Meet the ASI4400MC Pro: Dedicated Deep Sky Imaging Camera
The ASI4400MC Pro is ZWOs newest addition to their top-of-the-line cooled One-Shot Color (OSC) cameras.Allowing you to capture full-color deep sky images without needing separate narrowband or color filters or complex post-processing. With improved electronics and a sleek new matte finish. This full-frame, cooled CMOS camera is built around Sony’s powerful IMX366 back-illuminated sensor, offering 44 megapixels of resolution, incredible sensitivity, and exceptionally low noise.
ZWO has refined the ASI4400MC Pro with a new motherboard that lowers readout noise and increases frame rate, making it even more effective for capturing galaxies, nebulae, and star clusters in stunning detail. Whether you’re upgrading from an older camera or starting your journey into full-frame astrophotography, the ASI4400MC Pro is perfect for beginners who want simplicity, or experienced imagers who want to get high-quality images faster!
Unmissable Advantages
Key Features of the ASI4400MC Pro
Why Choose the ASI4400MC Pro
Full-frame Imaging Power
At the heart of the ASI4400MC Pro is Sony’s IMX366 sensor, a full-frame chip measuring 36x24 mm with a 43.3 mm diagonal. With a resolution of 8192x5460and small 4.4 µm pixels.
Zero Amp Glow
The true zero amp glow design guarantees clean, artifact-free images, even during long exposures at high gain. This means you can capture faint deep-sky details without unwanted bright spots or glow in the corners, giving you sharper, more professional results.
Advanced Cooling
A two-stage TEC cooling system allows the sensor to cool down up to 35°C below ambient temperature. This drastically reduces dark current noise. At 0°C, dark current noise is only 0.0017e/s/pix, effectively negligible, even in 5-minute exposures.

Tiltable Sensor Design
The ASI4400MC Pro includes a tiltable sensor mount with push-pull screw adjustments, allowing you to fine-tune tilt and achieve a perfectly flat imaging field across your entire frame.
Stable Data Transfer
With USB 3.0 connectivity and a 512MB DDR3 buffer, this camera ensures smooth, stable data transmission with no dropped frames, even during long exposures.
Built-in Anti-dew Heater
ZWO’s built-in polyimide anti-dew heater keeps the protective window clear, preventing condensation and ensuring you don’t lose imaging time. It fully covers the window and heats it evenly, eliminating dew problems during your imaging sessions.
Efficient Cooling
The ASI4400MC Pro uses a powerful two-stage TEC cooling system capable of lowering the CMOS sensor temperature by 30°C to 35°C below ambient. This deep cooling dramatically reduces dark current and thermal noise, keeping your images clean and smooth - even during long exposures that last several minutes. The result is higher signal-to-noise ratio and improved image quality in every frame.
Note: Cooling performance varies with ambient temperature. The lower the ambient temperature, the smaller the achievable differential. Results are based on tests at 30°C ambient. Operation below -20°C is not recommended.
Full-Frame for a wider field of view
The ASI4400MC Pro uses a full-frame, back-illuminated sensor measuring 36x24 mm with a 43.3 mm diagonal. With 44 megapixels and 4.4 μm pixels, it delivers incredible resolution and light sensitivity in every shot. The full-frame format lets you capture the entire field your optics can deliver - no cropping, no lost edges - perfect for wide-field targets and large deep-sky objects. Each pixel supports a full-well capacity of 74,600 electrons, providing exceptional dynamic range. Bright stars retain their natural color and detail, while faint nebula structures and galaxy arms remain beautifully visible. The result is cleaner, more balanced images with outstanding tonal depth across the frame.
High Dynamic Range
The ASI4400MC Pro features a 14-bit analog-to-digital converter (ADC) that delivers a dynamic range of over 13 stops. This wide range allows a single exposure to capture both bright highlights and faint shadow details without clipping. Whether you’re imaging bright stars, nebula cores, or the delicate wisps of distant galaxies, more tonal information is preserved for smoother gradients and richer color depth. The result is a natural, well-balanced image straight out of the camera, with plenty of flexibility for post-processing and fine-tuning.
Wavelength Charts
High Quantum Efficiency
The IMX366 sensor achieves a peak QE of 80%, maximizing sensitivity and making the most of every photon collected by your telescope.
Ultra-Low Dark Current
Thanks to the ASI4400MC Pro’s advanced cooling system, thermal noise remains extremely low even during long exposures lasting several minutes. Dark current is a small electrical signal created by heat inside the sensor rather than by incoming light. By keeping the sensor temperature low, the camera minimizes this effect, producing cleaner, higher quality images with smoother backgrounds.
Low Readout Noise, High Dynamic Range
The ASI4400MC Pro offers a dynamic range of up to 13 stops, allowing it to capture both bright highlights and faint shadow details in a single exposure. This wide range is key to achieving high dynamic range (HDR) performance, preserving fine tonal transitions and subtle color detail in deep-sky images. When the gain setting reaches 136, the camera automatically activates HCG (High Conversion Gain) mode, which greatly reduces read noise while maintaining full dynamic range. This means you can increase sensitivity for faint targets without adding unwanted gain noise, making it easier to capture clean, detailed images under a variety of conditions.
UV-IR Cut Filter
The ASI4400MC Pro is equipped with a UV-IR cut filter mounted in front of the sensor. This protective filter blocks unwanted ultraviolet and infrared light that can cause star bloat and color distortion, allowing only visible wavelengths to reach the sensor. By filtering out these non-visible wavelengths, the camera produces sharper stars, more accurate colors, and overall improved image quality in astrophotography.
Full-Frame Products Comparison
The ASI4400MC Pro is the latest addition to ZWO’s full-frame deep-sky camera lineup. Positioned between the ASI6200MC Pro and the ASI2400MC Pro, the ASI4400MC Pro strikes the perfect balance between image quality and efficiency, giving users a versatile option within the full-frame lineup.
