Multi-Platform Operation

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.

Software Included

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).

Mechanical Shutter

The Aluma 694 has electronic shuttering, for a minimum exposure of 0.001s.  In addition it has a high reliability mechanical shutter, which facilitates accurate dark/bias calibration frames.

High Performance ICX-694 Image Sensor

The Aluma 694 uses the popular 6 megapixel SONY ICX-694ALG sensor. This sensor has 2750 x 2200 pixels at 4.54 microns square, for a 14.6 mm x 12.8 mm chip size.

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.  The CCD’s sensitivity peaks in the center of the visible spectrum at 550 nm, and maintains high sensitivity throughout the visible spectrum.  The ICX-694 is particularly good in the blue compared to other sensors on the market.

SmartCoolingTM

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.

Included Accessories

  • MaxIm LT software – 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

FW8G-Aluma is a self-guiding 8-position filter wheel for the Aluma Series cameras.  This wheel has a guiding CCD and associated optics built into the front cover, in front of the filters.

Due to the backfocus requirements, CLA camera lens adapters will not work with this cover.  A lower profile standard cover, without guider, is available as an accessory.  The standard cover is easily swapped for the self-guiding cover when imaging through a camera lens is desired.

Features

The carousel holds eight 36mm filters and inserts are available for 1.25″ filters.  The 36 mm filters provide unvignetted imaging for the largest Aluma sensors.

Aluma wheels include 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 left-hand image below 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 FW8G-Aluma includes a built-in focal reducer and autoguider.  The pick-off mirror and 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.
