The ZWO ASI533MC-Pro is a high-performance cooled color astronomy camera ideal for capturing deep-sky objects, as well as high-resolution images of the Moon, Sun, and planets. Its square-format sensor, advanced cooling system, and innovative design make it a versatile tool for astrophotographers of all levels.

Key Features

Square 1” Sony IMX533 Sensor
Equipped with a 9-megapixel back-illuminated CMOS sensor with 3008x3008 resolution and 3.76µm pixels, the camera is perfect for framing symmetric celestial objects like star clusters and nebulae.
Enhanced Image Quality
The back-illuminated design improves sensitivity and reduces noise, with a high quantum efficiency (QE) of 80% and low read noise of just 1.0e. The sensor’s 50,000e full well capacity ensures bright stars remain sharp without saturation.
Zero Amp Glow
Features advanced circuitry to completely eliminate amp glow, even during long exposures at high gain, resulting in cleaner, more accurate images.
Efficient TEC Cooling and Anti-Dew Heater
A two-stage TEC cooling system reduces sensor temperature by up to 35°C below ambient, minimizing noise. The heat generated by the cooler also prevents dew formation on the camera window.
Fast Data Transfer
Includes a 256MB DDR3 memory buffer for stable data transfer and reduced amp glow. The USB3.0 port supports fast data rates of 20 fps at full resolution.
Dynamic Range and Low-Noise Performance
Offers a dynamic range of up to 14 stops, with optimal performance at a gain setting of 100. This makes it well-suited for electronically assisted astronomy (EAA) and traditional astrophotography.

Compact and User-Friendly Design

The ASI533MC-Pro is ideal for both deep-sky imaging and solar-system photography. Its compact size, powerful cooling, and versatile square sensor make it a perfect choice for astrophotographers seeking excellent performance and reliability in a streamlined package.
