Digital Camera World Verdict

The Seestar S50 is a delightful product that punches well above its weight. It may be its low price that initially tempts, but this is a hugely enjoyable product for basic astrophotography, with its low-resolution images and field rotation issues our only concern.

Smart telescopes have only been around for a few years, but until the Seestar arrived, they were a high-end purchase for early adopters. Now, everyone can afford a smart telescope, thanks to the Seestar, which has become a word-of-mouth hit that threatens to trouble the best telescopes for astrophotography in 2024. Sold out in advance of April 8’s total solar eclipse in the USA, it can take images of both the sun and moon, and deep sky targets.
