Helpful Hint

GoTo Object: To go to any of the user defined objects stored in the database, scroll down to either GoTo Sky Obj or Goto Land Obj and enter the number of the object you wish to select and press ENTER. The telescope will automatically retrieve and display the coordinates before slewing to the object.

Save Sky Object: Your telescope stores celestial objects to its database by saving its right ascension and declination in the sky. This way the same object can be found each time the telescope is aligned. Once a desired object is centered in the eyepiece, simply scroll to the "Save Sky Obj" command and press ENTER. The display will ask you to enter a number between 1-200 to identify the object. Press ENTER again to save this object to the database.

Enter R.A. - Dec: You can also store a specific set of coordinates for an object just by entering the R.A. and declination for that object. Scroll to the "Enter RA-DEC " command and press ENTER. The display will then ask you to enter first the R.A. and then the declination of the desired object.

Save Land Object: The telescope can also be used as a spotting scope on terrestrial objects. Fixed land objects can be stored by saving their altitude and azimuth relative to the location of the telescope at the time of observing. Since these objects are relative to the location of the telescope, they are only valid for that exact location. To save land objects, once again center the desired object in the eyepiece. Scroll down to the "Save Land Obj" command and press ENTER. The display will ask you to enter a number between 1-200 to identify the object. Press ENTER again to save this object to the database.

To replace the contents of any of the user defined objects, simply save a new object using one of the existing identification numbers; the telescope will replace the previous user defined object with the current one.

Get RA/DEC - Displays the right ascension and declination for the current position of the telescope.

Goto R.A/ Dec - Allows you to input a specific R.A. and declination and slew to it.

To store a set of coordinates (R.A./Dec) permanently into the database, save it as a User Defined Object as described above.

Identify

Identify Mode will search any of the telescope's database catalogs or lists and display the name and offset distances to the nearest matching objects. This feature can serve two purposes. First, it can be used to identify an unknown object in the field of view of your eyepiece. Additionally, Identify Mode can be used to find other celestial objects that are close to the objects you are currently observing. For example, if your telescope is pointed at the brightest star in the constellation Lyra, choosing Identify and then searching the Named Star catalog will no doubt return the star Vega as the star you are observing. However, by selecting Identify and searching by the Named Object or Messier catalogs, the hand control will let you know that the Ring Nebula (M57) is approximately 6° from your current position. Searching the Double Star catalog will reveal that Epsilon Lyrae is only 1° away from Vega. To use the Identify feature:

Press the Menu button and select the Identify option.

Use the Up/Down scroll keys to select the catalog that you would like to search.

Press ENTER to begin the search.

Note: Some of the databases contain thousands of objects, and can therefore take several minutes to return the closest objects.

C5-S, C9-S, C8-S specifications

Celestron, a leader in the field of amateur and professional astronomy, offers a range of telescopes ideal for both novices and experienced stargazers. Among their most celebrated models are the C8-S, C5-S, and C9.25-S, each designed with unique features and technologies that enhance the observational experience.

The Celestron C8-S is an iconic telescope known for its 8-inch aperture. This Schmidt-Cassegrain design combines a compact form factor with a powerful light-gathering capability, making it perfect for deep-sky observing. Its optical tube has a focal length of 2032mm, providing an excellent balance of wide field viewing and high magnification. The C8-S features Celestron's StarBright XLT optical coating, enhancing light transmission and contrast, ensuring that even faint objects are visible. With compatibility for various accessories and a sturdy mount, the C8-S stands as a versatile option for different observing styles.

Moving to the C5-S, this model boasts a 5-inch aperture while maintains a compact and portable design. It is particularly popular among travelers and casual astronomers who value convenience without compromising on quality. The C5-S also employs the Schmidt-Cassegrain design, providing sharp images and improved color correction. With its shorter focal length of 1250mm, the C5-S excels in both planetary and deep-sky observation. The telescope's lightweight build makes it easy to transport, while the integrated optical systems ensure a clear view of celestial objects.

The C9.25-S represents a step up in performance, featuring a 9.25-inch aperture that captures more light than its smaller counterparts. This telescope offers a versatile focal length of 2350mm, allowing for impressive high-power planetary views, as well as detailed observations of deep-sky objects. The C9.25-S utilizes a unique StarBright XLT coating and features advanced optics that minimize optical distortion, resulting in sharp, high-contrast images. It is equipped with a sturdy mount that ensures stability during extended observation sessions.

All three models are compatible with Celestron's advanced computer-driven mount systems, allowing for effortless tracking and alignment.
