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


ZWO has implemented this sensor with a diagonal of 23.2 mm (Type 4/3) and produces 11.71 megapixel images.


High-Sensitivity Type 4/3 CMOS Image Sensor, Supporting 4K for Astronomic Camera Applications

The IMX294CJK sensor is the first in-house image sensor for astronomic cameras to adopt the Type 4/3 format, and provides the resolution needed for 4K at 120 frame/s (in ADC 10-bit output mode, the ASI294MC can run up to 25fps at 4k format base on USB 3.0 bandwidth).

Exceptional low-illumination performance

Exceptional low-illumination performance (SNR of 0.14 lx) is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 um. This makes the IMX294CJK an ideal sensor for astronomic applications requiring low-illumination performance.

14bit ADC & 13 stops DR

The ASI294 has a 14bit ADC and can achieve 13 stops dynamic range which is better than the performance of the ASI1600.

HCG Mode

The HCG mode will be enabled when gain is higher than 120 (12db) - the read noise will drop below 2e but keep the same dynamic range (13 stops).

Full well Capacity

This camera features a 63700e full well, which is 3 times the ASI1600's capacity. Even bright stars won't saturate under long exposure.

High QE

The IMX294 sensor is a BSI(back-illuminated type) sensor and has a very high QE (over than 75%).



USB 3.0 Port & ST4 Port


USB 3.0 Port: Provides 5Gb bandwidth to make it possible for the ASI294MC to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode)  at full resolution(11.7 Megapixels).

ST4 Port: Connect to your mounts auto guide port
