What happened

ZWO released the Seestar S50 Pro on August 25, 2026, a smart telescope priced at $999—$450 more than the original S50 released three years prior. The Pro model features 4K resolution (8.3 MP, 3840 x 2160), 128 GB internal storage (double the original), and a claimed 9-hour battery life versus the originally stated 7 hours. The device includes a dual-lens system, motorized alt-azimuth mount with equatorial mode support, 50mm aperture, and ships with a solar filter, premium tripod, and protective carry case. Testing confirmed strong performance on deep sky objects including the Dumbbell Nebula, Andromeda Galaxy, and paired observations of Bode's and Cigar galaxies using live-stacking features, as well as solar imaging during the August 12, 2026 solar eclipse. The reviewer noted automatic alignment and tracking function, though manual joystick adjustment was sometimes needed for perfect centering.

Context

The S50 Pro represents ZWO's most advanced offering in its smart telescope line, designed to appeal to astronomy enthusiasts seeking premium capabilities in a portable package weighing 6 pounds. The device's 9-hour battery claim (stated as untestable at time of review due to pending app version 3.3.1 release) and 4K imaging capability distinguish it from the base S50, though the substantial price increase raises the question of whether these upgrades justify the additional cost for consumers. The compact form factor and included accessories position it as a complete system requiring no additional purchases, though the reviewer identified limitations including a very short included tripod and occasional app interface issues, and noted the S30 Pro as a lower-cost alternative for budget-conscious buyers.

What's disputed

The 9-hour battery life specification remains untested and unconfirmed in the review, as the app version responsible for this performance upgrade had not been released during testing.
