ASI294MC Pro is the first camera in the world that equip with SONY latest sensor IMX294CJK.
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 Camera 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 from 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 for astronomic camera market applications that require low-illumination performance.
14bit ADC & 13 stops DR
ASI294 has 14bit ADC and it can achieve 13 stops dynamic range which is a little better than ASI1600.
HCG mode will be on when gain is higher than 120, read noise drops below 2e but same dynamic range(13 stops).
Full well Capacity
63700e full well, which is 3 times than ASI1600’s capacity. even a bright stars won’t saturate under long exposure.
This camera can achieve higher SNR(signal to noise ratio) with just one single exposure.
256MB DDRIII memory buffer helps data transfer more stable and no amp-glow issue which is caused by the slow speed data transfer during reading out when connect with USB2.0 Port.
USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: can provide 5Gb bandwidth to make it possible for ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(11.7Mega).
We recommends 12V at 3A~5A DC adapter for cooler power supply(2.1*5.5, center positive).
Battery from 9-15V is also suitable for cooling power supply.
USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cable better with USB2.0 hub. There are 2 short 0.5m USB2.0 cables coming with ASI294 Pro. the power of hub source from external power supply if you connect it.
ASI294MC Pro has same mechanics as ASI1600 Pro. There are 4 screws seal the chamber. This structure has been fully tested and it is very stable.
Even with high humidity eviroment, ASI294MC Pro will still works fine without dew problems.
IMX294 sensor is a BSI(back-illuminated type) sensor and has very high QE(we suppose the QE peak is better than 75%)
The dark current of 294 is a little bit higher than 1600 from out test result.
ASI294 VS ASI1600
Let’s see this table to compare the difference between 294 and 1600 camera:
