ZWO ASI290MM Mini

For those seeking the utmost accuracy in their astrophotographic endeavors, look no further than the ASI290MM Mini camera. Designed specifically for guiding purposes, this remarkable device boasts unparalleled precision. Its employment of a light-sensitive element with a single pixel size measuring 2.9 x 2.9 µm grants it the finest angular resolution among all ZWO Mini models. In practical terms, this means that the ASI290MM Mini offers a 30% improvement in guidance accuracy compared to its counterpart, the ASI120MM Mini.

At the heart of this camera lies the monochrome Sony IMX290LQR sensor, a 2.1 MP marvel. Renowned for its low power consumption and minimal heat dissipation, this sensor maintains exceptional performance even with passive cooling. The readout noise remains at an impressive level, not exceeding 1 e. Furthermore, the sensor is safeguarded by a swift anti-reflective (AR) coating, enabling captivating results when used in conjunction with the IR-Pass filter.

Enclosed within a lightweight and compact aluminum casing, elegantly finished in ZWO's signature red color, the ASI290MM Mini camera exudes both functionality and style.
