Celestron StarSense Explorer DX 130AZ - Smartphone app-enabled newtonian reflector telescope

The Celestron StarSense Explorer DX 130AZ combines a particularly enjoyable wide-field view of the night sky with the intelligence of StarSense navigation and the precise control of Celestron's DX manual mount.

Its 130mm parabolic primary mirror collects enough light to make deep-sky observing genuinely rewarding, while the relatively short 650mm focal length gives the telescope a broad field of view. That is a wonderful combination for exploring rich areas of the Milky Way, large star clusters, bright nebulae and galaxies.

From New Zealand, there is plenty to take advantage of. Sweep through the extraordinary star fields surrounding the Carina Nebula, explore clusters scattered along the southern Milky Way, or turn towards Omega Centauri and 47 Tucanae. Rather than simply looking at individual objects in isolation, the DX 130AZ can give you a real sense of the richness and scale of the night sky around them.

StarSense Explorer makes finding those targets considerably easier. The app shows you what is currently available to observe, lets you choose something that interests you, then guides you towards it as you move the telescope manually. You can start exploring without first having to learn constellations, star charts or traditional star-hopping.

The DX mount adds smooth, dual-axis slow-motion controls, so once you have reached an object you can position the telescope precisely and follow it as it moves across the sky.

Planets are very much part of the experience too. Saturn's rings, Jupiter and its four bright moons, Mars when favourably positioned, and the detailed landscape of the Moon all give you plenty of Solar System observing alongside the telescope's particular strengths on star fields and deep-sky objects.

For someone wanting excellent reflector optics, an engaging wide-field view and StarSense ease without moving to a large telescope, the DX 130AZ offers a very appealing all-round astronomy package.

Why Choose the StarSense Explorer DX 130AZ?

• 130mm parabolic primary mirror — quality Newtonian optics designed to produce sharp, contrast-rich views across a broad range of night-sky targets.
• Excellent for deep-sky exploration — particularly rewarding on star clusters, nebulae, rich Milky Way fields and brighter galaxies.
• Wide-field f/5 design — lets you take in larger objects and surrounding star fields rather than seeing only a narrow portion of the sky.
• StarSense smartphone guidance — shows you what is currently visible and guides you towards your chosen target.
• No previous knowledge of the night sky required — start finding worthwhile objects without first mastering star-hopping.
• Dual-axis slow-motion controls — provide precise manual movement in both altitude and azimuth.
• Strong all-round observing capability — deep-sky objects are a particular strength, while planets, double stars and the Moon remain rewarding targets.
• No telescope power supply required — StarSense provides the navigation, but the telescope and mount remain completely manual.

What Can You See?

The DX 130AZ is particularly enjoyable when exploring the deep sky.

Large open clusters can spread beautifully across the field of view, while rich areas of the southern Milky Way reveal enormous numbers of stars. Omega Centauri and 47 Tucanae appear as impressive concentrations of starlight, and the Carina Nebula provides a wonderful combination of nebulosity, clusters and surrounding Milky Way star fields.

Brighter galaxies are also within reach, particularly from darker locations. Southern targets such as the Sculptor Galaxy and Centaurus A give you another class of object to seek out as your observing experience grows.

Planets provide a very different experience. Saturn's rings are clearly recognisable, Jupiter's four Galilean moons are readily visible and its main cloud belts can appear under good conditions. Mars becomes a distinct reddish disc when favourably positioned, while the Moon reveals extensive detail across craters, mountains, ridges and shadows.

With the supplied 25mm and 10mm eyepieces, the telescope gives 26x and 65x magnification. These are particularly well suited to its broad-field character. Higher magnification for more detailed planetary observing can be added later with suitable optional eyepieces or a Barlow lens.

As with all visual astronomy, faint nebulae and galaxies are subtler through an eyepiece than in long-exposure photographs. But the DX 130AZ's combination of aperture and wide field makes searching them out and exploring the surrounding sky a particularly rewarding experience.

How StarSense Explorer Works

StarSense Explorer uses your smartphone camera to recognise star patterns overhead and determine where the telescope is pointing.

After the initial setup, the app displays objects currently available to observe. Choose a target and follow the on-screen arrows as you move the telescope manually. When the bullseye turns green, the object should be within the telescope's low-power field of view.

StarSense does not move or automatically track the telescope. It provides the navigation while you remain in control.

The app also distinguishes between objects suitable for city observing and those that benefit from darker skies, helping you choose worthwhile targets for the conditions you actually have.

DX Mount & Precise Manual Control

The DX 130AZ uses Celestron's manual Alt-Azimuth DX mount on an adjustable full-height tripod.

You can move quickly across larger areas of sky by hand, then use the geared slow-motion controls on both axes for much finer positioning once you approach your target.

That combination works particularly well with StarSense: the app gets you to the right part of the sky, while the slow-motion controls make it easy to centre the object and follow it through the eyepiece.

There are no motors, GoTo system or external telescope power requirements, keeping the observing experience straightforward while still giving you very precise control.

FAQ's

What is the DX 130AZ particularly good for viewing?

Its 130mm aperture and relatively short 650mm focal length make it particularly enjoyable for star clusters, bright nebulae, Milky Way star fields and brighter galaxies. It is also very capable on the Moon and planets, although its supplied eyepieces favour wider-field observing rather than very high planetary magnification.

Can I use the DX 130AZ from a New Zealand town or city?

Yes. Planets, the Moon, double stars and many star clusters remain rewarding from urban and suburban locations. StarSense also identifies suitable city-viewable targets. Darker skies increasingly benefit nebulae, galaxies and rich Milky Way observing.

Does the DX 130AZ automatically move to objects?

No. StarSense tells you where to point and guides you towards the target, but you move the telescope yourself. The DX mount's dual-axis slow-motion controls then make precise positioning and manual following straightforward.

Smartphone Compatibility

The Celestron StarSense Explorer app is available for supported iPhone and Android smartphones. Because phone and operating-system requirements change over time, we recommend checking Celestron's current StarSense Explorer compatibility information before purchase.
