If you’ve been thinking of getting into astrophotography but the expense and the need for telescopes, laptops and gear galore puts you off, check out the SeeStar S30. Small enough to pack alongside a DSLR or mirrorless camera in a photography backpack, this smart telescope is more lens-sized than telescope-sized, and is designed to put deep-sky photography in reach of absolute beginners.
Built by Chinese company ZWO — a respected name in specialist astrophotography cameras  — and a follow-up to the larger Seestar S50, this diminutive smart telescope is built around a smaller 30mm/1.18 inch aperture refractor telescope. Automatically slewing to, and taking image after image of, deep-sky objects, it auto-stacks to remove noise and creates colorful images of galaxies, star clusters and nebulae. What’s the catch?
