This menu allows you to search the libraries for objects with certain parameters, much like a search engine. "Edit Parameters" lets you set various parameters for the search, and "Start Search" activates the search. A typical search might be performed as fol- lows:

1.Select "Browse" from the Object menu. Press ENTER. "Browse: Start Search" displays.

2.Press one of the Scroll Keys and "Browse: Edit Parameters" displays. Press

ENTER.

3."Edit Parameters: Largest (mins)" displays. "Mins" stands for arc-minutes. Press

ENTER.

4."Largest (mins)" and a value displays. Using the Number keys, enter a size in arc- minutes. Autostar II will search for objects up to this size and no larger. Press

ENTER.

5."Edit Parameters: Largest (mins)" displays again. Press the Scroll Down key. "Edit

Parameters: Smallest (mins)" displays. Enter the value for the smallest size of an object that Autostar II will search for in the database. Continue with "Brightest," Faintest," and "Minimum Elevation," using the procedure described in steps 3 and 4.

6.After "Minimum Elevation," "Object Type" displays. Press ENTER." "+Black Hole" displays. If you do not wish to have "Black Holes" in your search, press ENTER and the "+" changes to a "–." Press the Scroll Down key to scroll to the next item. "+Diffuse Nebula" displays. Continue to scroll through the list and press ENTER if you wish to change the "+" to a "–" or vice-versa.

7.After you have scrolled to the last item on the "Object Type" list, press MODE twice and the Scroll Down key once. "Browse: Start Search" displays. Press ENTER. "Start Search: Next" displays. Press ENTER. Autostar II searches the database and displays the first object that matches the search parameters you have entered. Use the scroll keys to display information about the object. Press MODE and "Start Search: Next" displays again. Press ENTER and the next item matching the parameters displays. Repeat this procedure to display all the objects.

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.
