The ZWO Seestar S50 I reviewed in May is out of production. Walk into the smart-telescope aisle today and the Seestar you can actually buy new is a 30 mm scope: the S30 or the S30 Pro. The “successor” has 20 mm less aperture than the thing it replaced. If you’ve spent any time reading telescope forums, that sentence should make you flinch, because aperture is the one number those forums agree on. The question I keep getting emailed: does a 30 mm smart telescope give up too much from a light-polluted balcony, and should you hunt down a used S50 instead? ...

The ZWO Seestar S50 sat on my balcony railing in Nicosia for 47 sessions between November 2025 and April 2026. I pointed it at globulars, planetaries, galaxies, the Moon, and — twice — Jupiter. After six months I know exactly who should buy one and, more usefully, who should save the money for something else. The setup that kept me coming back The S50 weighs 1.5 kg. I carry it out with one hand, set it on the railing, open the app, and I’m imaging within three minutes. No polar alignment, no balance weights, no multi-star alignment routine. The internal plate solver — the same astrometry.net algorithm I wrote about last month — handles pointing. Tap an object, the telescope slews, stacking begins. ...
