azimuth housing. While standing behind the telescope, the knobs are on the front of the mount.

•Turning the right adjustment knob clockwise moves the mount toward the right.

•Turning the left adjustment knob clockwise moves the mount to the left.

Both screws push off of the peg on the tripod head, which means you may have to loosen one screw while tightening the other. The screw that holds the equatorial mount to the tripod may have to be loosened slightly.

Keep in mind that adjusting the mount is done during the polar alignment process only. Once polar aligned, the mount must NOT be moved. Pointing the telescope is done by moving the mount in right ascension and declination, as described earlier in this manual.

Attaching the Declination Cables (For GT Models Only)

The Advanced Series mount comes with a declination cable that connects from the R.A. motor drive electronic panel to the Dec motor drive. To attach

the motor cables:

• Locate the Declination cable and

 

plug one end of the cable into the

 

port on the electronics panel labeled

 

DEC Port and plug the other end of

 

the cable into the port located on the

1. To power the telescope with the car battery adapter (or 12v AC adapter), simply plug the round post into the 12v outlet on

the electronic panel and plug the other end into your cars cigarette lighter outlet or portable power supply (see Optional Accessories). Note: to prevent the power cord from being accidentally pulled out, wrap the power cord around the strain relief located below the power switch.

2.Turn on the power to the telescope by flipping the switch, located on the electronics panel, to the "On" position.

C9.25-S, C5-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. With built-in features such as GoTo technology, users can easily locate thousands of celestial objects with the touch of a button. This combination of advanced optics, portability, and user-friendly technology makes the Celestron C8-S, C5-S, and C9.25-S excellent choices for anyone looking to explore the cosmos more deeply. Whether for casual stargazing or serious astronomical study, these telescopes deliver exceptional performance to meet a variety of needs.
