1. When a desired object is visible in the eyepiece, press MODE until the "Select

Item: Object" menu is displayed.

2. Scroll through the Object menu options until "Object: Identify" displays.

3. Press ENTER to search the database for the identity of the object being observed.

4. If the telescope is not directly on a Starfinder database object, the nearest

database object is located and displayed on the screen. Press GO TO and the

telescope slews to that object.

Event Menu

The Event menu provides access to dates and times of astronomical events. The

Event database includes:

Sunrise and Sunset calculates the time that the Sun rises or sets on the current date.

Find rise and set times for other dates (e.g., a date three months in the past or future)

by entering the new date into the "Setup: Date" menu.

Moonrise and Moonset calculates the time that the Moon rises or sets on the current

date. Find rise and set times for other dates by entering a new date into the "Setup:

Date" menu.

Moon Phases displays the date and time of the next Full, New, 1st Quarter, and 3rd

Quarter Moon.

Meteor Showers provides information on upcoming meteor showers (e.g., the

Perseids, the Leonids, etc.), the dates of the showers, and when they reach maximum.

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, annu-

lar, or partial) of eclipse, and the location and time of the first and last contacts of the

Moon's shadow. Use the Scroll Up and Down keys to display the available data.

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 is 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 sec-

ond star is hidden. Starfinder calculates minimum magnitude time at mid-eclipse.

Autumn and Vernal Equinox calculates the time and date of the fall or spring equinox

of the current year.

Winter and Summer Solstice calculates the time and date of the winter or summer

solstice of the current year.

Glossary Menu

The Glossary menu provides an alphabetical listing of definitions and descriptions for

common astronomical terms and Starfinder functions. Access directly through the

Glossary menu or through hypertext words embedded in Starfinder.

A hypertext word is any word in [brackets], usually found when in the Starfinder Help

function or in a scrolling message such as a description of a planet or star. Press

ENTER whenever a hypertext word is displayed and Starfinder links directly to the

glossary entry for that word.

NEVER point the

telescope directly

at or near the

Sun at any time!

Observing the

Sun or an eclipse

of the Sun, even

for the smallest

fraction of a sec-

ond, will result in

instant and irre-

versible eye dam-

age, as well as

physical damage

to the telescope

itself.
