Our mid-size high performance Aluma® Series cameras offer capabilities 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 includes two-stage cooling, USB 2.0 and optional WiFi 802.11 b/g/n interfaces, ultra-reliable even-illumination shutter, and fast low-noise readout. Aluma can be operated from a tablet or smartphone, or 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, StarChaser SC-2 off-axis guide camera, AO-8A Adaptive Optics accessory, and Remote Guide Head.
Aluma is available in two versions – standard version with USB and WiFi interface, and the lower-cost Aluma U series with only the USB interface.

Aluma is designed to operate via USB 2.0 and optionally WiFi 802.11 b/g/n. Designed from the ground-up to support operation on any modern computing platform, Aluma is compatible with 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.
All Aluma models ship with MaxIm LT for Windows – a special version of MaxIm DL specific to our 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).
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 are 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.
The left image shows a flat field image taken with a camera using an iris type shutter. The right image is a flat field image taken under the same conditions using our even-illumination shutter.
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 chip size.
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 our 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.
Advanced Software Included
All SBIG cameras come with our MaxIm LT software – a $200 value! MaxIm LT is a special version of our venerable MaxIm DL software for Windows that provides complete control of your camera, filter wheel, and autoguider, plus advanced image processing capabilities. If you wish you can upgrade to MaxIm DL Pro to get complete observatory integration and even more processing and analysis capabilities.
Each Aluma camera package includes:
- MaxIm LT software (Windows) – please use this form to request your license
- Deluxe carrying case
- Universal power supply (110V / 220V, 50-60 Hz)
- 2″ Nosepiece adapter
- USB flash drive containing software, drivers, and documentation
- 15 foot (4.5 m) USB cable
- Tracking interface cable
Optional Micron-Precision Filter Wheel
The optional FW8S-Aluma 8-position filter wheel includes a positive centering mechanism that precisely centers each filter in the exact same position every time. This single-pixel accuracy completely eliminates ghost images of dust spots and other artifacts after flat-fielding.
Positive detent mechanism provides single-pixel filter position accuracy
Precision flat-fielding with utlra-accurate indexing
The left-hand image shows a dust spot on the filters. A flat-field calibration frame was taken, then the filter wheel was rotated several times before taking a second picture, which was flat-field calibrated, at right. No evidence of the dust spot is visible. This high precision results in the highest quality images and excellent photometric accuracy.
The Aluma wheel holds standard 36 mm filters, and inserts are available for 1-1/4″ filters, which are suitable for smaller format CCD sensors.
The Aluma filter wheel replaces the camera’s front plate, resulting in the minimum possible back-focus, ensuring that the camera / filter wheel combination will reach focus on the widest possible variety of optical systems.
Optional StarChaser SC-2 Off-Axis Guide Camera
For astronomical imaging the Aluma series works the the StarChaser SC-2 Off-Axis Guide Camera. This provides reliable guiding with no impact from optical train flexure. It also supports operation of the optional AO-8A Adaptive Optics accessory.
Optional AO-8A Adaptive Optics
All Aluma models can operate with the AO-8A Adaptive Optics accessory. The AO-8A uses a tip-tilt window to quickly and precisely adjust the image position in response to autoguider feedback. With Adaptive Optics there is no backlash, stiction, or lag, and the movements are extremely precise and accurate. This allows the AO-8A to not only remove the effects of periodic error, drift, and wind gusts, but also reduce the effects of atmospheric seeing.
For more information please see AO-8T.
