ZWO ASI294MC Color

The ZWO ASI294MC Color is a versatile color camera with the Sony IMX294 CMOS sensor - ideal for astrophotography without cooling. Thanks to its high sensitivity, large full well capacity and high resolution, this camera is well suited for deep-sky objects as well as the moon and planets.

The ZWO ASI294MC Color is the first astro camera to feature the Sony IMX294CJK sensor. This back-illuminated sensor delivers razor-sharp images with a quantum efficiency of over 75%. Even without active cooling, you can take beautiful pictures of nebulae and galaxies with short exposures and stacking.
