ST-2000XCM and ST-2000XCMI
Multi-megapixel Color CCD Cameras

The ST-2000XCM and ST-2000XCMI cameras are single shot color versions of the ST-2000XM and ST-2000XMI monochrome cameras,  These single shot color versions use 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
• Good sensitivity
• Low noise
• 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
• Lower price
• 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 we 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 SCIENCE™ KAI-2020CM Image Sensor Megapixel Progressive Scan Interline CCD.  The KODAK DIGITAL SCIENCE^TM 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.
