Product Description
ASI294 is the first camera in the world that equipped with SONY latest sensor IMX294CJK.
Sony IMX294CJK CMOS Sensor
Diagonal 21.63 mm (Type 4/3) Approx. 10.71M-Effective Pixel Color CMOS Image Sensor, This is the official description on Sony website. In our effort, we remolded it to make it Diagonal 23.2 mm (Type 4/3) Approx. 11.71M-Effective Pixel.
High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Astronomic Cameras and Industrial Applications
The “IMX294CJK” is the first in-house image sensor for astronomic cameras to adopt the Type 4/3 format, and realizes output of the number of pixels needed for 4K at 120 frame/s (in ADC 10-bit output mode, ASI294MC can run up to 25fps at 4k format base on USB3.0 bandwidth). In addition, use of a large-size pixel achieves SNR1s of 0.14 lx* which is very close to the value of ASI224(0.13 lx*).
Exceptional low-illumination performance
Exceptional low-illumination performance of SNR1s: 0.14 lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 µm. This makes the IMX294CJK ideal sensor for astronomic camera market applications which requires low-illumination performance.
14bit ADC & 13 stops DR
ASI294 have 14bit ADC and it can achieve 13 stops dynamic range which is even better than ASI1600.
HCG Mode
HCG mode will be on when gain is higher than 120(12db), read noise will drop below 2e but same dynamic range(13 stops).
Full well Capacity
63700e full well, which is 3 times than ASI1600’s capacity. Even bright stars won’t saturate under long exposure.
This camera can achieve higher SNR(signal to noise ratio) with just one single exposure.
USB 3.0 Port & ST4 Port
USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294MC to run at 16 fps (14bit, normal mode) or 19 fps (12bit, high speed mode) at full resolution(11.7Mega).
ST4 PortCan be used connect with auto guide port of mount, for guiding.
