ASIAIR alternative: AStarBox

AStarBox, a new astro imaging computer, is set to shake up astrophotography by offering a lightweight, powerful, and open platform that simplifies the imaging process for astronomers. With its debut on the horizon, AStarBox aims to help folks break out of the proprietary realms like ZWO, and use any equipment you want, plus power it (up to 30A).

The lightweight, powerful, astro imaging computer AStarBox

At the core of AStarBox’s innovation is its lightweight design. Weighing just 222 grams, it’s remarkably easy to handle, making it ideal for portable setups. The unit includes a guider foot mount, allowing it to be securely mounted on scopes, with third-party mounting solutions also available for further customization. It is designed to utilize the same connections as the widely popular ASIAir, ensuring compatibility with existing systems. AStarBox is initially available as a DIY kit, enabling users to add their own Raspberry Pi 5 and SD card to complete the build. This approach provides flexibility and allows users to customize their system according to their specific needs.

One of the most significant aspects of AStarBox is its open platform, which distinguishes it from other proprietary astro imaging computers. Rather than being locked into a particular software ecosystem or hardware provider, imagers have the freedom to choose their software and hardware setups. AStarBox is capable of running any software compatible with the Raspberry Pi, including popular astro imaging programs like Indi, TheSky, Firecapture, PHD2, and AstroDMx. This open-ended approach allows for maximum versatility, enabling users to tailor the device to suit their specific imaging workflows and equipment.

The device’s computing power is also a key highlight. Powered by the Raspberry latest Pi 5, AStarBox offers a computing boost that is 250% faster than earlier Pi 4-based products. The Pi 5’s dedicated IO chip provides seamless high-bandwidth connections to CMOS cameras, significantly improving download speeds and enhancing the stability of large file transfers. Additionally, the integration of a real-time clock in the Raspberry Pi 5 enables accurate timekeeping even when used in remote, internet-free locations. For users requiring GPS functionality, AStarBox supports external GPS dongles, which can be used to set location data in compatible software like TheSky and Indi.

Simplify your imaging with open software flexibility and powerful device control

AStarBox also delivers comprehensive control over power management, another feature that sets it apart. The power board, designed by Rodolphe Pineau, an experienced developer of astro device boards, supports up to 30 amps of power across four power sockets and two dew heater sockets. Each socket can supply up to 5 amps of current, and the unit is capable of powering USB devices that require higher currents. To ensure safety and longevity, the system includes auto-resetting fuses, and its XT 60 connectors provide stability for high-current applications.

AStarBox is more than just a controller for imaging devices—it is a complete power and control hub for astrophotographers. From powering cameras and dew heaters to managing software connections and data transfers, AStarBox consolidates all essential imaging functions into a single device. Its versatile design enables users to eliminate much of the wiring complexity commonly associated with astroimaging setups, simplifying the overall experience.

The first production run of AStarBox kits has already been completed, with the initial batch delivered to First Light Optics for distribution across the UK and Europe. Customers in the US and Canada will soon be able to purchase the device through Cloud Break Optics, with a second manufacturing run already underway. These kits provide everything needed to get started, with custom cables also available from First Light Optics for those requiring additional accessories.
