The ZWO ASI 290MC is one of the newest members of ZWO’s camera range. Using a new Sony 2.1 mega pixel back-illuminated CMOS image sensor (IMX291), it demonstrates excellent sensitivity in the visible and near infrared wavelengths making it ideal for astronomy. In fact the ZWO ASI290MC is their best one shot colour planetary camera.

The small 2.9 µm pixels and back illuminated architecture provides enhanced picture quality in low light while still realizing full HD capture. The benefit for astronomy is more than 2x the sensitivity in visible-light and more than 3x the sensitivity in near infrared over existing Sony sensors (eg: IMX236LQJ).
