Guide Sensor

Start Your Astrophotography Journey with Great Convenience

The ZWO ASI585MM-AIR integrates imaging, guiding, and smart control, 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 10A, 1x USB Type-C

USB 2.0 ports for your focuser, filter wheel, and mount; DC 12V 10A 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.

Ample Storage, Explore Without Limits

With 256GB eMMC storage, the ZWO ASI585MM-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 ZWO ASI585MM-AIR are greatly enhanced, delivering exceptional image quality.

No Amp Glow

The ZWO ASI585MM-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.

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, the ZWO ASI533MM-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 ZWO 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.

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.

Low Read Noise, High Dynamic Range

The camera has a built-in HCG mode, which can effectively reduce readoutnoise at high gain and allow the camera to maintain the same high dynamicrange as it does at low gain. When the gain is 252, the HCG mode isautomatically turned on and the Dynamic range reaches a level close to 12 bit.The readout noise is as low as 0.7 e-.

Quantum Efficiency

After “ZWO Laboratory” calculation, the peak quantum efficiency of the ZWO ASI585MM-AIR is 91%.

Data source: This data is from ZWO Laboratory. The actual quantum efficiency peak value is subject to real-world data.

Image Circle Compatibility Reference

Please refer to the diagram below to understand how ASI585MM-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.
