Meade MAX-ACF instruction manual Event Menu, Glossary Menu, Utilities Menu

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 param- eters 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 tran- sit, or Moon set on the current date. Find rise and set times for other dates by enter- ing 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. Use the Scroll Up and Down keys to display the avail- able data. This option is dependent on your location.

Lunar Eclipse: Lists upcoming Lunar Eclipses, including the date and type (total, par- tial, 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

2.8days during a 10-hour period, Algol undergoes a major change in apparent mag- nitude 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 date of the fall or spring equi- nox of the current year.

Winter and Summer Solstice: Calculate 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 II functions. Access directly through the Glossary menu or through hypertext words embedded in Autostar II. A hypertext word is any word in [brackets], usually found when using the Autostar II Help function or when reading a scrolling message such as a description of a planet or star. Press ENTER whenever a hypertext word is on screen and Autostar II goes to the glossary entry for that word.

To access directly from within 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 Autostar II, includ-
	ing a countdown timer and an alarm. The Utilities functions include:
	Balance OTA: Use while you're balancing the OTA (see pages 22 - 23 for complete
36	procedure). Allows to balance on both axes.
	Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the
	Sun. Do not look through the telescope as it is moving.
