ZWO ASI294MC Pro Cooled Color CMOS Astrophotography Camera

Perfect for deep space astrophotography and planetary imaging!

11 MP micro four-thirds sensor.

High conversion gain boosts sensitivity without losing dynamic range.

Thermoelectric cooling down to minus 35 degrees Celsius below ambient.

Shoots 4k video at 24 FPS and 320 x 240 at 179.3 FPS.


Versatile | Compact | Exceptional Image Quality

The ASI294MC Pro is a micro four-thirds camera packed with features that help you produce world-class images.



The first image sensor to take on the four-thirds format providing the necessary amount of pixels for better images.

Low-illumination performance from its large optical system makes it ideal for astrophotography.

Minimize your camera's amp-glow with improved and reliable data transfer using the DDR memory buffer.

Achieve a high signal-to-noise ratio with just one single exposure!

With exceptional noise reduction technology and video capabilities, the 294 Pro is ideal for photographing: Nebulae, galaxies, planets, solar images,  lunar images, and more.

Sony IMX294CJK HCG Mode

Reduce your camera's read noise levels to lower settings at higher gain without loss to the dynamic range when in HCG Mode. Its automatically enabled when the gain setting is 120 or higher. See your camera's read noise drop under 2 electrons, while the dynamic range will remain at 13 stops!

ZWO ASI Short Back Focus 


Most Adaptable Camera Body

Like most ZWO cooled cameras, this 294 Pro body has a short back focus of 6.5 mm. This makes it very easy to adapt to almost any telescope system. Especially telescopes or reducers where back focus is very scarce.
