Product Details

  • **This is the Broadband version of the Aluma U47-10.**

    The mid-size Aluma Series cameras offer performance and features not available in any other scientific-grade imaging camera. This lightweight (2.2 lbs) and compact (4.5″ x 4.5″ x 4″ with handles) camera include two-stage cooling, USB 2.0, ultra-reliable even-illumination shutter, and fast low-noise readout.  Aluma can be operated from a Windows, Macintosh, or Linux PC.

    The Aluma series supports a wide range of accessories, including the 8-position FW8S-Aluma filter wheel with micron-level filter positioning, FW8G-Aluma filter wheel with built-in autoguider, AO-8A Adaptive Optics accessory, and Remote Guide Head.

    Aluma Features:

    • Wide variety of imaging sensors
    • Lightweight, compact design
    • Centered optical axis for optimum instrument balance
    • Ultra reliable even-illumination (photometric) mechanical shutter
    • Support for iOS, Android, Windows, Macintosh, and Linux
    • USB 2.0 interface
    • Full frame image buffering eliminates readout artifacts and provides 100% reliable wireless download
    • 2-Stage TE cooling with typical -50C from ambient
    • Twin variable speed fans with SmartCooling technology
    • High accuracy temperature regulation
    • Built-in RBI Pre-flash (full frame front-illuminated sensors only)
    • External TTL trigger inputs and output
    • Included 110V / 220V power supply and optional 12VDC operation
    • User-rechargeable desiccant plug
    • Built-in 1/4-20 tripod mount
    • Support for high precision 8-position filter wheels
    • Support for external guide head, self-guiding filter wheels, and adaptive optics
    • Bulletproof firmware update capability – virtually impossible to “brick”

    Multi-Platform Operation

    Aluma is designed to operate via USB 2.0. Designed from the ground up to support operation on any modern computing platform, Aluma is compatible with iOS, Android, Windows, Macintosh, and Linux. Fully-documented and supported drivers are available for all platforms, including ASCOM drivers. The Aluma camera interface specification is fully documented, supporting the development of fully custom interfaces.

    Software Included

    All Aluma models ship with MaxIm LT for Windows – a special version of MaxIm DL specific to these cameras. Aluma also supports third-party applications through ASCOM and native drivers.

    Compact and Lightweight Design

    Aluma cameras measure just 4.25″ x 4.25″ x 4.0″ with handles (3.5″ without handles) and weigh just 2.2 lbs (1 kg).

    Even-Illumination Shutter

    All Aluma cameras include a mechanical shutter, which is used for both dark/bias calibration frames and for shuttering exposures on full frame sensors. Rather than using a complex iris shutter, which is prone to failure, the Aluma uses a twin vane shutter and direct drive motor for high repeatability, reliability, and extremely long life. The shutter is designed to be “even illumination” for the best accuracy in photometric measurements.

    Extreme Sensitivity CCD 47-10 Image Sensor

    The Aluma 47-10 uses the 1 megapixel E2V CCD 47-10 sensor, featuring peak quantum efficiency (QE) of 93% with midband coatings. This full frame, back-illuminated sensor is designed for the ultimate in sensitivity. The sensor is available with midband, broadband, and UV coatings to optimize performance in different spectral regions. Midband is the default coating.

    CCD 47-10 Quantum Efficiency Curves

    The CCD 47-10 has 1056 x 1027 pixels at 13 microns square, for a 13.3 mm square optical format.

    This back-illuminated full-frame CCD sensor has extremely low noise and extremely high sensitivity. Combining this high-performance sensor with Aluma’s high cooling performance and low readout noise results in exceptionally clean images.


    All Aluma cameras include the powerful new SmartCooling technology. The two-stage cooler, powerful fans, and advanced heat sink designed using thermal flow simulation combine to produce typical cooling delta from ambient of -50C. This is quite a feat considering the Aluma’s very compact and lightweight package.

    SmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption. The camera’s firmware is constantly monitoring the sensor and heat sink temperatures, as well as controlling the cooler power. When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling.  When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.
