Start Your Astrophotography Journey with Great Convenience
Featuring ZWO's self-developed "Dual Sensor + ASIAir" integration technology. Say goodbye to complex setups and enjoy a seamless, hassle-free astrophotography experience.
Effortlessly Connect Mutiple Devices
4x USB 2.0, 2x DC12V 3A, 1x USB Type-C
USB 2.0 ports for your focuser, filter wheel, and mount; DC 12V 3A input/output ports for reliable power; USB Type-C port for fast file transfers—you can focus on capturing stunning images without worrying about connectivity issues.
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 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
Except from ASIAIR App, ASI2600MC 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 Fully Control of Your Entire Rig at Your Fingertips
The ASI585MC 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.
QE
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.
Cooling System
Thanks to the two-stage TEC cooling, ASI585MC Air can lower the CMOS sensor temperature to 30-35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
