The ST-2000XCM camera is single shot color version of the ST-2000XM monochrome cameras, This single shot color version uses KAI-2020CM color CCD. This is essentially the same CCD as the KAI-2020M used in the ST-2000XM monochrome camera with the exception of an RGB filter matrix over the pixel array. All the other features are the same as the monochrome versions of the camera:
A relatively large CCD with a generous field of view - nearly the same size as the ST-8XME
More than a million pixels - nearly two megapixels
Antiblooming protection - good for small refractors
High resolution on smaller telescopes with 7.4 micron square pixels
Flexibility of binning 2x2 on larger scopes with good image size
Self-guiding with a built-in TC-237H CCD
Remote Guide Head Port
High speed download - about 4.5 seconds for a full 1.9 megapixel image
Professional software - see below
Easy to use
Full compliment of optional custom accessories
SBIG quality and support
Like their monochrome counterparts, the ST-2000XCM and ST-2000XCMI cameras are the same, except that the ST-2000XCMI does not have the built-in TC-237H tracking CCD and some of the accessories that are included with the ST-2000XCM (see the comparison table below). In March of 2006 SBIG added the Remote Guide Head Port to both the single sensor ST-2000XMI and dual sensor ST-2000XM cameras. Both versions use a high quality interline CCD from Kodak, the KODAK DIGITAL SCIENCEř KAI-2020CM Image Sensor Megapixel Progressive Scan Interline CCD. The KODAK DIGITAL SCIENCETM KAI-2020CM is a high-performance multi-megapixel image sensor designed for a wide range of scientific, medical imaging, and machine vision applications. The 7.4 mm square pixels with microlenses provide high sensitivity and the large full well capacity results in high dynamic range. The vertical overflow drain structure provides antiblooming protection, and enables electronic shuttering for precise exposure control to 0.001 seconds. Other features include low dark current, negligible lag and low smear. The KAI-2020CM CCD is a 2 megapixel progressive scan detector with an active image area of 1.92 million pixels. The active image area is 1600 x 1200 pixels. This array is 75% larger than the Sony CCD used in competitors' "one-shot color megapixel" cameras, nearly as large as an ST-8XME, and the ST-2000XM is a self-guiding camera, utilizing SBIG's patented dual sensor design. Although the imaging CCD is nearly the same size as the KAF-1602E used in the ST-8XME, due to the smaller pixel size it contains nearly half a million more pixels than the ST-8XME. The latest KAI-2020CM 2 megapixel CCD has all of the same improvements as the monochrome KAI-2020M: a high gain output amplifier that reduces the read noise by almost half compared to the previous CCD, 10X fewer bright points, and lower dark current. The ST-2000XCM also has the larger 657x495 pixel TC-237H built-in guiding CCD instead of the TC-211. This improvement was the same as the upgraded autoguider installed on the larger ST-8XE, ST-9XE and ST-10XE cameras.
In May of 2004 SBIG began including a custom Pelican carrying and storage case with the ST-2000XM and ST-2000XCM models. This case is dustproof, waterproof and crushproof and carries a lifetime guarantee from Pelican. As of the date of this announcement, we are also upgrading the version of TheSky software by Software Bisque that we include with the ST-2000XCM camera from version 4 to version 5, a $129 value. If you have a Macintosh computer running OS-X we will even throw in Equinox camera control and planetarium software for the Mac as well! A Linux acquisition program is free and other Linux software is also available. We continue to include CCDSoftV5 in addition to CCDOPS version 5 the most complete package of camera control, image processing, astrometric, star charting and planetarium software available with any new CCD camera from any manufacturer. Upgrades are available for most of these improvements for older ST-2000XM camera owners. All of these improvements have come at no additional increase in the price of the ST-2000XCM camera.
The full frame download time is approximately 4.5 seconds with our high speed USB electronics. This camera is also fully compatible with all of our existing accessories such as the CFW8 filter wheel and AO-7 adaptive optics device. Because the ST-2000XCM has two CCDs (a guiding CCD as well as an imaging CCD) in the same camera head, it is capable of self-guiding without any compromise in the quantum efficiency of the imaging CCD. In other words, not only CAN it self-guide, it can do so without having to double the exposure time to compensate for the guiding feature.
The ST-2000XCM is a complete camera system. There is no need to add in the additional cost of an interface or an autoguider or a nosepiece or better software to make these cameras actually operate as they should. Everything that is needed to make the camera operational is included in the base price. We even include some non-essential, but desirable, items such as a custom hard carrying case.
Each new ST-2000XM camera system INCLUDES at no additional cost:
Rugged camera body with imaging and autoguiding CCDs and new analog and digital electronics
