NSuggest: AutoStar calculates and suggests the best eyepiece for viewing, based on the telescope and the object being viewed.

Display Options enables or disables AutoStar’s two initial displays. If both displays are dis- abled, AutoStar begins with the Date display.

NSun Warning: Turns the “Sun Warning” message on or off.

NGetting Started: Turns the “Getting Started” message on or off.

Park Scope is designed for a telescope that is not moved between observing sessions. Align the telescope one time, then use this function to park the telescope. Next time it is powered up, enter the correct date and time – no alignment is required. Pressing ENTER causes the tele- scope to move to its pre-determined Park position. Once parked, the screen prompts to turn off power.

IMPORTANT NOTE: When the "Park Scope" option is chosen and the display prompts you to turn off the telescope's power, AutoStar is unable to be returned to operation without turning the power off and then back on.

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.

Setup Menu

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, Easy Alignment.

To Set the Home Position for manual alignment methods::

1.Loosen the telescope’s Altitude lock.

2.Level the optical tube: Line up 0° on the Altitude setting circle with the molded triangular pointer next to the circle.

3.Tighten the Altitude lock (Fig. 17) to a firm feel only.
