    Optimum Design

    Encamped in a vibrant, metallic red aluminum housing and with both a USB and ST4 autoguider port, the ZWO ASI174MM is versatile and fast. 

    Prioritized Mechanics

    Sony IMX174 CMOS Sensor 

    Bad vision, wind, or movement can alter the image if the readout speed is not quick enough (< 30fps). The Sony IMX174 CMOS sensor assures images of moving objects avoid focal plane distortion, something crucial during solar and lunar imaging.

    Fast and lightweight

    I use this with a Lunt LS80. The entire sun fits easily into the field of view, but significantly undersamples the scope with the rather large pixels. The big advantage for daytime astrophotography is the global shutter feature.
