ZWO ASI294MC Colour USB Camera

SKU: ASI294MC Categories: , ,

The ASI 294 MC Colour USB Camera offers exceptional low-illumination performance.

A 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 sensor for astronomic camera market applications which requires low-illumination performance.

ASI294 has a 14bit ADC and can achieve 13 stops of dynamic range which is even better than the ASI160.

It is not recommended for primarily deep space photography, AOC suggest a fan cooled model for all deep space object long exposure photography.
