ASI432MM

Description

The ZWO ASI432MM is a monochrome planetary camera featuring Sony’s IMX432 global shutter CMOS sensor. Unlike the rolling shutters found in most astronomy cameras, the IMX432’s global shutter reads every pixel simultaneously — eliminating the geometric distortion that rolling shutters can introduce when capturing fast-moving targets or during periods of rapid atmospheric turbulence.

With 9.0 μm pixels in a 1608 x 1104 format (1/1.2″ sensor), the ASI432MM is optimized for high-speed planetary imaging at moderate focal lengths. The large pixel size delivers excellent sensitivity and full-well capacity, capturing more photons per pixel per frame. This is particularly advantageous for lucky imaging, where you need fast exposures to freeze seeing. The monochrome sensor captures roughly twice the signal of an equivalent colour sensor and allows you to use specific wavelength filters (R, G, B, IR, methane band) for maximum flexibility.

USB 3.0 connectivity supports high frame rates, and the built-in ST4 port provides autoguiding capability. The camera is compatible with all major capture platforms including FireCapture, SharpCap, and ASIAIR. Its compact body and 1.25″ nosepiece make it easy to integrate into any imaging train.

The ASI432MM is aimed at dedicated planetary imagers who want the advantages of global shutter and monochrome sensitivity. If you image Jupiter, Saturn, or Mars through filters and want distortion-free captures at high frame rates, this camera offers something that most CMOS cameras in this price range cannot: a true global shutter readout.
