    ZWO ASI290MM Mini Monochrome Imaging Camera


    One of ZWO's two initial Mini Cameras, the ASI290 Mini features a Sony IMX290/IMX291 1/3" sensor (5.6 mm x 3.2 mm). Pixel size is 2.9 µm x 2.9 µm with a pixel array of 1936 x 1096. This camera offers 12-Bit ADC and a QE peak of more than 80%.

    Astrophotography Performance

    For planetary imaging as well as guiding, the ZWO ASI290 Mini Camera is a fine performer. Low read noise, high dynamic range, a QE peak over 80%, and AR protective window, are among its highlights.

    ASI290 Mini vs. ASI290MM

    The ASI290 Mini is lighter and has a smaller outlook than the ASI174MM. It is also capable of reaching focus at the same position as the eyepiece. See images for a detailed comparison.

    USB 2.0 and ST4 Ports

    ZWO Mini cameras feature one USB2.0 type C port. Type C ports are optimally suited for mobile phones as the positive and negative sides of the adapter are not important. The ST4 port connects the ASI290 Mini directly to a mount's autoguiding port.

    High Sensitivity

    When designing the ASI290 Mini, ZWO considered sensitivity to be of utmost importance. Being able to look for a guide star is essential. So when they were first starting out, ZWO thought to use a monochrome sensor to design their guide camera since mono sensors have much higher sensitivity when compared with color sensors. ZWO ultimately decided to go with the 290 and 174 monochrome sensors which have a QE peak of approximately 80%, detecting a larger number of stars in view. In addition, guiding shortens exposure time.

    Precise Guiding

    Made for precise guiding, the ASI290 Mini contanis 2.9 µm pixels for a higher arcsec per pixel than either the 224 or 120 series cameras. This means the ASI290 Mini can detect even more negligible star movement in the same guide scope. This camera can enhance guiding precision over the 120 mm by about 30%.

    ASIair Pro Camera Control (sold separately)

    There is a wireless camera control solution available for this camera, and it's called the ZWO ASIair Pro. This small wireless module allows you to focus, take images, make adjustments with your smartphone or tablet, and even do plate solving and computerized mount control with the built-in SkySafari bridge. If you'd like to add an ASIair Pro to your camera order, you can find it in the suggested accessories section.
