Event Menu

The Ev

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

base 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 by entering a new date into the “Setup: Date” menu. See

DATE, page 11.

Moonrise and Moonset calculates the time that the Moon r

ises or sets on the current date.

Find r

ise and set times for other dates by entering a new date into the “Setup: Date” menu. See

DATE, page 11.

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, such as the Perseids, the

Leonids,

etc. Also lists the dates of the showers and when they reach maximum.

NOTE: Meteor showers 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 par-

tial) 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. Remember, never use a tele-

scope to look at the Sun! See “WARNING!” to the left.

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 sys-

tem, 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 pass-

es behind the other. The combined magnitude of the two stars thus dips from +2.1 to a mini-

mum of +3.4 halfway through the eclipse as the second star is hidden. AutoStar calculates min-

imum 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 AutoStar functions. Access directly through the Glossary menu or

through hypertext words embedded in AutoStar. A

hypertext word is any word in [brackets],

usually found when using the AutoStar Help function or when reading a scrolling message such

as a descr

iption of a planet or star. Press ENTER whenever a hypertext word is on screen and

AutoStar goes to the glossary entry for that word.

To access directly from the Glossary menu, use the Scroll keys to scroll through the alphabet.

Press ENTER on the desired letter

. Scroll to the desired entry and then press ENTER to read

WARNING!

Never use a

Meade

Telescope to look at

the Sun! Looking at

or near the Sun will

cause instant and

irreversible damage

to your eye. Eye

damage is often

painless, so there is

no warning to the

observer that dam-

age has occurred

until it is too late. Do

not point the tele-

scope or its viewfind-

er at or near the Sun.

Do not look through

the telescope or its

vie

wfinder as it is

moving.

Children

should always have

adult super

vision

while obser

ving.
