No Amp Glow

The ASI585MC/MM 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, 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.)

Powered by ZWO’s patented technologies, featuring smartphone connectivity and OTA upgrades for a seamless astrophotography experience.
Connect, capture, and upgrade effortlessly — astrophotography made smart and fun.

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 200, the HCG mode isautomatically turned on and the Dynamic range reaches a level close to 12bit.The readout noise is as low as 0.7e.

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.

1.2 How are free shipping items delivered?
Items marked as "Free Shipping" on the product page mean you do not need to pay any shipping fees. This usually applies to buyers from any country (except for certain special countries or regions).

For free shipping items, buyers cannot choose the shipping method. We will select the shipping method based on the destination country.
Typically, we use standard surface shipping methods such as 4PX, EMS, or local postal services.
We may also use UPS, FedEx, DHL, Aramex, etc., depending on the specific order and country. The final choice is at our discretion. Regardless of the shipping method used, we will notify you upon dispatch and provide a tracking number and tracking website.

• Standard tracking website: https://www.17track.net/en
• UPS: https://www.ups.com/
• FedEx: https://www.fedex.com/
• DHL: https://www.dhl.com/

Please note: If you return an item (excluding quality issues or incorrect items), you will be charged for all shipping costs incurred, including delivery, return, and customs fees.

1.3 What if I want to specify a shipping method for a free shipping item?
If you want to specify a particular shipping method (e.g., UPS or DHL) for a free shipping item, please contact us before placing your order. You will need to pay additional shipping fees, and we will ship via your preferred method.

1.4 What if I buy multiple items, some with free shipping and some that require shipping fees?
You can place your order as usual. You only need to pay shipping fees for the non-free shipping items.
