How do you choose a first telescope in the UK?
Three rules cover most of it. Aperture first, a simple mount second, and buy from a specialist, not a department store.
Aperture firstBigger mirror, more to see. 130mm shows the Moon and planets well; 200mm brings in galaxies. Aperture matters more than magnification, brand or "computerised".
Dob beats EQA Dobsonian points where you push it. Equatorial mounts need aligning every session, and most beginners give up on them.
Skip the kit scope"675× magnification" on a 60mm tube is the warning sign. Buy from a specialist astronomy retailer, not a catalogue or department store.
Aperture is king
The single most important number on any telescope is the aperture, the diameter of the primary mirror or lens. A larger aperture gathers more light, so you see fainter objects and more detail. Everything else, focal length, mount type, brand, is secondary. Our guide to telescope magnification explains why the big number on the box means nothing.
Dobsonian vs equatorial vs GoTo
A Dobsonian mount is the simplest: push and look. An equatorial mount tracks the sky's rotation with one axis, which is useful for photography and long sessions. A GoTo mount finds objects automatically. Beginners almost always have the best experience with a Dobsonian: less to go wrong, less to learn before your first good view. Our guide to how to use a telescope covers the first night with any of them.
Reflector vs refractor
Reflectors (mirror-based) give you more aperture per pound and excel at deep-sky objects. Refractors (lens-based) give pin-sharp, high-contrast views and need no maintenance, but cost much more for the same aperture. For most beginners a reflector is the better value.
Don't forget the eyepieces
The eyepieces bundled with most telescopes are functional but basic. Budget an extra £45 to £80 for one good eyepiece; it will transform what you see. See our eyepiece guide for specific recommendations, and how to collimate a telescope for the five-minute check that keeps a reflector sharp.
The tabletop question
The Heritage 130P and 150P are tabletop scopes and need a sturdy surface at waist height. If you don't have a suitable table in the garden, factor in a stool or plant stand (£15 to £30). The Skyliner 200P and NexStar 6SE stand on the ground on their own.
Not sure a telescope is right yet?
Binoculars are the cheaper first step and many observers never stop using them. Our best binoculars for stargazing guide starts at £84, and if you'd rather photograph the sky than look through an eyepiece, see how the Seestar S50 and Dwarf 3 smart telescopes compare.
