More information

  • ASI294MC - Overview

    The ASI294MC is the world's first astronomic camera sensor adopting the Type 4/3 format with expanded diagonal dimensions to 23.2mm (Approx. 11.71M effective pixels).

    Sony IMX294CJK Sensor

    The world's first astronomic camera sensor adopting the Type 4/3 format with expanded diagonal dimensions to 23.2mm (Approx. 11.71M effective pixels).

    High Sensitivity

    Back-illuminated design ensures exceptional performance in low-light conditions, with an SNR1s of 0.14 lx and 4.63 μm pixel size.

    Advanced 14-bit ADC

    Provides a high dynamic range of 13 stops, outperforming the ASI1600 in image quality.

    Large Full Well Capacity

    63,700e full well capacity minimizes star saturation during long exposures.

    HCG Mode

    Automatically activates at gain levels above 120, reducing read noise to under 2e while maintaining a 13-stop dynamic range.

    Quantum Efficiency (QE)

    BSI sensor with a peak QE exceeding 75%, maximizing light capture efficiency.

    ASI294MC - IMX294CJK Sensor

    Low-Light Performance

    The IMX294CJK sensor is tailored for astronomy applications requiring outstanding low-light sensitivity. With a large 4.63 μm pixel size and back-illuminated design, the ASI294MC delivers detailed and noise-free images, even under challenging conditions.

    Dynamic Range and Full Well Capacity

    The camera's 14-bit ADC provides 13 stops of dynamic range, capturing a greater range of details in high-contrast scenes. The impressive 63,700e full well capacity prevents saturation of bright stars, ensuring excellent signal-to-noise ratios with single exposures.

    High-Speed Operation

    The USB 3.0 interface supports a frame rate of 16 fps at 14-bit normal mode and 19 fps at 12-bit high-speed mode, making the ASI294MC ideal for a variety of applications, from deep-sky imaging to fast planetary captures.

    Quantum Efficiency (QE)

    The IMX294 sensor’s high QE and back-illuminated structure maximize light collection efficiency, making it a versatile choice for astrophotography enthusiasts.

    Setup Instructions

    1. Connect the ASI294MC to your computer via the USB 3.0 port, which provides a 5Gb bandwidth for smooth operation at full resolution.
    2. For guiding, link the camera to your mount’s auto-guide port using the ST4 port.
    3. Adjust gain settings to suit your imaging needs. When set above 120, the HCG mode will engage automatically, reducing readout noise.
    4. Use appropriate filters or accessories to optimize imaging for specific targets or conditions.
