Sony IMX294CJK uses larger-sized pixels and it achieves SNR1s of 0.14 lx: this makes the ASI294MC-PRO camera ideal for astronomy applications that require low-illumination performance. The ASI294MC-PRO has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. This is an excellent characteristic for deep sky imaging, which is inherently high dynamic range. At 13 stops, the ASI294MC-PRO has even more dynamic range than the ASI1600.
The ASI294MC-PRO has a 2-stage TEC cooling system that enables deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera. HCG (high conversion gain) mode, which reduces read noise to even lower levels at higher gain without loss to dynamic range, is automatically enabled when the gain setting is 120 or higher. Read noise will drop under 2e-, while dynamic range will remain at 13 stops.
ASI294MC-PRO camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port. USB 3.0 port provides 5Gb bandwidth to let ASI294MC-PRO run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (11.7 megapixels).
