256G eMMC Storage： Ample Storage and Stability
With 256GB eMMC storage, the ASI585MC Air allows you to capture multiple targets with ease. Rigorously tested with over 300 benchmarks, it ensures system stability. Plus, the USB 2.0 ports support up to 1TB external storage, giving you plenty of room for all your astrophotography needs.
Starvis 2 4k Sensor
Image Sensor Technology Beyond the Human Eye’s Sensitivity
Equipped with the upgraded STARVIS 2 image sensor, supporting a higher dynamic range.
With this technology, the sensitivity and signal-to-noise ratio of the ASI585MC Air are greatly enhanced, delivering exceptional image quality.
No Amp Glow
The ASI585MC Air exhibits zero amp glow, which ensures extremely clean dark-field images. No matter how long the exposure and how high the gain value, you can easily capture high-quality astrophotographs.
300s exposure image
Note: It is implemented directly at the hardware level, it does not require software control.
Dual-Band Wi-Fi for Stable Signal
Experience unparalleled connectivity with our enhanced external dual-band antenna, supporting both 2.4G and 5G frequencies and offering stable and smooth usage within 20 meters.
Cross-Platform Device Control
ASI585MM Air can also wirelessly connect to ZWO’s proprietary PC control software, ASIStudio, and also other 3rd-party PC software. 3rd-party software can be controlled through ASCOM extended protocol Alpaca (requires ASCOM Platform version V6.6 or higher).
(Note: 2.4G has a longer transmission distance but slightly slower speed compared to 5G. The 20-meter range is based on multiple tests of the 2.4G frequency in open areas.)
Get Full Control of Your Entire Rig at Your Fingertips
The ASI585MM Air incorporates multiple ZWO patented technologies and allows you to shoot simply by connecting your phone. It supports App OTA updates, continuously improving the product features, making astrophotography easy and fun, while enriching the user experience.
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.
Low Read Noise, High Dynamic Range
The camera 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 252, 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.
Quantum Efficiency
After “ZWO Laboratory” calculation, the peak quantum efficiency of ASI585MC Air is 91%
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.

Built-in Filters
The ASI585MC Air camera features a UV-IR Cut filter in front of the sensor, serving as a protective window that blocks infrared light.
The ASI585MM Air camera is equipped with an AR (Anti-Reflective) coated protective window, which enhances light transmission and minimizes reflections.

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.
