"Hot Button" Menus

Two menus, six object libraries and two functions can be accessed directly using the Number keys (commonly referred to as "hot buttons"). The two functions, the Speed mode and the Utility light are described earlier in the manual.

Focus Control Menus: Press Number key "4" to select these menus directly from Autostar II's keypad. Each time you press Focus, the key toggles between focus/focus speed menus and the preset control menus. When “Focuser: Fast” displays, press the Up or Down Scroll keys to select a focus speed (fast, medium, slow or fine). When “Focuser: Position” displays, use the Up or Down Arrow keys to achieve fine focus of the object.

You can toggle the Focus key to display the “Focuser: Preset” menus. The Focuser pre- set menu allows you to assign nine focus positions. If you “park” the telescope, you can set your own focus, focus for your observing partners and the focus for your camera or imager. Other Preset menus allow you to select a focus you have assigned and also to Sync on a Focus Preset. The Sync on a Focus Preset allows you retrieve focus posi- tions when you do not park your telescope. See page 20 for more information. Also see page 32 for information about parking your telescope.

Reticle Control Menu: Press Number key "7" to select this menu directly from

Autostar II's keypad. "Reticle Control: Set Intensity" displays. Press ENTER. The Intensity menu allows you to change the intensity of the Reticle Eyepiece Illuminator. Use the Scroll keys to change the value. As you change the value, look through the reticle to note how the Intensity changes.

Note: You may continue to change the values using the Scroll keys (and thus changing the intensity) until you press ENTER again. This allows you to experiment with the intensity level until you decide which intensity level works best for you. This feature operates in the same manner in the Rate and Duty Cycle menus.

When you have finished adjusting the intensity, press ENTER. Press Number key "7" again and the Rate menu displays. Press ENTER again. Use the Scroll keys to change the value of the the rate at which the Reticle Eyepiece blinks. As you change the value, look through the reticle to note how the Blink Rate changes.

When you have finished adjusting the rate, press ENTER. Next, Press Number key "7" again and the Duty Cycle menu displays. Press ENTER again. The Duty Cycle menu controls how long the Reticle Eyepiece Illuminator is on during a blink cycle. Use the Scroll keys to change the value. As you change the value, look through the reticle to note how the Duty Cycle changes. When you have decided on a Duty Cycle value, press ENTER.

To exit the Reticle menu, press MODE once.

RCX400TM specifications

The Meade RCX400TM is a sophisticated telescope designed for serious astronomers and astrophotographers seeking exceptional performance and innovative features. Combining advanced optics with user-friendly technology, the RCX400TM stands out as a powerful tool for both amateur and experienced stargazers.

At the heart of the RCX400TM is its revolutionary Ritchey-Chrétien optical design. This design minimizes optical aberrations, resulting in sharp, high-contrast images across the field of view. The telescope features a large aperture, typically around 10 inches, which allows for the observation of faint celestial objects, including distant galaxies, star clusters, and nebulae. The high-quality optics ensure that users can capture stunning details and nuances of their targets.

One of the standout characteristics of the RCX400TM is its advanced AutoAlign technology. This feature simplifies the setup process by automatically aligning the telescope to the night sky, enabling users to start observing in a matter of minutes. This is particularly beneficial for beginners or those who prefer a hassle-free experience when setting up for observations.

Additionally, the telescope is equipped with the Meade Smart Drive system, which enhances tracking accuracy and allows for long exposure astrophotography without the worry of trailing or blurring. This system compensates for periodic errors and undergoes continuous monitoring, ensuring that the telescope maintains precise alignment while tracking celestial objects.

The RCX400TM also incorporates an intuitive user interface with a large, easy-to-read LCD display. This interface allows users to access a comprehensive database of celestial objects, making it simple to locate and observe a wide range of astronomical phenomena. With its compatibility with various Meade accessories, such as cameras and filters, the RCX400TM provides flexibility for users looking to expand their astrophotography capabilities.

Durability is another significant aspect of the RCX400TM. Its robust construction ensures that it can withstand various outdoor conditions, making it suitable for both backyard observations and expeditions to remote dark sites.

In summary, the Meade RCX400TM is designed for those who demand high-performance optics, advanced technology, and ease of use. With features like the Ritchey-Chrétien optical design, AutoAlign technology, and the Smart Drive system, it offers a remarkable viewing experience that brings the wonders of the universe closer to all who gaze through its eyepiece. Whether for casual observation or serious astrophotography, the RCX400TM is poised to satisfy the needs of astronomy enthusiasts worldwide.
