At the start of 2026, ZWO expanded its Seestar smart telescope line with the release of the Seestar S30 Pro.
But how does it compare to the original Seestar S30 and S50, and the Dwarf 3 and Dwarf Mini?
In this guide, we break down everything you need to know. Read on, or watch the video below:
What’s New with the Seestar S30 Pro?
Following the success of the S50 (2023) and the original S30 (2024), the S30 Pro aims to bridge the gap between entry-level accessibility and high-performance imaging.
While the S30 Pro retains the compact 30mm aperture of the original model, it introduces several “Pro” level upgrades:
- Quadruplet Lens System: Upgrading from a triplet to a 4-element apochromatic (quadruplet) lens. This provides a flatter field of view and superior color correction, keeping stars sharp even at the edges of the frame.
- 8.3MP Main Camera: A huge leap from the 2MP sensor found in the S30 and S50. The new Sony IMX585 sensor allows for 4K imaging with significantly better low-light sensitivity.
- 48MP Wide-Angle Camera: The secondary camera is no longer just a utility tool. With a high-resolution sensor, it can now capture Milky Way landscapes and Star Trails via a dedicated in-app mode.
- Massive Field of View: The S30 Pro offers a FOV roughly four times wider than the S50. You can now capture the entire Andromeda Galaxy in a single frame without using the mosaic mode.
- Modern Features: Includes NFC tap-to-connect and an increased 128GB internal storage capacity.
Seestar S30 Pro vs S30 vs S50
Choosing between the three Seestar models often comes down to your budget and your preferred targets.
| Feature | Seestar S30 | Seestar S50 | Seestar S30 Pro |
| Aperture | 30mm | 50mm | 30mm |
| Main Sensor | 2MP (IMX662) | 2MP (IMX462) | 8.3MP (IMX585) |
| Optics | Triplet APO | Triplet APO | Quadruplet APO |
| FOV | Wide ($2.1^\circ \times 1.2^\circ$) | Narrow ($1.3^\circ \times 0.7^\circ$) | Ultra-Wide ($4.3^\circ \times 2.4^\circ$) |
| Storage | 64GB | 64GB | 128GB |
| Price* (Approx) | $399 | $499 | $599 |

Seestar S30 Pro vs Dwarf 3 & Dwarf Mini
Dwarflab offers two strong competitors: the ultra-portable Dwarf Mini and the high-performance Dwarf 3.
S30 Pro vs. Dwarf 3 (The Main Rivals)
The Dwarf 3 is the S30 Pro’s closest competitor, but they appeal to different types of users:
- Optics: The Dwarf 3 has a slightly larger 35mm aperture and a faster focal ratio
- Detail vs. Field: The Dwarf 3 uses the IMX678 sensor, which has smaller pixels. This gives it a better image scale making it better for “zooming in” on small galaxies. The S30 Pro’s IMX585 sensor is better for capturing wide nebulae.
- Software: Seestar’s app is generally more polished and beginner-friendly, whereas the Dwarflab app provides “Expert Modes” for those who want manual control.
S30 Pro vs. Dwarf Mini
The Dwarf Mini is almost identical in core specs to the original Seestar S30 (30mm aperture, 2MP camera).
The S30 Pro outperforms the Mini in almost every category except for portability and price.
If you are a casual traveler on a tight budget, the Mini is a great entry point; if you want serious images, the S30 Pro may be a step up.
Target Guide: What Will You See?
| Target Type | Recommended Telescope | Why? |
| Large Nebulae | Seestar S30 Pro | Massive FOV; fits the North America or Orion Nebula easily. |
| Small Galaxies | Dwarf 3 | Better image scale for resolving finer details on tiny objects. |
| The Sun/Moon | Seestar S30 Pro | Quadruplet optics reduce color fringing on bright edges. |
| Milky Way | Seestar S30 Pro | The 48MP wide-angle camera is best-in-class for landscapes. |
| Planets | Neither | These are wide-field scopes; planets will always appear as small dots. |
Final Thoughts & Buying Guide
The Seestar S30 Pro is arguably the most versatile budget smart telescope of 2026.
While it doesn’t replace the S50’s light-gathering power or the Dwarf 3’s resolution on small targets, it offers the most “complete” package for hobbyists.
- Buy the S30 Pro if: You want the best user experience, 4K resolution, and love capturing large star fields and Milky Way shots.
- Buy the Dwarf 3 if: You want more manual control and focus on smaller deep-sky targets.
- Buy the S30 or Dwarf Mini if: You want the most affordable “entry ticket” to the hobby.
The latest ZWO Seestar smart telescope
- Newly released in 2026
- 8MP high-resolution camera
- Secondary wide-angle camera allowing landscape astrophotography (Milky Way, Star Trails)
- Small and lightweight
- Tripod, solar filter and carry case all included
Pro Tip: If you plan on doing long-exposure astrophotography, factor in the cost of a fluid head tripod. The basic tripods included with these units are great for Alt-Az mode but usually require an upgrade for successful Equatorial (EQ) Mode tracking.
