We introduced the Seestar sub-brand, dedicated to developing popular, lightweight, and innovative astronomy products, bringing intelligent telescopes into households worldwide. We are proud to announce the release of the Seestar S50. This clever telescope integrates a telescope, motorized mount, astronomical camera, ASIAIR controller, heater belt, and filter-switching device.

We introduced the fifth edition ASIAIR: ASIAIR Plus 256G, equipped with a self-developed motherboard that ensures stability and reliability. With an eight-fold increase in storage capacity, astronomy enthusiasts can now easily enjoy capturing various celestial objects.

We introduced the ZWO FF series telescopes, featuring a unique lens design and powerful field flattening capabilities, so the telescopes ensure high-quality star images, enhance image stability, and significantly reduce spherical and chromatic aberrations impact on photographs.

We introduced the AM3, another addition to our AM series of harmonic equatorial mounts that do not require a counterweight. The design of the AM3 not only prioritizes portability but also emphasizes ensuring stability and structural rigidity during usage, going beyond the sole focus on the lightweight of the main body.

The brand image and brand strategy have undergone a comprehensive upgrade. "To empower and inspire your universal journey" is our motto. Through continuous innovation, we aim to provide more convenient services and more intelligent products for astronomy enthusiasts.

AstroNet platform launches, aiming to create an equitable and healthy communication platform for astronomy enthusiasts worldwide, and actively collaborating to promote popular astronomy education.

We introduced the fifth edition ASIAIR: ASIAIR Mini. The most portable ASIAIR ever. 42% smaller in size than ASIAIR Plus and 21% lighter. Meanwhile, the ASIAIR v2.0 was also released, featuring a new astrophotography online community. The 2.0 version marks the ZWO complete ecosystem shaped initially.
