The G1 series of CCD cameras was extended with a new model G1-1200. The Sony ICX445 CCD detector, used in this camera, is produced using EXview HAD technology and offers high quantum efficiency, comparable to cameras employing much more expensive ICX285 CCD. The 1/3" detector format (4.9 × 3.6 mm) as well as small pixels (3.75 × 3.75 μm) suit to short focal length guiding telescopes. G1-1200 is also good for capturing Moon and planets.
Physical dimensions of the Sony ICX445 CCD detector, used in G1-1200 cameras, correspond to G1-0300 or G1-0800 cameras. But G1-1200 has 1.2 millions pixels measuring only 3.75 × 3.75 μm. The EXview HAD CCD production technology, ensuring high quantum efficiency especially in near infra-red portion of the spectrum, is particularly important for usage in astronomy when capturing dim stars or other objects.
