ZWO ASI4400MC Pro Full-Frame Cooled Colour Astronomy Camera

The ZWO ASI4400MC Pro is a premium full-frame cooled colour astronomy camera designed for advanced deep-sky astrophotography. Featuring a 44MP back-illuminated CMOS sensor, advanced TEC cooling, Glow Suppression technology, and High Conversion Gain (HCG), it delivers exceptional image quality for demanding imaging applications.

44MP Full-Frame Sensor

The 36 × 24mm back-illuminated CMOS sensor features 44 megapixels with 4.4μm pixels and a 43.3mm diagonal, providing expansive field coverage and outstanding image detail for full-frame astrophotography.

High Dynamic Range Performance

A 14-bit ADC delivers over 13 stops of dynamic range, preserving bright highlights, faint nebulosity, and subtle colour transitions within a single exposure.

High Conversion Gain Technology

At gain 136, High Conversion Gain (HCG) mode automatically activates, significantly reducing read noise while maintaining the camera's full dynamic range.

Advanced Dual-Stage TEC Cooling

The two-stage TEC cooling system lowers the sensor temperature by up to 35°C below ambient, reducing thermal noise and dark current for cleaner long-exposure images.

Hardware Glow Suppression

ZWO's proprietary Glow Suppression technology minimises sensor glow at the hardware level, producing cleaner images with reduced calibration requirements.

USB 3.0 with 512MB DDR3 Buffer

High-speed USB 3.0 connectivity combined with an onboard 512MB DDR3 memory buffer provides stable image transfer and fast download performance.

Integrated Anti-Dew Heater

A built-in polyimide heater prevents condensation on the protective window and can be disabled via software when conditions permit.

Sensor Tilt Adjustment

Integrated push-pull tilt adjustment screws allow precise sensor alignment for improved edge-to-edge star sharpness across the imaging field.

UV-IR Cut Filter

The factory-installed UV-IR cut filter blocks unwanted ultraviolet and infrared light, improving star sharpness, colour accuracy, and overall image quality.

Lightweight All-Metal Construction

Weighing approximately 700g, the ASI4400MC Pro features a durable all-metal body with efficient cooling vents, integrated fan cooling, and convenient USB and DC connections.

Ideal For

Full-frame astrophotography, wide-field deep-sky imaging, nebulae, galaxies, long-exposure imaging, and professional astronomy applications.
