Quick Verdict
⭐⭐⭐⭐ 4.4/5 — RECOMMENDED
The Celestron StarSense Explorer DX 130AZ takes everything that works about the LT 70AZ — the smartphone navigation, battery-free mount, fast setup — and adds a 130mm aperture Newtonian reflector. The result is a telescope that guides you to objects manually while delivering views that the smaller LT 70AZ simply cannot match. For UK beginners who want navigation help with serious aperture, this is the telescope to buy.
- ✅Buy if: You want StarSense navigation with 130mm aperture and do not need motorised tracking
- ❌Skip if: You want automatic tracking — the NexStar 130SLT adds full GoTo motors

Build Quality and Design
The DX 130AZ has a 130mm Newtonian tube, compared with the LT 70AZ. Stability can depend on setup and the supporting surface; vibration may affect high-magnification views.
Check current phone compatibility and dock fit against the manufacturer's information for your device.
📐 DX 130AZ vs LT 70AZ — Size Reality
- LT 70AZ tube: lightweight, compact
- DX 130AZ tube: 130mm, significantly larger
- Weight difference: LT 70AZ 3.3kg vs DX 130AZ 5.2kg
- Aperture difference: 70mm vs 130mm — 3.4× more light
- Verdict: Noticeably larger but still portable and manageable
StarSense Navigation Performance
The StarSense system on the DX 130AZ performs identically to the LT 70AZ — the same plate-solving technology, same app, same accuracy. The advantage of the DX 130AZ is that once StarSense guides you to an object, the 130mm aperture reveals dramatically more than the 70mm refractor.
| Condition | Setup consideration | Pointing expectation | Suggested action |
|---|---|---|---|
| Clear calm night | Clear view of stars | Depends on setup | Check centring |
| Partly cloudy | Wait for clear gaps | May need adjustment | Check visibility |
| Light rain | Protect equipment | Conditions may interfere | Follow care guidance |
| After moving telescope | Recheck phone setup | Pointing may shift | Check centring |
💡 StarSense + 130mm = Real Astronomy
The LT 70AZ shows you objects — the DX 130AZ shows you astronomy. When StarSense guides you to M13 and you see a globular cluster partially resolving into individual stars through 130mm, the experience is qualitatively different from seeing a fuzzy blob through 70mm. The navigation is the same — what you see when you arrive is not.
What You Can Expect to See
The Moon
At 26x (25mm eyepiece): If conditions are suitable, you may see the full lunar disc and shadows along the terminator.
At 65x (10mm eyepiece): If seeing is steady, you may distinguish lunar craters, mountain peaks and some rilles.
Saturn
At 65x: If seeing is steady, you may distinguish Saturn's rings, the Cassini Division and Titan.
Jupiter
At 65x: If conditions are suitable, you may see Jupiter's two main cloud bands and four Galilean moons; the Great Red Spot may be visible when facing Earth.
At 130x on best nights: If seeing is steady, you may distinguish additional cloud banding.
Orion Nebula (M42)
At 26x from suburban skies: If conditions are suitable, you may see a bright core and extensive nebulosity, with four Trapezium stars resolved; further components may be harder to distinguish.
M13 Globular Cluster
At 65x: If conditions are suitable, the cluster may appear as a fuzzy ball with some stars beginning to resolve around its edges.
At 130x: If conditions are suitable, you may resolve individual stars in the cluster's outer regions.
Andromeda Galaxy (M31)
At 26x from suburban skies: If skies are sufficiently dark, you may see the galaxy's core and inner halo.

- Deep-sky objects interest you
- Budget allows the premium
- You want a telescope to grow into
- 130mm aperture is the minimum you want to observe seriously
Who Should Buy This Telescope?
✅ YES — Buy the DX 130AZ if:
- StarSense navigation appeals
- 130mm aperture is your minimum
- You do not need motorised tracking
- Budget is between LT 70AZ and NexStar 130SLT
- Cold UK winters concern you (no mount batteries)
- You want to learn the sky while getting navigation help
❌ NO — Consider alternatives if:
- Motorised tracking is essential → Celestron NexStar 130SLT
- Budget is tight → StarSense Explorer LT 70AZ
- Maximum aperture matters → Sky-Watcher Heritage 130P
- Astrophotography is the goal → ZWO Seestar S50
Alternatives to Consider
Celestron StarSense Explorer LT 70AZ
Lower price, lighter weight. Better for beginners on a budget or those prioritising portability.
Celestron NexStar 130SLT
Same 130mm aperture with full motorised GoTo tracking. Finds and follows objects automatically.
Sky-Watcher Heritage 130P FlexTube
Same 130mm aperture, lower price, more portable. Better value for manual observing without navigation assistance.
Frequently asked questions
🏆 Our Final Verdict
The Celestron StarSense Explorer DX 130AZ occupies a unique position in the UK telescope market — more aperture than the LT 70AZ, less automation than the NexStar 130SLT, and no mount batteries at any temperature. For UK observers who want StarSense navigation with serious aperture, it is the right choice. The 130mm parabolic mirror delivers views that sustain long-term interest — and StarSense ensures you spend your rare clear UK nights observing, not searching.
Rating: ⭐⭐⭐⭐ 4.4/5
