Start your astrophotography journey with great convenience
The ASI585MM Air combines guiding, imaging, and smart control into one compact, lightweight device. Say goodbye to complex setups and enjoy a seamless, hassle-free astrophotography experience.

Imaging sensor
The main IMX585 sensor has a 1/1.2-inch format and 8.28 MP in total. The size is 11.2 mm in width x 6.3 mm in height and the diagonal is 13.2 mm. The small pixel size of 2.9 µm x 2.9 µm offers high resolution and a good full-well capacity of 38.7 ke.

Guiding sensor
The SC2210 sensor taken from the ASI220MM Mini camera features very high sensitivity. The QE peak value reaches 92% at 500 nm. The read noise is as low as 0.6 e. As the new generation of guide sensor, it has achieved great results in guiding, proved by hundreds of astrophotographers.

Effortlessly connect multiple devices: 4x USB2.0, 2 x DC 12 V 10 A, 1x USB Type-C
USB 2.0 ports for your focuser, filter wheel, and mount, DC 12 V 10 A input/output ports for reliable power, and USB Type-C port for fast file transfers to computer - you can focus on capturing stunning images without worrying about connectivity issues.

Shoot with confidence: ample storage and stability
With a massive 256 GB eMMC storage, the 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 1 TB external storage, giving you plenty of room for all your astrophotography needs.

Dive into the rich details of the celestial objects
The full-well capacity of this camera is 38.7 ke, making long exposure images less prone to overexposure. The good full-well capacity and high dynamic range make it possible to capture both bright and dark areas with amazing clarity and detail. Experience the wonderful details and colors (via RGB exposures) of objects like never before!

The HCG mode
The camera has a built-in HCG mode that can effectively reduce readout noise at high gain and maintain the same wide dynamic range that you would expect at low gain. When the gain is 200, the HCG mode will turn on automatically. This results in readout noise of just over 1 e-, while the dynamic range can still reach almost 12 f-stops.

Note: Previously, HCG mode switched on at a gain of 252. To switch on at a gain of 200, you must update ASIAIR or ASIStudio. After updating, you will need to re-shoot calibration frames to ensure proper stacking in post-processing.

Dual-band Wi-Fi for stable signal
Experience unparalleled connectivity with ZWO´s enhanced external dual-band antenna, supporting both 2.4G and 5G frequencies and offering stable and smooth usage within 20 meters.

Get full control of your entire rig at your fingertips
With the ASIAIR smart app, you can easily control guiding, imaging, your mount, and electronic focuser - all from your phone. It supports multiple imaging modes, making it easy for even beginners to quickly learn and capture professional-quality images.

Guiding
After connecting to the mount, guiding is realised via the built-in guiding sensor, the built-in ASIAir control and the imaging software, i.e. the ASIAIR app or ASIImg from the ASIStudio suite. An ST-4 autoguider cable to the mount is therefore just as unnecessary as a separate guiding camera.

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.

Go further with ZWO´s self-developed system
Powered by ZWO´s patented technologies, the system ensures stable astrophotography performance. Continuous App OTA updates keep your device up-to-date with the latest features, enhancing your user experience and expanding your capabilities.

Practical tip: Good storage is an important preventive measure against dew and also extends the service life:

After use, put the camera straight into a TS Protect Case and add some silica gel. During storage, the silica gel absorbs the moisture from the camera. At the same time, the penetration of moist room air is prevented. Dry storage can even partially regenerate the small desiccant tablets in cooled cameras. Your camera or accessories are always ready for you in optimum condition. You can find the silica gel and the case in our product recommendations.

The cameras are not airtight, so if the camera remains on the telescope, it is exposed to moisture. The small amount of desiccant in the camera can protect the sensor and the inside of the protective glass from moisture for the duration of the exposure, but not for days on end. Moisture problems can be the result. A simple trick is to stretch a plastic bag around the focuser to which the camera is attached so that no air can get in. Silica gel is placed in a small cloth bag inside the plastic bag. This will also create a "dry climate zone" for the camera on the telescope. This allows you to leave the camera on the telescope for a few days for an imaging session lasting several days.

In the medium and long term, however, this is no substitute for proper storage in an airtight case with silica gel.
