What it's built forOpen these in the simulator →

This telescope was built for sweeping wide.

A short, fast reflector with a generous true field — the whole sword of Orion in one view, star fields that spill past the field stop. It rewards low power and dark skies far more than chasing magnification.

Widest true fieldsBright at low power

The view people remember

The Double Cluster, side by side.

Two glittering knots of stars sharing one low-power field — a wide, effortless showpiece that rewards the biggest true field you can throw at it.

Tight planetary detail belongs to a longer scope. This one trades reach for a breathtaking field.

01What it's good at

What it's best at — and the trade-offs.

130 mm at f/5 (650 mm) shows lunar detail, Saturn's rings, Jupiter's moons and brighter deep-sky objects.

Best at

✓130 mm at f/5 (650 mm) shows lunar detail, Saturn's rings, Jupiter's moons and brighter deep-sky objects.

✓StarSense plate-solves with your phone and points you to targets with an on-screen arrow.

✓The fast f/5 optics give wide, forgiving low-power views that are easy to aim.

✓A manual alt-az mount is intuitive: no alignment routine, just point and look.

Trade-offs

!The app guides but does not track, so objects drift and need re-centering.

!The lightweight alt-az mount can be a little shaky at high power.

!The fast f/5 mirror needs occasional collimation and shows some edge coma.

!It depends on a compatible smartphone in the dock to do its finding.

02In plain English

What These Numbers Mean

130mm · f/5 · 650mm FL · Alt-Az

Aperture

130 mm

Five inches of mirror gathers about 345 times the light of your eye, considerably more than the 102 mm refractor in the same range. The Orion Nebula shows structure, dozens of Messier objects are within reach, and lunar detail is plentiful.

Focal length

650 mm

Short, giving wide low-power fields that suit sweeping and phone-assisted finding. Planetary magnification depends on short eyepieces, with a realistic ceiling around 250x on steady nights.

Focal ratio

f/5

Fast optics reach a wide, low-power field easily but they are unforgiving of cheap eyepieces, which show soft and distorted stars at the edge. Collimation errors also become visible quickly at this ratio.

Optical design

Newtonian reflector

Mirrors instead of lenses, so there is no colour fringing at any magnification and the price per inch of aperture is low. You will align the mirrors occasionally and let the tube cool before critical viewing.

Weight

~8 kg complete

Roughly 18 lb including the mount and tripod, light enough to carry outside in one trip fully assembled.

Finding system

StarSense smartphone dock

Your phone photographs the sky, identifies where the telescope points and directs you to the target with on-screen arrows. It removes the single biggest source of beginner frustration without motors, batteries or an alignment routine.

Editor’s Take

The DX 130AZ pairs a 130 mm (5-inch) reflector with Celestron's StarSense phone-finder on a simple alt-az mount (it swings up-down and left-right like a camera tripod, no equatorial setup to learn). StarSense is the headline: clamp your phone on, its camera reads the star pattern to know where you are aimed, and on-screen arrows walk you to any target, no motorised GoTo needed. 130 mm is a real beginner aperture: sharp Moon and planets plus the brighter nebulae and clusters. App-guided finding on an approachable mount.
