Product Details

  • A Go-To for Guiding and More

    The ZWO ASI290MM Mini is a top-notch monochrome guide camera, well suited for both planetary astrophotography and acting as a guider to amplify the usefulness of other astronomy instruments. Despite being qualified as a 'miniature' camera, it still operates at a high level of performance.

    A Powerhouse in a Small Package

    With a peak QE over 80%, a read noise of only 1.0 e, a pixel array of 1936 x 1096, and a pixel size of only 2.9 micrometers, it qualifies as a powerhouse despite its small size. It achieves all of this while presenting a small and slender profile, taking up a minimum of space in your imaging train.
