Description
ZWO ASIAIR Plus 256G – Updated Version
The ZWO ASIAIR Plus 256G (New Version) is a powerful, all-in-one imaging controller designed to streamline your entire astrophotography workflow. Built with fast and reliable 256GB internal eMMC storage, it eliminates the TF (microSD) card slot found on earlier models—providing greater stability, faster read/write speeds, and removing the risk of card corruption during long imaging sessions.
Its compact CNC-machined aluminum chassis houses an efficient, user-friendly system that controls your ASI cameras, mounts, EAF focusers, filter wheels, dew heaters, and more. A strengthened dual-band WiFi antenna ensures stable remote operation, while the new USB-C port enables fast data transfer. Multiple 12V power outputs allow you to power your imaging accessories directly from the ASIAIR, simplifying cable management and increasing reliability.
Designed for both field and home setups, the ASIAIR Plus 256G offers smoother performance, faster processing, and a robust software ecosystem that makes deep-sky and planetary imaging easier for beginners and advanced users alike.
Kindly note that the power adapter is not included.
