SBIG Aluma 3200 Mono High QE camera
Available on backorder
The 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, AO-8A Adaptive Optics accessory, StarChaser SC-2 Off-Axis Guider, 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. 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.
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).
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.
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 the even-illumination shutter.
HIGH-PERFORMANCE KAF-3200 IMAGE SENSOR
The Aluma 3200 uses the extremely sensitive 3.2 megapixels ON Semi (formerly Kodak) KAF-3200-ABA sensor. The sensor has 2184 x 1472 pixels at 6.8 microns square, for a 14.85 mm x 10.26 mm optical format.
The KAF-3200 has perhaps the best quantum efficiency of any front-illuminated CCD sensor, peaking at over 80%, and it has low dark current and low read noise. Combining this high-performance sensor with Aluma’s high cooling performance and low readout noise results in exceptionally clean images.
KAF-3200 Quantum Efficiency
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.
