The ZWO ASI533MM Pro Cooled Monochrome Astronomy CMOS Camera is a great monochrome camera for deep space astrophotography.

The ZWO ASI533MM Pro Monochrome Camera is an excellent option for astrophotographers seeking high-definition imaging with low read noise. As a step up from the ASI183 series, it retains key features like high quantum efficiency and great frame rates while introducing significant design improvements.

Camera Performance

Featuring a Sony IMX533 back-illuminated 1-inch square sensor, the camera boasts 3.76μm pixels, 9 million effective pixels, and supports a 20fps frame rate with 14-bit output. These features make the ASI533MM Pro an outstanding choice for beginners and enthusiasts focusing on deep space astrophotography.

Equipped with 2-stage TEC cooling, the ASI533MM Pro reduces the sensor temperature by up to 35°C below ambient, enhancing the signal-to-noise ratio and minimising dark current. Its zero-glow circuitry eliminates amp glow, ensuring clean images even during long exposures or high-gain settings. With a remarkably low read noise of just 1.0e and a quantum efficiency exceeding 91%, this camera delivers exceptional performance.
