Simplified Setup, Powerful Imaging

ZWO’s integrated "Dual Sensor + ASIAIR" platform eliminates the complexity of traditional astrophotography setups. With the ASI585MC Air, you're ready to start imaging in minutes—no separate guiding or control units required.

Seamless Device Connectivity

Equipped with 4× USB 2.0 ports for accessories like focusers, filter wheels, or mounts; 2× 12V 10A ports to power your gear; and a USB-C port for high-speed data transfer. This camera serves as a control hub for your entire imaging setup—no tangled mess, no headaches.

Generous Internal Storage

With 256GB of built-in eMMC storage, the zwo 585 air camera offers fast, stable internal data saving for multiple sessions. It’s also tested for long-term reliability with over 300 performance benchmarks. If more space is needed, you can connect external USB storage up to 1TB.

STARVIS 2 CMOS Sensor with 4K Imaging

The ASI585MC Air features the Sony STARVIS 2 sensor, offering a higher dynamic range and improved low-light performance. This advanced tech delivers sharp, detailed 4K images—even under challenging night sky conditions, making this asi585mc camera ideal for faint deep-sky targets.

Zero Amp Glow for Cleaner Images

This camera eliminates amp glow at the hardware level, resulting in exceptionally clean dark frames - regardless of gain or exposure length.
The result: uncompromised image quality with no need for software-based amp glow correction.

Strong, Stable Wi-Fi with Dual-Band Antenna

The ASI585MC Air features a detachable external antenna supporting both 2.4GHz (longer range) and 5GHz (faster speed) networks. It maintains a strong, stable signal up to 20 metres in open conditions, ideal for remote or mobile setups.

Cross-Platform Compatibility

Beyond the ASIAIR mobile app, the ZWO ASI585MC Air also works with ZWO's ASIStudio software and third-party applications through ASCOM/Alpaca (ASCOM Platform v6.6 or later). This gives users flexibility to image via PC, tablet, or smartphone.

Total Control, Right From Your Phone

ZWO’s patented technologies allow you to run your entire imaging session directly from your smartphone. With support for OTA firmware updates, the ASI585MC Air constantly evolves—adding new features and improvements over time.

Real-Time Stacking & Instant Sharing

Live stacking is built into the zwo asi585mc air, allowing you to adjust exposure, contrast, and other image settings on the fly, then quickly share your results to social media or astronomy forums. It’s a streamlined workflow designed to keep you shooting and sharing with ease.

Built-in HCG Mode for Better Performance

The High Conversion Gain (HCG) mode automatically activates at gain 252, significantly lowering read noise to just 0.7e while preserving dynamic range near 12 bits. This makes it easier to capture both faint nebulosity and brighter stars in the same frame.

Peak Quantum Efficiency of 91%

Lab testing shows the ASI585MC Air achieves a peak QE of 91%, making it one of the most sensitive colour cameras in ZWO’s line-up—ideal for capturing detailed deep-sky images across a wide spectrum.

Two-Stage Cooled Sensor

Its dual-stage TEC cooling system can drop the sensor temperature by up to 30–35°C below ambient. This dramatically reduces thermal noise and dark current, especially during long exposures—perfect for high-contrast deep-space imaging.
