About SBIG Aluma 814 Camera
Aluma 814 Camera
9 megapixel high-performance CCD with 3,69 micron pixels, compatible with iOS, Android, Windows, Macintosh, and Linux
Our mid-size SBIG 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 includes two-stage cooling, USB 2.0 and 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, FW8G-Aluma filter wheel with built-in autoguider, AO-8A Adaptive Optics accessory, Remote Guide Head, and CLA lens adapters.
Aluma is designed to operate either via USB 2.0 or WiFi 802.11 b/g/n. 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 AL for Windows. In addition our new Aluma software for iOS and Android is under development. Aluma also supports third-party applications through ASCOM and native SBIG 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).
The Aluma 814 has electronic shuttering, allowing a minimum exposure of just 0.001s. In addition it has a high reliability mechanical shutter, which facilitates accurate dark/bias calibration frames.
Efficient 2-Stage TE cooling
The Aluma uses two-stage TE cooling, twin variable-speed fans and a heat sink design optimized using computer thermal flow simulation. This permits high performance using air cooling only.
High Performance ICX-814 Image Sensor
The Aluma 814 uses the popular 9 megapixel SONY ICX-814ALG sensor. This sensor has 3388 x 2712 pixels at 3.69 microns square, for a 14.6 mm x 12.8 mm optical format.
This is a high sensitivity interline CCD sensor with extremely low dark current and very low read noise. Combining this high-performance sensor with Aluma’s high cooling performance and low readout noise results in exceptionally clean images.
This sensor includes microlens technology that concentrates light on the sensitive area of each pixel.
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.
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 cameras 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 “CLA” adapters facilitate using the FW8S-Aluma with standard Canon and Nikon camera lenses.
For astronomical imaging, the wheel is available in the FW8G-Aluma configuration. This adds a built-in focal reducer and autoguider. The pick-off mirror and guide camera focus can both be adjusted and locked using simple thumbscrews. With the autoguider positioned in front of the filters, optimum guiding sensitivity is provided for all filter slots. Using a built-in autoguider system eliminates issues with flexure, mirror shift, and other mechanical problems that can degrade guiding accuracy.
The FW8G-Aluma is thicker and does not permit use of CLA lens adapters. Interchangeable plates are available to switch your wheel between FW8G and FW8S configuration.
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.
