Other Celestron 93713 telescope accessory Black

The Celestron 93713 telescope accessory in black is a stand-alone autoguider designed to improve tracking accuracy for astrophotography and visual observations. Built around a SONY CCD sensor, it provides a larger imaging area and increased sensitivity to help locate and maintain lock on fainter guide stars. The unit is intended to be used without a laptop, with onboard controls and a battery-powered option for field use, and features a standard 1.25" eyepiece ring for centering and focusing.

Advantages

The stand-alone design removes the need for a laptop during guiding sessions, simplifying field setups. A sensitive CCD sensor and enlarged chip area increase the likelihood of finding suitable guide stars and maintaining stable tracking. Automatic calibration for each axis and automatic guide rate parameter setting reduce setup time and user intervention. Battery operation and an optional DC power input allow flexible power choices for remote observing locations. A 9-button hand control offers direct menu navigation and faster operation.

Suitable for

• Astrophotography with DSLR cameras
• Long-exposure imaging where precise tracking is required
• Field use without access to mains power
• Observers who prefer a compact autoguider without a laptop

Key specifications

• Image sensor type: SONY CCD
• Chip dimensions: 5.6 mm × 4.7 mm
• Pixel size: 9.6 µm × 7.5 µm
• Eyepiece interface: standard 1.25" ring for centering and focusing
• Power options: 4 D-cell batteries (not included) or optional DC power supply
• Control: 9-button handheld controller for menu navigation
• Functionality: stand-alone autoguider with automatic calibration of each axis and automatic guide rate parameter setting

How to use

Mount the autoguider securely on the telescope using the standard attachments, insert a 1.25" eyepiece if required for centering, and connect the guider to the mount following the mount manufacturer's guiding input procedure. Power the unit with four D-cell batteries or an appropriate DC power supply. Use the 9-button hand control to navigate menus, initiate automatic calibration for each axis, and allow the device to set guide rate parameters. Once a guide star is centered on the sensor, begin guiding and proceed with DSLR imaging or other long-exposure tasks.

Usage recommendations

For best results, choose nights with steady seeing and align your mount accurately before starting the autoguider calibration. Use fresh batteries or a stable DC power source for extended sessions, and verify guide star selection on the larger chip area to ensure continuous tracking during long exposures.
