ZWO unveiled its latest smart telescope on August 25, 2026, introducing the Seestar S50 Pro—a device designed for both amateur astronomers and solar observers. Priced at $999, this model represents a significant upgrade from its predecessor released three years earlier, commanding a $450 premium. The additional investment brings doubled storage capacity at 128 GB and enhanced 4K resolution compared to the original Full HD version. ZWO claims the unit delivers nine hours of battery life, though this specification remained unverified during testing due to an outstanding software update.
The compact telescope arrives fully equipped with all necessary accessories, including a protective carrying case, carbon fiber tripod, and solar filter for daytime observations. Its minimalist design features just two buttons and weighs only six pounds, making it portable for both backyard use and travel. During evaluation, the device demonstrated impressive performance capturing nebulae and galaxies through its live-stacking feature, with images like the Dumbbell Nebula and Andromeda Galaxy revealing rich color detail within minutes. A zero-backlash motor provides improved tracking stability compared to earlier models, though enhanced wind resistance claims require further observation to validate fully.
Despite its strengths, the Seestar S50 Pro presents some drawbacks. Initial app setup proved time-consuming, and users encountered minor software quirks including typographical errors and inconsistent exposure metering during solar eclipse imaging. The included tripod’s limited height occasionally allowed nearby vegetation to obstruct long-exposure shots. Prospective buyers should weigh whether the incremental improvements justify the premium pricing when ZWO’s more affordable S30 Pro offers comparable functionality at $300 less.
