ASI294 is the first camera in the world equipped with SONY's latest sensor, the IMX294CJK.

ZWO has reworked Sony's sensor to provide a 23.2 mm diagonal (Type 4/3) with approximately 11.71M-Effective Pixel. 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.

ASI294 Pro camera includes one 256MB DDR3 memory buffer to help stabilize data transfer and prevent amp-glow issues caused by the slow speed data transfer of a USB2.0 Port. This DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

ASI294 have 14bit ADC and it can achieve 13 stops dynamic range which is even better than the ASI1600. This camera also boasts 63700e full-well depth, which is 3 times than the ASI1600’s capacity. Even bright stars won’t saturate under long exposure.

ASI294MC Pro has same mechanics as ASI1600 Pro. Four screws seal the chamber. This structure has been fully tested and it is very stable.

Even in high humidity environments, ASI294MC Pro will still works without dew problems.

IMX294 sensor is a BSI (back-illuminated type) sensor and has very high QE (we infer the QE peak is more than 75%).


USB 3.0 Port & USB 2.0 HUB

USB 3.0 port provides 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 or more 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.

Cooling System

ASI294 Pro has 2 stage TEC cooling system to enable very deep cooling (-35℃ below ambient). you need external power supply to power on the cooler. AC-DC power adapter is not included in this package, you can order from here.
