The DS-142M ICE Peltier cooled camera with fan-assist is a native 1.4 mega-pixel 16-bit greyscale CCD imager with a large and very sensitive Sony SuperHAD Chip of 1/2" diagonal (ICX205AL).
The DS-142M ICE uses the all new Z-MAX high-speed platform which adds a host of desirable features to this high quality camera.
Unlike other cameras in its class, gain support, noise reduction and black level are all implemented in the camera hardware and applied to the signal prior to the data been sent to the PC, thus ensuring the highest quality signal and brightest image possible at typical speeds of 3.5fps @ 1434x1050 in uncompressed RAW format.
A substantial heatsink, over five times the mass of the typical heatsink in comparable cameras, rapidly draws the heat away from the sensor via a powerful Peltier thermocouple. This heat is then rapidly dissipated into the atmosphere with the assistance of an essential 60mm diameter fan thus bringing noise levels down to a minimum.
The camera's advanced features can easily be demostrated in StarView. The StarView mode is a real time video mode with exposure times up to 10 seconds per frame. There is no need to use any bias frames. Deep sky objects become visible in real time, making focusing much easier and quicker.
The StarView mode above demonstrates the Gain function in real time (10 second exposures). The image on the left has 100% Gain applied to it. The image on the right has 50% Gain applied to it. These images do not use any dark/flat/bias frames. In StarView mode the images are shown in colour as standard. Although StarView is part of the camera runtime software, it is accessible from Nebulosity, AstroArt and MaxIm DL.
Screen shots shown form the colour version of the camera. The monochrome version is approximately 2.5 times more light sensitive.
The Gain function does not simply boost the signal evenly, it also improves the signal-to-noise (S/N) ratio dramatically. In fact, as the Gain increases the S/N ratio increase is 10:1. This is possible due to the camera's build-in noise reduction electronics.

High Quality Construction
The camera electronics and sensor are housed inside a high quality aluminium body that entirely seals the sensor and on-board electronics from the outside environment. This is important as it protects the camera internals from high humidity and water running down the telescope and into the camera damaging the electronics or sensor, quite common in inadequate camera designs.
The camera relies for fast data transfers on an efficient USB2.0 sub-system specially designed for the DS-142M ICE. The camera is powered via a high quality regulated mains power supply included with the camera and comes with all cables, adapters and software needed to be able to use the camera out of the box.
Nebulosity is designed to be a powerful, but simple to use camera control and image processing application for Opticstar CCD cameras. Its goal is to suit people ranging from the novice imager who wants to create his or her first images to the advanced imager who wants a convenient, flexible capture application for use in the field. In it, you get a host of purpose-built powerful tools to make the most out of your images (e.g., Digital Development Processing, traditional alignment/stacking (equatorial and alt-az), Drizzle alignment/stacking, Bad Pixel Mapping, real-time tricolour histograms for colour balancing, star tightening via edge detection, adaptive scaling of stacks, Canon CR2/CRW RAW Bayer matrix loading, 32/96-bit accuracy, etc.)
Opticstar Deep Sky CCD Cameras
Cooled, long exposure cameras for deep-sky imaging and scientific applications.
Our Deep Sky Multi-Pixel CCD Cameras are astonishing each using advanced technology from Sony which is at the forefront of our DS series cameras. The Opticstar XL's are thermo electrically cooled for long exposure image capture enabling our XL cameras to achieve higher performance levels than other Sony CCD based cameras! Due to their advanced electronics, incorporating real hardware gain, noise suppression & superior cooling our XL cameras are 50% more light sensitive in practical use (100% max) than any other competing camera on the Market! Our 142 and 145 series are both use by Nasa, the US Army and the Japanese Space agency...They are just that good!
The new Opticstar XL cameras use precision machined heavy duty aluminum alloy cases that provide unparalleled solidity and support sensor orthogonality. The camera uses long-life, high quality seals and offer 99%+ camera window transparency. A substantial heat-sink (five to ten times the mass of the typical heat-sink in comparable cameras) rapidly draws the heat away from the sensor via a powerful Peltier thermocouple for superior performance. This heat is then rapidly dissipated into the atmosphere with the assistance of a fan thus bringing noise levels down to an absolute minimum.
The larger than usual Sony 1/1.8” format CCD sensor offers a wide field of view allowing easier framing of larger deep-sky objects. Focus and preview modes run at a maximum 5 frames per second even at full resolution ( 3032x2014 ) which is many times faster than other single shot astronomy cameras, which makes critical focusing markedly easier to achieve!
The proprietary StarView mode enables semi real time viewing of deep sky objects in color with an incredible 3600% sensitivity boost with exposure times at up to 1ms and 1 hour, a very useful feature not available to other manufacturers’ single shot cameras!
Bundled with the camera, is a main power supply unit to power the thermo-electric cooling sub-system, 1 hard shell carrying case and adapters to attach the camera to the telescope. The camera also includes Nebulosity v2.0 camera control and image processing software as well as drivers for MaxImDL and Astroart. Exceptional Quality - COPIED but Never Equaled!!!
