In-depth review
Updated September 2026 · Written by the TelescopeReviews.co.uk test team
⭐⭐⭐⭐ 4.2/5 — RECOMMENDED
The best budget entry into smart astrophotography we have tested. Across 12 sessions under UK skies, the Dwarf III produced genuinely impressive images of nebulae, galaxies and the Moon with almost zero learning curve. It is our top budget pick in the best smart telescope uk round-up and the easiest way into astrophotography that we have found.
| Optical design | Refractor (wide-field) |
|---|---|
| Aperture | 35mm equivalent imaging system |
| Focal length | 150mm (telephoto) / wide-angle dual lens |
| Camera sensor | Sony IMX678 (4K) |
| Mount type | Integrated motorised alt-azimuth |
| Control | Smartphone via free DwarfLab app (iOS/Android) |
| Features | Auto GoTo, plate solving, live stacking, timelapse |
| Battery | Built-in rechargeable (approx. 3-4 hours) |
| Weight | Approx. 1.2kg with tripod |
| Best for | Nebulae, wide-field deep-sky, Moon and Sun (with filter) |
The Dwarf III is the smallest and lightest smart telescope we have tested. At roughly 1.2kg with its mini tripod it slips into a rucksack alongside a jumper and flask — genuinely important for UK stargazers who often drive to darker skies. The white plastic body feels more consumer-gadget than premium instrument, but after 12 sessions including dew-soaked November nights it showed no issues.
The dual-lens design — a telephoto lens for deep-sky and a wide-angle lens for daytime and Milky Way shots — is unique at this price and makes the Dwarf III genuinely useful even when the clouds roll in.
🔧 Build Highlights
There is no polar alignment, no finder scope and no collimation. Here is exactly what first-time setup looks like:
Step 1 — Charge and download the app
Charge the Dwarf III fully via USB-C and install the free DwarfLab app on iOS or Android before your first session.
Step 2 — Level the unit
Place the Dwarf III on its mini tripod or any standard camera tripod and level it roughly. The built-in plate solving tolerates a slightly imperfect setup.
Step 3 — Connect via Wi-Fi
Power on and join the Dwarf III's own Wi-Fi network from your phone. The app connects in seconds and no internet is needed in the field.
Step 4 — Calibrate and pick a target
The app runs an automatic calibration and plate solve. In our testing this took 2-3 minutes from power-on to imaging the first target.
Step 5 — Stack and watch the image build
Choose an object from the built-in catalogue and tap start. The live stack builds on your phone screen in real time — our M42 result showed clear nebulosity within 5 minutes.
💡 Our First-Light Experience
From opening the box to a stacked image of the Orion Nebula took 25 minutes, and most of that was charging. By the second session we were imaging within 5 minutes of stepping into the garden. No telescope in our test programme — smart or traditional — gets a beginner to a result faster.
All results below were captured by our test team from suburban and rural UK locations between October 2025 and March 2026.
Verdict: Outstanding — the single best first-target result of any smart telescope we have tested at this price.
Verdict: Excellent — a genuinely shareable Andromeda image from a light-polluted UK garden.
Verdict: Superb — the easiest lunar imaging we have ever done, and ideal for sharing with family.
Verdict: Very good — rewarded patience; short stacks show the stars, long stacks start to reveal the nebula.
Verdict: Good for the conditions — the filters genuinely work, but dark skies still win for galaxies.
The free DwarfLab app (iOS and Android) handles everything: connection, calibration, target selection, live stacking and saving. The built-in catalogue covers the Messier list, bright NGC objects, the Moon and the Sun (with the included solar filters), plus a timelapse and panorama mode for daytime use.
Across 12 sessions the app connected first time on 10 occasions. Two sessions needed a Wi-Fi reconnect after the phone screen locked — a minor irritation, and the stack resumed without losing data. Images save directly to your phone as JPEG or FITS files for further processing if you want it.
📱 App Features We Used Most
The most common question we receive. We tested the Dwarf III side-by-side with the ZWO Seestar S50 on the same nights:
| Category | Dwarf III | Seestar S50 |
|---|---|---|
| Field of view | Wider — frames M31 and large nebulae | Narrower — better for small galaxies |
| Camera | Sony IMX678 4K sensor | Sony IMX462 sensor |
| Weight | Lighter and more portable | Compact but heavier |
| App and stacking | DwarfLab app, live stacking | Seestar app, live stacking |
| Daytime use | Telephoto and wide-angle terrestrial modes | Limited to solar and night use |
| Best for | Beginners wanting versatility and value | Those wanting a slightly more polished night-only experience |
💡 Our Head-to-Head Verdict
On large targets like Andromeda and the Rosette Nebula, the Dwarf III's wider field was the clear winner. On small galaxies and globular clusters the Seestar S50 pulled ahead. For a first smart telescope on a budget we recommend the Dwarf III; if budget is flexible, the Seestar S50 is the more polished night-only instrument. The Vaonis Vespera II sits above both for pure refinement.
✅ Perfect for
❌ Not ideal for
The benchmark smart telescope — a more refined night-imaging experience and stronger community support, at a higher price.
Premium build, fully automated and beautifully designed — the luxury option for effortless deep-sky imaging.
A traditional manual telescope with far more aperture for visual observing — better if you want to look through an eyepiece.
The Dwarf III earns its place as our best budget smart telescope for 2026. Twelve UK sessions proved it delivers images that would have demanded hundreds of pounds of camera gear and months of learning just a few years ago — and it does it from a light-polluted back garden, controlled entirely from a phone. The 4.2/5 score reflects the plasticky build, modest battery life and the absence of an eyepiece, but for effortless astrophotography at the lowest price in the category, nothing else comes close.
⭐⭐⭐⭐ 4.2/5 — the best budget entry into smart astrophotography for UK buyers.
