The ASI294 is the first camera in the world equipped with the latest Sony sensor IMX294CJK. Sony 10.71M-Effective Pixel Color CMOS Image Sensor (official description from Sony site), with a diagonal of 21.63mm (4/3 format). ZWO has refined the sensor and remolded it to increase the diagonal to 23.2mm with approximately 11.71M-Effective pixels (4/3 format). High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Astronomic Cameras and Industrial Applications The IMX294CJK sensor is the first in-house image sensor for astronomic cameras to adopt the 4/3 format, and provides the necessary number of pixels for true 4k output at 120 frames per second (w/ ADC 10-bit output mode, the ASI294MC can run up to 25fps at 4k format when used with USB 3.0). In addition, the use of larger-sized pixels achieves SNR1s (link this to Sony¡¯s page on SNR1s, so people know what it means) of 0.14 lx* which is very close to the value of the ASI224 (0.13 lx*). Exceptional low-illumination performance Exceptional low-illumination performance of SNR: 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. DDR Memory Buffer The 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. DDR memory buffer is the main difference between ASI ¡°Cool¡± and ¡°Pro¡± cameras. 14bit ADC w/ 13 stops DR The ASI294 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 ASI294 has even more dynamic range than the ASI1600. HCG Mode 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 to under 2e-, while dynamic range will remain at 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. Reliable Mechanics ASI294MC Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable. Even when used in higher humidity environments, ASI294MC Pro will still works fine without dew problems. High QE The IMX294 sensor is a BSI (backside illuminated type) sensor, which has very high QE (quantum efficiency, which we estimate is over 75% peak). Dark Current The dark current of the ASI294 is slightly higher than the ASI1600, based on our test results. Dark frame sample @ Highest dynamic range settings, 300s, -10°C, bin1. USB 3.0 Port & USB2.0 HUB USB 3.0 Port: 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). 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, so you can better manage your cables. The ASI294 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one. Cooling System 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, which is not included with the camera. You may order a suitable power supply from . Connecting Drawing 1. M43-T2 adapter (optional) 2.
