ZWO ASI 174 Mini Monochrome CMOS Telescope Guide Camera

The ASI174 Mini is a top notch monochrome guide camera, well suited to both planetary imaging 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; with a peak QE of 77%, a read noise of only 3.5e, a pixel array of 1936 x 1216, and a pixel size of only 5.86 micrometers, it qualifies as a powerhouse despite it's small size. It achieves all of this while presenting a small and slender profile, taking up a minimum of space in your imaging train. The interface for this camera is a Type C USB 2.0 port, similar to that found in several mobile phone types.
