computer control panel/ Plug the other end into a USB port of your PC Next, you will install the Autostar Suite software from the CD ROM. This software pro- vides a menu that allows you to download the latest version of Autostar II software into the Autostar II handbox.

4.Select Autostar Suite on the CD ROM to install Autostar Suite onto your PC. Follow the on-screen instructions.

5.Once the Autostar Suite software installs, double-click the new “Autostar Suite” icon on the desktop.

6.Go to the Telescope menu and select “Update Autostar.” The “Autostar Update” screen displays. Click the “Upgrade Autostar Software Now” button.

7.The application detects your telescope type and the version of Autostar soft- ware on your handbox.

8.A window displays asking if you wish to download the latest version of Autostar from your hard drive (if you previously downloaded it separately from the Meade website) or from the internet. Select one of the choices and follow on-screen instructions.

9.The download will take several minutes (download time depends on your inter- net connection, speed of your computer and so forth). When the download is complete, the new version of the Autostar software displays.

Periodic Error Correction

If you wish to perform high-precision astrophotography, you may wish to "train" your telescope in order to keep objects that you are imaging dead center in the telescope's field of view during the photographic exposure. Periodic error correction (PEC) helps to remove the slight perturbations from center that occur due to the mechanical nature of a telescope. To perform this procedure, you need to use a high-power reti- cle, such as the 9mm reticle (see OPTIONAL ACCESSORIES, pages 48 - 50). PEC training is available for both drives.

Train Menu Option

Important Note: The Train option overwrites any previous PEC data.

1.Select "Train" from the RA PEC menu (in the "Setup: Telescope" menu) and press

ENTER.

2.Look through the reticle. Use the Arrow keys to keep the star centered in the reticle cross-hairs. Autostar II displays a count of the 75 positions of the worm gear. When the count reaches 75, one cycle is complete. A full cycle takes about 20 minutes.

3.Select "Train" from the R.A. PEC menu (in the "Setup: Telescope" menu) and press

ENTER.

4.Press MODE to exit.

Update Menu Option

Use the Update option to further refine your training; it is recommended that you update your original training two or three times when first using your telescope. Update does not overwrite the data, but updates the training using information gath- ered from both the last and the current training sessions. Press the MODE key to exit from this option. If you wish to further refine your training, select this menu again and repeat the procedure.

Erase Menu Option

Select this option to erase all PEC training data.

On and Off Menu Options

Select "On" when you want the telescope to use the training information. Select "Off" when you do not want for the telescope to use the training information. Select "On" to enable the Smart Drive.

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.
