SBIG StarChaser to AO-X/AO-8T Adapter Cable
The SBIG StarChaser to AO-X/AO-8T Adapter Cable is the essential link for integrating modern SBIG guide cameras with legacy and large-format accessories. This cable bridges the compact Mini DIN 9 connector found on cameras like the StarChaser series to the male DE9 (DB9) plug required by adaptive optics units and filter wheels, carrying the AUX/I2C connection between them.
Bridging SBIG Generations: Mini DIN 9 to DE9 Connectivity
As SBIG cameras have evolved, connector types have changed. This adapter solves the physical incompatibility between compact cameras using the Mini DIN 9 port and accessories built with the larger DB9-style AUX/I2C connector.
-
Mini DIN 9 Compatibility: Designed for the output ports on the StarChaser, Aluma CCD, Aluma AC455, STC-7, and STC-428 cameras.
-
Male DE9 Compatibility: Connects directly to the "I2C IN" port on the AO-X, the DB9 pigtail on AO-8T and AO-8 units, AFW filter wheels, and older filter wheels with female DB9 pigtails.
The Essential Link for AO-X and AO-8T Adaptive Optics
For imagers using an SBIG StarChaser guider with an AO-X or AO-8T adaptive optics unit, this is the specific cable required to make the system work. A single adapter cable between the StarChaser SC-4 and the AO-X provides all necessary power and control signals. Since the AO unit is controlled directly by the StarChaser, it is independent of the main camera.

What is the purpose of the SBIG StarChaser to AO-X/AO-8T Adapter Cable?
This cable adapts the modern Mini DIN 9 connector found on compact SBIG cameras and guiders to the larger DE9 (DB9) connector used on accessories like the AO-X, AO-8T, and various filter wheels. It allows different generations of SBIG equipment to communicate correctly.
I have a StarChaser SC-4 and an AO-X. Is this the correct cable to connect them?
Yes, this is the exact cable required. A single adapter cable between the SC-4 and AO-X provides all necessary power and control signals, enabling the two devices to work together as an integrated adaptive optics system.
Which SBIG cameras use the Mini DIN 9 connector that requires this adapter?
The SBIG StarChaser to AO-X/AO-8T Adapter Cable is needed for cameras that feature the Mini DIN 9 port. This includes:
- StarChaser Models (e.g., SC-4)
- Aluma CCD
- Aluma AC455
- STC-7
- STC-428
Which SBIG accessories can I connect to with this cable?
The male DE9 end of the SBIG Adapter Cable is compatible with a range of accessories that use a female DB9 port or pigtail for I2C/AUX control. This includes:
- AFW Filter Wheels
- AO-X (via the "I2C IN" port)
- AO-8T and AO-8 (via DB9 pigtail)
- FW7 (via DB9 pigtail)
- Older filter wheels with female DB9 pigtails
Do I need the SBIG Adapter Cable for an AO-8A adaptive optics unit?
No. The SBIG AO-8A has a built-in mini-DIN cable and is designed to plug directly into compact format cameras like the StarChaser SC-4C without needing this adapter.
How does the SBIG Adapter Cable handle control signals?
The cable is wired to pass control signals using the I2C protocol. This is the communication standard SBIG uses for devices like the AO-X to receive commands from a guide camera, such as the AO-X tip-tilt corrections.
