A Convenient Solution for Astrophotography
Connect Multiple Devices
With 4 USB 2.0 ports for accessories like your focuser, filter wheel, and mount, plus two DC 12V 10A input/output ports for dependable power distribution, this system keeps your setup running smoothly. A USB Type-C port provides fast file transfers and streamlined connectivity, allowing you to concentrate on capturing stunning images instead of managing cables.
2-In-1 Imaging Solution
The ASI585MM Air packs two specialized sensors in one compact body - a high-resolution IMX585 main sensor for deep-sky imaging and an SC2210 guide sensor for real-time tracking. The guide sensor’s exceptional sensitivity (QE up to 92%) ensures accurate guiding without needing a separate off-axis guider
Dual-Band Wi-Fi
Beyond the ASIAIR app, the ASI585MM Air can also connect wirelessly to ZWO’s ASIStudio software as well as compatible third-party PC applications. These programs can interface with the device through the ASCOM Alpaca protocol (ASCOM Platform 6.6 or later), offering flexible control options for a wide range of setups.
All-in-One Control with Built-In ASIAIR
The ASI585MM Air doesn’t just capture incredible images - it also runs your entire imaging session, thanks to a fully integrated ASIAIR smart computer built into the camera body. This onboard system replaces the need for a separate ASIAIR controller or external mini PC, streamlining your gear and minimizing cable clutter.
With the ASIAIR built in, you can wirelessly control every aspect of your setup from your tablet or smartphone using the ASIAIR app. The ASIAIR software supports key imaging modes such as:
- Preview Mode for quick framing and focus
- Autorun Mode for capturing calibrated image sequences using flats, darks, and bias frames
- Live Stacking Mode for real-time stacked previews of deep-sky targets
- Plan Mode for scheduling mosaics or multi-target sessions in a single night.
File management is handled automatically on the 256GB of fast onboard eMMC storage, with support for FITS, RAW, and JPEG formats.
ASI585MM Guide Sensor
This camera includes a built-in guiding sensor - the SC2210 mono CMOS, that was originally used in the ASI220MM Mini. It’s exceptionally sensitive, with a peak quantum efficiency of 92% at 500 nm and a read noise as low as 0.6 e, per ZWO. That means you get highly accurate guide star tracking without needing an external guide camera, making your setup cleaner, simpler, and more reliable for long-exposure astrophotography.
Easier Post-Processing with Zero Amp Glow
The ZWO ASI585MM Air eliminates amp glow - a common issue in older CMOS and CCD sensors where stray infrared light would create unwanted artifacts in your images. With advanced engineering and modern sensor design, including back-illuminated (BSI) architecture, onboard DDR4 RAM, and high-speed readout, the ASI585MMC Air delivers clean, high-quality data right out of the box. No extra processing tricks needed - just reliable, low-noise performance every time.
Low Noise Readout
The ASI585MM has a built-in HCG mode, which can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 200, the HCG mode is automatically turned on and the Dynamic range reaches a level close to 12bit. The readout noise is as low as 0.7e.
Built-in Filters
The ASI585MM Air camera features an AR (Anti-Reflective) coated protective window, which enhances light transmission and minimizes reflections.
Instant Post-Processing and Sharing
Live stack is supported during your imaging session. You may also make adjustments to brightness, contrast and others on the final image. Instantly share your masterpieces on social media platforms and astronomy communities, making your work stand out.
Dark Current Vs Temperature
The unique dark current suppression technology can further reduce dark current noise. At a cooling temperature of 0°C, the dark current noise is only 0.00845e/s/pix. This means a 300s exposure will only cause a dark current noise of 2.5 e/pix, which is completely negligible!
High Quantum Efficiency (QE)
After "ZWO Laboratory" calculation, the peak quantum efficiency of ASI585MM Air is 91%. Higher QE means the sensor captures more of the faint light from deep-sky objects, resulting in cleaner, brighter images with shorter exposure times.
*Data source: This data is from ZWO Laboratory. The actual quantum efficiency peak value is subject to real-world data.
Efficient Cooling, Superior Image Quality
The two-stage TEC cooling system lowers the CMOS sensor temperature by 30°C–35°C below ambient, effectively reducing dark current generation. Even during long exposures of several hundred seconds, noise remains minimal.
Note: The lower the ambient temperature, the smaller the cooling differential.
*Based on tests at 30°C ambient temperature. Cooling efficiency decreases as ambient temperature drops, and operation below –20°C is not recommended.
Image Circle Compatibility Reference
Please refer to the diagram below to understand how ASI585MC/MM Air cameras match with various telescope image circles. ZWO Air cameras are compatible with telescopes that support APS-C or larger image formats.
Note: When using a telescope with an APS-C image circle, you may notice slight distortion in the guide star. If you’re looking for more accurate and stable guiding performance, we recommend using a telescope with a full-frame or larger image circle.
