DWARF 3
List price $549 (as of Oct 2026)
Best for: Portable deep-sky imaging and travel for under $600
Our verdict
The most smart-telescope equipment for the money: light enough for a camera bag, a built-in dual-band filter, a solar filter in the box and real EQ mode. Reviewers' main complaints are early connection problems, an app with a learning curve and no tripod in the box. Planets stay tiny at 150 mm.
The DWARF 3 is a 1.35 kg (3 lb) smart telescope ("dictionary size", as Dwarflab puts it) with a telephoto camera and a wide-angle camera side by side. For $549 it includes three switchable filters, a solar filter, EQ mode and 128 GB of storage, a long list for the price. We compared Dwarflab's published specs with what reviewers found. We have not tested it ourselves; see how we research.

Image quality
With a 35 mm lens the DWARF 3 gathers a little more light than 30 mm rivals such as the Seestar S30 Pro, but its 1/1.8-inch sensor is smaller than the S30 Pro's 1/1.2-inch chip, so the S30 Pro covers more sky at the same resolution. Digital Camera World found it delivers "strong deep-sky, solar and lunar images". T3 called its images "spectacular, albeit small" and "fine for sharing and social media". Galactic Hunter's verdict was that image quality "still can't match a dedicated astrophotography rig", but that it is the "smallest yet most versatile smart telescope".
Dwarflab says the DWARF 3 dithers automatically (shifts slightly between frames) to reduce noise patterns, and both reviewers and Dwarflab stress taking fresh dark frames; the app prompts you to.
Filters and light pollution
The three filters switch automatically: VIS for daytime, an IR-extended astro filter, and a dual-band OIII + Hα filter for emission nebulae from light-polluted skies. Galactic Hunter found the scope picks the filter itself when it slews to a target. You can't add or swap filters.
EQ mode
EQ mode lets the DWARF 3 track like an equatorial mount and take exposures up to 60 seconds instead of short alt-az frames. Galactic Hunter found polar alignment took "a couple of minutes" and stars on the Veil Nebula stayed "round and pinpoint". A sturdy tripod helps; Digital Camera World found it "much easier on a tall tripod".
Connection and app
This is the weak spot in reviews. Digital Camera World said "connectivity issues between the smartphone and telescope dogged early review sessions". T3 had trouble connecting consistently and had to switch off Wi-Fi to get a stable link; firmware updates "came thick and fast but installed smoothly". The Gadgeteer found the app hard to learn without the long manual. Dwarflab publishes connection error codes and fixes; see our Dwarflab error codes guide.
What reviewers didn't like
- No tripod (every review) and only a drawstring bag for the solar filter (Digital Camera World).
- Connection problems in early sessions (Digital Camera World, T3).
- Learning curve in the app (The Gadgeteer).
- Planets are tiny (T3, Galactic Hunter, Dwarflab).
Who should buy it
- Buy it if you want the most capable scope you can fit in a camera bag for around $550, especially for travel to dark skies.
- Choose the Seestar S30 Pro if you want a larger 4K sensor, an easier app with a larger community and a tripod in the box.
- Choose the DWARF mini if weight matters most: it is 840 g.
