Large format G4 CCD cameras
Moravian Instruments G4 CCD cameras are capable of using large CCD detectors with 37 × 37 mm area, which is 50% more than the area of a classical film frame. Precisely regulated cooling keeps the CCD at constant temperature, which allows high quality image calibration. The Moravian Instruments G4 Cameras can also be equipped with liquid-coolant heat exchanger to cool down the hot side of the Peltier TEC modules, beside the two magnetic levitating fans used in air cooled cameras. The G4 cameras are equipped with near-IR preflash electronics to cope with the Residual Bulk Image effect.

The used CCD detectors are equipped with so-called “anti-blooming gate” (ABG), which drains the over-abundant charge from saturated pixels. ABG ensures the round images of bright stars, without disruptive blooming spikes. This is particularly important for large format cameras, which often provide wide field of view. Moreover, compromising the linearity of the CCD by ABG is negligible and it has no effect on photometric or astrometric observations. G4 cameras are used for astronomical research and also considered to be the ultimate camera for astrophotography. |
