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 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.

RCX400 specifications

The Meade RCX400 is a highly regarded telescope in the field of amateur astronomy, designed specifically to provide an unparalleled observing experience. Launched by Meade Instruments, this telescope leverages advanced technology to deliver clarity, precision, and ease of use.

At the heart of the RCX400 is its unique Ritchey-Chrétien optical design, which minimizes optical aberrations and provides exceptionally crisp images. This design is favored among professional astronomers and provides users with the ability to capture stunning celestial details. The telescope comes in various aperture sizes, including 10 inch and 12 inch models, allowing users to choose a configuration that best meets their observational needs.

One of the standout features of the Meade RCX400 is its Advanced Coma-Free (ACF) optics. This technology ensures that the telescope produces sharp images across a wide field of view, making it easier to observe extended objects such as nebulae and galaxies. The ACF system includes a specialized corrector plate that eliminates coma, resulting in pinpoint stars even at the edge of the field.

Another significant advancement in the RCX400 is its Autostar II system, which provides a user-friendly interface for navigating the night sky. This computer-controlled system boasts a database of over 145,000 celestial objects, enabling users to locate and track objects with ease. The Autostar II also features a built-in GPS system, allowing for automatic site location and time adjustments, further simplifying the setup process.

The RCX400 is equipped with an innovative focusing mechanism known as the “Smart Focuser.” This precise focusing system allows for fine-tuning of the telescope's focus electronically, eliminating the need for manual adjustments that could result in misalignment. Users can achieve optimal focus effortlessly, enhancing the overall observation experience.

In terms of construction, the telescope features a sturdy aluminum mount that provides stability during use. The integrated GoTo mount makes aligning the telescope simple, allowing users to easily point towards celestial objects with high accuracy. The RCX400 is also compatible with various accessories such as cameras and eyepieces, enhancing its versatility for astrophotography and visual observation.

Overall, the Meade RCX400 combines cutting-edge technology with robust features, making it an excellent choice for both novice and experienced astronomers. Its user-friendly design, combined with high-quality optics, ensures that users can enjoy impressive views of the universe with relative ease. Whether for visual exploration or astrophotography, the RCX400 stands out as a formidable tool for stargazing enthusiasts.
