Both weigh well under 2 kg, both have 4K main sensors, built-in dual-band filters, solar filters in the box and EQ mode. They come from different philosophies, though: DWARFLAB built a dual-purpose astro and wildlife camera, while ZWO built the simplest possible pocket observatory. This comparison walks through where each one leads. We haven’t tested either telescope ourselves. The comparison draws on DWARFLAB’s and ZWO’s spec pages, live Amazon prices from November 12, 2026, and reviews by BBC Sky at Night, Space.com, Digital Camera World, Astronomy.com and Fstoppers.

Paired with a slightly shorter focal length, that gives it a faster f/4.3 against f/5.3. The sensors pull the other way. The S30 Pro’s IMX585 has larger 2.9 µm pixels on a bigger 1/1.2-inch chip, so each pixel collects more light and the frame covers more sky. The Dwarf 3’s IMX678 has smaller 2 µm pixels, giving finer sampling (about 2.75″ per pixel against 3.74″) for a little more detail on small objects. DWARFLAB can also bin those pixels 2 × 2 for astro work, which trades output resolution (down to 1920 × 1080) for sensitivity. Aperture and light grasp Bar length is light-gathering area (aperture squared), so a 114 mm mirror collects about 5× what a 50 mm lens does.

See [how smart telescopes work](https://smarttelescopereview.com/posts/how-smart-telescopes-work/). Net result: neither has a decisive optical edge, and no outlet we found has shot the two side by side. The Dwarf 3 resolves a bit more on small galaxies; the S30 Pro takes in more sky per frame. Neither is a planetary scope. Astronomy.com says the Dwarf 3’s focal length is too short for detailed planets, Space.com found its planets weren’t crisp, and BBC Sky at Night caught Jupiter’s disc and moons with the S30 Pro but no detail. ## Field of view The S30 Pro’s field is about 3.99° × 2.24°; the Dwarf 3’s is about 2.93° × 1.65°. Native field of view How much sky the main camera frames in one shot (bar length = area in square degrees). The full Moon is about 0.5° across.

Try any target in the [framing calculator](https://smarttelescopereview.com/tools/fov-calculator/). - **The Andromeda Galaxy** (about 3° long) fits in one S30 Pro frame. On the Dwarf 3 it slightly overflows the frame, so you’d use its 2 × 2 mosaic. [Compare M31 on the Dwarf 3](https://smarttelescopereview.com/tools/fov-calculator/#target=m31&scope=dwarf-3) with [M31 on the S30 Pro](https://smarttelescopereview.com/tools/fov-calculator/#target=m31&scope=seestar-s30-pro). - **The Orion and Rosette nebulae** fit comfortably on both. [See the Rosette on the Dwarf 3](https://smarttelescopereview.com/tools/fov-calculator/#target=ngc2237&scope=dwarf-3). - **Small galaxies** like M51 are tiny on both; the Dwarf 3’s finer sampling helps slightly. Check how long a target takes from your own sky with the [integration time tool](https://smarttelescopereview.com/tools/integration-time/#target=m42&scope=dwarf-3&bortle=7). ## Battery, weight and build DWARFLAB measured up to 5.5 hours from the Dwarf 3’s 10,000 mAh battery at room temperature. Reviewers got less: [Digital Camera World](https://www.digitalcameraworld.com/optics/telescopes/dwarflab-dwarf-3-smart-telescope-review) about four hours, and BBC Sky at Night just over four in near-zero temperatures. ZWO rates the S30 Pro’s 6,000 mAh battery at about 6 hours; we haven’t seen an independent measurement. Both charge over USB-C. DWARFLAB supports external power for the Dwarf 3, so a [power bank](https://www.amazon.com/dp/B0C3GTMX5M?tag=smarttelescopereview.com-20) can extend a long night; for the S30 Pro, check ZWO’s manual for powering it while observing. The Dwarf 3 is 300 g lighter (1.35 kg) and IP54-rated against dust and splashes. The S30 Pro has an active anti-dew heater. Both have 128 GB of storage and two-year warranties. ## Tripods and EQ mode The S30 Pro ships with a mini tripod; the Dwarf 3 doesn’t, and Digital Camera World lists that as a con. DWARFLAB’s [mini tripod with hydraulic head](https://www.amazon.com/dp/B0FF4G7CMJ?tag=smarttelescopereview.com-20) costs about $89, bringing the Dwarf 3 to roughly $638 all in. Both support EQ mode, which removes field rotation for cleaner long stacks. The Dwarf 3 does it by tilting the unit to your latitude on a tripod head, and DWARFLAB quotes 60-second exposures. The S30 Pro needs ZWO’s [TH10 head and TC20 tripod bundle](https://www.amazon.com/dp/B0FN82ZLHM?tag=smarttelescopereview.com-20) (about $180). Our [EQ mode explainer](https://smarttelescopereview.com/posts/smart-telescope-eq-mode-explained/) covers both approaches. ## Filters Both have a built-in dual narrowband filter for emission nebulae from light-polluted skies. The Dwarf 3’s H-alpha passband is narrower (15 nm vs 20 nm). Both include a solar filter, and BBC Sky at Night lists two in the Dwarf 3’s box. If you want to add a 2-inch filter to the Dwarf 3, a third-party [M48 adapter](https://www.amazon.com/dp/B0HRFJWVPW?tag=smarttelescopereview.com-20) (about $32) makes room for one such as the [Optolong L-eNhance](https://www.amazon.com/dp/B07SY93LHN?tag=smarttelescopereview.com-20). Our [filters guide](https://smarttelescopereview.com/posts/best-filters-for-smart-telescopes/) explains which type helps where. ## Daytime use and wide cameras This is the Dwarf 3’s clearest win. It’s designed for auto-tracking wildlife and landscape photography as well as astronomy, and the weather sealing makes field use less nerve-racking. If one device has to serve as a long lens for birds by day and a telescope at night, it’s the Dwarf 3. The S30 Pro’s wide camera is the stronger night tool: 4K at 63°, with 8K Milky Way stitching. The Dwarf 3’s wide camera is 1080p at 50.6° diagonal. ## Apps and ease of use The Seestar app has a reputation for simplicity. Fstoppers noted that capture carries on if the app disconnects, and it supports ASCOM Alpaca and NINA for advanced users. Digital Camera World’s main cons were full reliance on the phone app and frequent data downloads. The DWARFLAB app does more, especially for daytime shooting, but Space.com found image capture time-consuming flagged its range and wanted better instructions. BBC Sky at Night still gave the Dwarf 3 four stars, the same as the S30 Pro. ## Verdict by user type - **First smart telescope, simplest nights:** S30 Pro. Tripod included, easier app, widest field.

It depends on use. The Dwarf 3 has a bit more aperture (35 mm vs 30 mm), finer pixel sampling, an IP54 body and strong daytime wildlife features for about $549. The S30 Pro has a wider field, a better wide-angle camera, a simpler app according to reviewers, and a tripod included, for about $664 on Amazon (Nov 12, 2026). ### Does the Dwarf 3 come with a tripod? No. Digital Camera World lists the missing tripod as a con. DWARFLAB's mini tripod with a hydraulic head costs about $89 and also makes EQ mode easier. The S30 Pro ships with a mini tripod. ### Which has better battery life, the Dwarf 3 or the S30 Pro? On paper, the S30 Pro: ZWO rates it at about 6 hours. DWARFLAB measured up to 5.5 hours for the Dwarf 3 at room temperature, but Digital Camera World got about four hours and BBC Sky at Night just over four in near-zero temperatures. Both charge over USB-C, and DWARFLAB supports external power for the Dwarf 3. ### Can the Dwarf 3 or S30 Pro photograph planets? Only as small discs. Astronomy.com says the Dwarf 3's 150 mm focal length is too short for detailed planetary images, and Space.com found its planets weren't crisp. BBC Sky at Night captured Jupiter and its moons with the S30 Pro but no detail, and ZWO says it isn't intended for planets. ### Which is better for wildlife and daytime photography? The Dwarf 3. DWARFLAB built it as a dual-purpose device with auto-tracking for wildlife and landscape shooting, and its IP54 rating helps outdoors.
