fig. 22.

Model: Allows you to select the telescope model connected to Autostar.
Focal Length: Displays the focal length of the selected telescope.
Az Ratio and Alt Ratio: The Az (Azimuth) ratio and Alt (Altitude) ratio refers to the gears
of the telescope's motors. Do not alter these numbers.
Az Percent: The Az (Azimuth) Percent allows you to change the azimuth backlash, i.e., the
way the Arrow keys move the telescope along the azimuth (horizontal) axis. If you enter a
value near 100, the telescope tube responds more quickly (it responds immediately at
100%) as you hold down an Arrow key and also slews (moves) the tube more quickly. If
you enter a value near 0, it takes longer for the tube to respond as you hold down an Arrow
key and also slews the tube more slowly. Experiment with this option. Try changing the per-
cent value until you get a "feel" for the Arrow keys that is comfortable for you.
Alt Percent: The Alt (Altitude) Percent operates identical to the AZ Percent option (see
above), but allows you to change the altitude backlash, i.e., the way the Arrow keys move
the telescope when moving along the altitude (vertical) axis.
