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 cur-

rent date. Find rise and set times for other dates by entering a 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, such as

the Perseids, the Leonids, etc. Also lists 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,

annular, 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. Remember, never use a telescope 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 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 com-

bined 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. The handbox 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 sum-

mer solstice of the current year.

Glossary Menu

The Glossary menu provides an alphabetical listing of definitions and descrip-

tions for common astronomical terms and handbox functions. Access directly

through the Glossary menu or through hypertext words embedded in the hand-

box. A hypertext word is any word in [brackets], usually found when using the

handbox help function or when reading a scrolling message such as a descrip-

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

and the handbox 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 the description.

Utilities Menu

The Utilities menu provides access to several extra features within the handbox,

including a countdown timer and an alarm. The Utilities functions include:

Timer selects a countdown timer. This feature is useful for functions such as

astrophotography and tracking satellites. To use the Timer, press ENTER, then

choose “Set” or “Start/Stop.“

•

Set: Enter the time to be counted down, in hours, minutes, and seconds, then

press ENTER.

• Start/Stop: Activates the timer set previously. Use the Scroll keys to toggle

between ON and OFF. When ON is displayed, press ENTER to activate the

WARNING!

Never use

a tele-

scope to

look at the Sun!

Looking at or near

the Sun will cause

instant and irrevers-

ible damage to your

eye. Eye damage is

often painless, so

there is no warn-

ing to the observer

that damage has

occurred until it

is too late. Do not

point the telescope

or its viewfinder at

or near the Sun. Do

not look through

the telescope or its

viewfinder as it is

moving.

Children

should always have

adult supervision

while observing.
