The Moravian Instruments G3-16200 Monochrome CCD Camera uses a new semi-large format low noise, high quantum efficiency KAF-16200 Class 1 CCD Sensor.

While other astronomical cameras use CCD chips primarily designed for different application fields, KAF-16200 had “astronomy imaging” stated as the primary application during its development. Sensor dimensions 27.2 × 21.8 mm (35 mm diagonal) are designed for 2" focusers and correctors, often using M42 or M48 threads. Sensor aspect ratio 5:4 which is very close to square. This is an optimal fit for an aberration-free circle within the field of view, but also large enough to allow the best composition of the image. The sensor is small enough to be used with 2" filters (or unmounted D50mm filters), which are more common and affordable compared to square 50 × 50mm filters. Also more filters can fit into the same filter wheel and the G3 design allows usage of an internal filter wheel. 6 × 6μm pixels perfectly correspond to the typical focal lengths of amateur telescopes (between 50 and 150cm). Smaller pixels limit dynamic range and sensitivity at no added value, because resolution is limited by seeing (air turbulences) and optics, rather than by pixel size. At the same time greater pixels could provide under-sampled images if optics is good and the mount perfectly tracks the stars and seeing is above average.

Read noise around 10e-RMS is well beyond the sky background noise in the case of long exposures, even if the very best narrow-band filters are used (no to mention standard RGB filters). Dark current below 0.1 e-/s/px at 0 °C allows very long exposures, providing the sensor is used in a camera allowing for proper cooling (like the G3-16200). Quantum efficiency reaching 60% surpasses the QE of very popular KAF-8300 CCD and is almost identical to the KAF-16803.

The G3 camera is an excellent camera chassis with very low noise electronics that allow the full performance of the sensor to be realised. The cooling performance of the standard version is 48°C below ambient ensuring very low dark current. This enhanced version of the camera has superior cooling which increases maximum cooling to 53°C below ambient. This 5°C increase reduces dark current by half and leads to improved camera performance in all enviroments.
