Smart telescopes for British skies, ranked by their spec sheets

A smart telescope is a small refractor with a camera, a motorised mount and an app: it finds the target, tracks it and stacks the frames into an image on your phone. Backyard Scopes sets the models side by side the way you would fill in an observing log, with every figure taken from the maker and every UK price dated. Nothing here has been through a field trial; the rankings come from the numbers.

A smart telescope on a garden table under a clear northern sky

Four verdicts, read like the seeing

  1. Clear night

    The specifications line up for most UK gardens: enough aperture, a usable field, a battery that lasts the session.

  2. Good seeing

    Strong on most counts, with one figure that holds it back for some skies or some targets.

  3. Thin cloud

    Fine for a narrow use, such as the Moon and planets or a very light kit bag.

  4. Wait for a clearer night

    The maker leaves too many figures out, or the price buys more elsewhere on the list.

Start from your budget

  • Under £1,000

    Light, quick to set up, fine for the bright showpieces of the sky.

    5 models
  • £1,000 to £2,500

    More aperture and larger sensors, still carried out in one trip.

    6 models
  • Over £2,500

    The widest apertures and the heaviest cases, for the faint targets.
