OpticStar DS-142M 1/2" Monochrome CCD Camera
The DS-142M Peltier cooled camera with fan-assist is a native 1.4 mega-pixel 16-bit monochrome CCD imager with a large and very sensitive Sony SuperHAD Chip of 1/2" diagonal (ICX205AK). The OpticStar DS-142M 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 maximum speeds of 2.5fps @ 1434x1050 in uncompressed RAW format.
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 or perform any colour synthesis. StarView outputs the images in colour by default. Deep sky objects become visible in real time, making focusing much easier and quicker. 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.
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 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. 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.
The included Nebulosity software 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.)
