    ASI294MC Pro - Overview

    Like the ASI294MC Pro, the ASI294MM Pro is the first camera in the world to feature Sony's cutting-edge IMX294CJK sensor. Renowned for its exceptional performance and affordability, this camera is a favorite among astrophotography enthusiasts.

    Back-illuminated Sensor

    Enhances sensitivity while reducing noise.

    4/3” Format with 4.63 µm Pixels

    Perfect for various telescope types.

    14-bit ADC with 13 Stops Dynamic Range

    Ensures high-quality imaging with exceptional detail.

    High Resolution

    Operates at 8288×5644 in unlocked Bin1 mode and 4144×2822 in Bin2 mode.

    Ultra-low readout noise

    Just 1.2e- with a peak QE value of approximately 90%.

    Cooling System

    Two-stage TEC cooling reduces sensor temperature by over 35°C below ambient.

    ASI294MC Pro - IMX294CJK Sensor

    IMX294CJK Sensor: Advanced Technology at its Core

    The ASI294MM Pro features Sony’s IMX294CJK sensor, offering a 4/3 format with expanded diagonal and enhanced pixel performance. This sensor supports true 4K output at high frame rates, making it perfect for astronomic imaging.

    Unlocked Bin1 Mode

    This mode increases resolution and reduces pixel size to 2.3 μm, ideal for detailed object imaging. However, note the trade-offs: larger file sizes, reduced dynamic range, and lower ADC bit depth. Switch to Bin2 for larger pixel size, higher dynamic range, and improved light capture.

    Cooling System for Extended Exposures

    The camera’s two-stage TEC cooling minimizes dark current, even during long exposures. Dark current suppression technology ensures negligible noise, achieving as low as 0.0022e/s/pixel at -20°C.

    Exceptional Design

    Sealed sensor chambers prevent issues like dew formation, ensuring stable operation even in high-humidity environments.

    ASI294MC Pro - Enhanced Connectivity and Accessories

    Connectivity

    USB 3.0 Port: High-speed data transfer at up to 5Gb/s.

    Integrated USB 2.0 Hub: Simplifies cable management by connecting accessories like filter wheels and electronic focusers.

    Reliability

    The DDR3 memory buffer prevents frame drops during long exposures, reducing glow artifacts.

    Additional Features

    HCG Mode: Automatically activates at higher gain (≥120) to reduce noise without sacrificing dynamic range.

    QE Value: Backside illuminated sensor achieves a QE peak of approximately 90%.

    Dark Current Performance: Significantly lower than previous models, enhancing performance in low-light conditions.

    Recommended Accessories

    Recommended Accessories: For optimal use, consider purchasing a 12V power adapter or compatible lithium battery for powering the camera.

    Setup Instructions

    1. Connect the ASI294MM Pro to an 11-14V power supply. This is required even if the cooler isn't being used.
    2. To enhance convenience, use ASIAIR for powering the camera.
    3. Ensure the USB 3.0 cable is securely connected for high-speed data transmission.
    4. If utilizing the cooling function, use a 12V/3A DC adapter or lithium battery for stable performance.
