Quick Guide
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 ASI585MM 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 ASI585MM 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 ASI585MM 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 ASI585MM 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 ASI585MM 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.

Q1. What is the ZWO ASI585MM Air used for?
The ZWO ASI585MM Air is a compact, all-in-one astrophotography camera designed for deep-sky imaging, planetary capture, and live stacking. It combines a high-performance imaging sensor, integrated guide sensor, and a built-in ASIAIR controller, streamlining the imaging process for wireless control through your smartphone or PC.
Q2. What makes the ASI585MM Air different from other ZWO cameras?
Unlike the standard ASI585MM or ZWO ASI585 Pro models, the 585MM air integrates guiding, imaging, and system control into one device. It includes 256GB onboard storage, dual-band Wi-Fi, Bluetooth, and TEC cooling, removing the need for a separate guide camera, control box, or laptop in the field.
Q3. How do I calculate backfocus with the ASI585MM Air when using a ZWO filter wheel?
The ZWO ASI585MM Air has a native 17.5mm backfocus. ZWO filter wheels (e.g., 5-position 1.25"/36mm) add about 20–21mm. Add a 16.5mm spacer or adapter to reach the total required 55mm optical backfocus. This configuration is ideal for use with flatteners and reducers that require this spacing.
Q4. What is the backfocus setup when using a ZWO OAG with the ASI585MM Air?
When using the ASI585MM Air with a ZWO OAG, account for the OAG's 16.5mm backfocus. A typical imaging train would be:
17.5mm (camera) + 16.5mm (OAG) + 21mm (spacer or filter wheel) = 55mm total.
Ensure the OAG prism is correctly aligned with the main sensor for optimal guiding performance.
Q5. Do filters affect the backfocus of the ZWO ASI585MM Air?
Yes, filters shift the focal point slightly. As a general rule, subtract 1/3 of the filter thickness from your backfocus. For example, a 2mm filter requires reducing backfocus by ~0.66mm. ZWO's 55mm recommendation already factors in this adjustment for standard 2mm filters in filter wheels or drawers.
Q6. What mounts and accessories can I connect to the ASI585MC Air?
The ZWO ASI585MM air is compatible with most GoTo equatorial mounts using USB or serial interfaces. It features 4× USB 2.0 ports, 2× 12V DC outputs, and 1× USB-C port, allowing connection to mounts, filter wheels (EFW), focusers (EAF), and other ZWO accessories.
Q7.Does the ASI585MM Air need a separate guide scope?
No, the ZWO ASI585MM Air includes a built-in guide sensor, eliminating the need for a separate guide scope or guide camera. This makes the ZWO 585 air camera an efficient and portable solution, especially for mobile setups.
Q8. What software is compatible with the ASI585MM Air?
The ASI585MM Air works seamlessly with the ASIAIR mobile app for full wireless control. It also supports ZWO ASIStudio on Windows/macOS and works with third-party programs like NINA, SharpCap, APT, and Sequence Generator Pro via ASCOM/Alpaca (v6.6+) drivers. Be sure to keep your software up to date for full compatibility with the 585MM Air.
Q9. Is the ZWO ASI585MM Air compatible with ASIAIR?
Yes. The ASI585MM Air is based on ASIAIR technology, meaning full compatibility is built in. You can control cooling, gain, exposure, filters (if EFW is connected), and guiding directly from the ASIAIR mobile app, with support for OTA firmware updates.
Q10. Can I share images directly from the ASI585MM Air?
Yes, the ZWO 585MM air supports live stacking with real-time preview, and lets you adjust image parameters such as brightness, contrast, and exposure on the fly. You can share your processed images directly to social media or cloud platforms—no laptop required.
