The first astronomy camera series equipped with SONY's new IMX294CJK sensor.
The ZWO ASI1294MC features Sony's remarkable IMG294CJK 4/3 CMOS sensor with a massive 4144x2822 resolution! That's over 11 megapixels!
- Sony IMX294 4/3 CMOS Sensor
- Extremely low read noise - 1.2e @30db gain
- 14Bit ADC - provides real 14bit dynamic range
- Electronic shutter - no issues with vibrations sometimes found in mechanical shutters
- USB3.0 Port (back compatible with USB2.0) - 16fps@4144×2822
- AR coated protective window - all light can pass
- Compatible with Windows / Mac OS / Linux
23.2mm diagona,l approximately 11.7 megapixels.
Back illuminated highly sensitive 4.63μm pixels.
The 'IMX294CJK' is the first image sensor for astronomy cameras to adopt the 4/3 format and achieves the number of pixels required 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, the large-size pixels achieve SNR1s of 0.14 lx*, which is very close to ZWO's ASI224 (0.13 lx*).
DDR Memory Buffer
ZWO Pro cameras feature a 256MB DDR3 memory buffer to help maintain data transfer stability and reduce amp-glow issues caused by the slower data transfer speed when using a USB2.0 port.
All ZWO cameras include a 2-year warranty.
Camera Field of View Simulator
Exceptional low-illumination performance of SNR1s: 0.14 lx is achieved using a large-size optical system and by expanding the area per pixel to 4.63 µm. This makes the IMX294CJK sensor an excellent choice for astrophotography which requires high performance in low light.
14bit ADC & 13 stops DR
14bit ADC can achieve 13 stops dynamic range, which is even better than ASI1600.
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 is 3 times greater than the ASI1600’s capacity. Even bright stars won’t saturate under long exposure.
Can achieve higher SNR (signal to noise ratio) with just one single exposure.
ZWO's ASI294MC Pro has the same mechanics as their highly regarded ASI1600 Pro. Four screws seal the sensor chamber.
Even when used in higher humidity the ASI294MC Pro will will work fine, without dew problems.
IMX294 sensor is a BSI (back-illuminated type) sensor so has very high QE (ZWO measure the QE peak higher than 75%).
The dark current of the ASI294 is slightly higher than the ASI1600, based on ZWO test results.

ASI294MC Pro Dark Frame
USB 3.0 Port: Provides 5Gb bandwidth making it possible for the ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (11.7Mega).
Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.
Using a battery with 9-15V is also suitable for the cooler power supply.
USB 2.0 HUB: Can connect with various accessories such as filter wheel, guide camera and electronic focuser, for easier cable management. The USB Hub draws power from an external power supply if you have one connected. Two short 0.5m USB2.0 cables are included.
The ASI294 Pro has a 2-stage TEC cooling system that enables deep cooling (35°C-40°C below ambient). The cooler requires an external power supply - not included with the camera.
