ZWO ASI 533MC Pro – High-Performance Astrophotography Camera

The ZWO ASI 533MC Pro is an advanced astrophotography camera featuring Sony’s latest 1-inch square IMX533 back-illuminated sensor. Designed for deep-sky imaging, the ASI533MC Pro offers superior image quality with zero amp glow, low read-out noise, and a two-stage TEC cooler for long-exposure shots.

Key Features of the ZWO ASI 533MC Pro

IMX533 1” Square Sensor: The ASI533MC Pro is equipped with a 9MP CMOS sensor that produces stunning, high-definition images with a 3.76µm pixel size. Capable of capturing 20 frames per second in 14-bit mode, the camera offers **low read-out noise** as low as 1.0e, making it perfect for astrophotography.

Sony IMX533 Back-Illuminated CMOS Sensor: The back-illuminated sensor technology improves light sensitivity and reduces noise, enhancing the quality of astrophotography images. It minimizes obstacles like metal wiring, allowing more light to hit each pixel. This ensures improved performance, especially during low-light imaging scenarios.

Zero Amp Glow for Long Exposures

Unlike traditional CMOS sensors, the ZWO ASI 533MC Pro features **zero amp glow circuitry**, eliminating the typical bright infrared glow seen in uncalibrated images. You can now capture long-exposure astrophotography without worrying about amp glow. See the comparison below:

TEC Cooling for Noise Reduction

The ZWO ASI 533MC Pro features an enhanced two-stage **TEC cooling system** that reduces thermal noise and maintains optimal sensor performance during long-exposure sessions. With up to **35°C cooling below ambient temperatures**, the TEC system ensures sharp, noise-free images even during extended astrophotography sessions.

Performance Comparison: ZWO ASI 533MC Pro  vs. ASI183MC Pro

The ZWO ASI 533MC Pro builds on the success of the ASI183MC Pro by offering even greater **noise reduction**, a higher **dynamic range**, and **zero amp glow**. The **3.76µm pixel size** allows for more detail in your images, while the **USB 3.0 interface** and **DDR3 memory buffer** ensure fast and stable data transfer during imaging.

Power Requirements

All **Pro cameras** (with coolers) must be connected to an external **11-15V power supply** for operation. Even if the cooler is not used, the power supply is necessary for the camera to be recognized. We recommend using a **12V DC power adapter** (5.5*2.1mm, centre pole positive) or a **lithium battery** for smooth performance. Power supplies outside this range may damage the camera.
