Press GO TO. The telescope, if aligned, will slew to
that chosen object. Press MODE repeatedly to return
to previous menu levels.
User Objects:
not currently in the Autostar II libraries. See CREATING
USER OBJECTS, page 37, for more information.
Identify:
telescope has been properly aligned, use the Autostar II
Arrow keys to move about in the sky. Then follow
this procedure:
Important Note: Only use the Arrow keys to
move the telescope during the Identify procedure.
Do not loosen the telescope locks or move the
base or alignment is lost.
1. When a desired object is visible in the eyepiece,
keep pressing MODE until the "Select Item:
Object" menu is displayed. Press ENTER to select
this menu.
2. Scroll through the Object menu options until the
"Object: Identify" screen appears.
3. Press ENTER. Autostar II searches the libraries for
the identity of the object being observed.
4. If the telescope is not directly on an Autostar II
library object, the nearest library object is located
and displayed on the screen. Press GO TO and the
telescope slews to that object.
Browse: Allows you to search the library for objects
with certain parameters, much like a search engine.
"Edit Parameters" lets you set various parameters for
the search, such as: Object Type, Minimum Elevation,
Largest, etc. Once you have set the parameters of
the search, select "Start Search" and press ENTER.
Autostar II will display the results of the search.

Event Menu

The Event menu provides access to dates and times
of astronomical events. The Event database includes:
Sunrise, Sun Transit, and Sunset: Calculate the time
of Sun rise, Sun transit, or Sun set on the current date.
Find rise and set times for other dates by entering a
new date into the "Setup: Date" menu.
Moonrise, Moon Transit, and Moonset: Calculate
the time of Moon rise, Moon transit, or Moon set on the
current date. Find rise and set times for other dates by
entering a new date into the "Setup: Date" menu.
Moon Phases:
Full, New, 1st Quarter, and 3rd Quarter Moon.
Meteor Showers: Provides information on upcoming
meteor showers, such as the Perseids, the Leonids,
etc. Also lists the dates of the showers and when they
Note: Meteors are fast moving objects that cover
large areas of the sky and are usually best observed
with the naked eye.
Solar Eclipse: Lists upcoming Solar Eclipses,
including the date and type (total, annular, or partial)
of eclipse. Use the Scroll Up and Down keys to display
the available data. This option is dependent on your
location.
Lunar Eclipse: Lists upcoming Lunar Eclipses,
including the date and type (total, partial, penumbral)
of eclipse. Use the Scroll Up and Down keys to display
the available data.
Min. (Minimum) of Algol: Displays the minimum
brightness of the dramatic eclipsing binary star system,
Algol. It is relatively close at a distance of 100 light
years. Every 2.8 days during a 10-hour period, Algol
undergoes a major change in apparent magnitude
as one of the two stars passes behind the other. The
combined magnitude of the two stars thus dips from
+2.1 to a minimum of +3.4 halfway through the eclipse
as the second star is hidden. Autostar II calculates
minimum magnitude time at mid-eclipse.
Autumn and Vernal Equinox: Calculate the time and
Winter and Summer Solstice: Calculate the time
and date of the winter or summer solstice of the
current year.
