The Dwarf 3 is the smart telescope you take places. That's its identity, and once you accept it, almost every design decision DwarfLab made starts making sense — including the ones that look like weaknesses on a spec sheet.

The short verdict

Around $499, the Dwarf 3 is the best travel astrophotography device on the market and a genuine rival to the Seestar S50 even at home. Its 8.3MP Sony IMX678 sensor out-resolves the S50's 2MP chip, its dual-lens layout is more useful than it sounds, and its filter set is the most complete in the category. What you give up: aperture (35mm vs the Seestar's 50mm), an included tripod, and some of the polish of ZWO's app.

What's actually in the box

The scope, magnetic solar filters, a USB charging cable, cleaning cloth, and a travel bag. No tripod — you'll need any standard photo tripod or DwarfLab's own. Budget for that when comparing prices against the Seestar S50, which ships with a tripod, carry case, and solar filter at a similar price.

The dual-lens trick

The Dwarf 3 pairs a 50mm f/5 telephoto (the imaging lens, 35mm aperture) with a 13.5mm f/1.75 wide-angle lens, and both can shoot at once. In practice the wide lens earns its place three ways: it makes GoTo target acquisition fast, it captures all-sky context shots and meteors while the tele stacks a nebula, and it's an underrated nightscape camera on its own.

Image quality

The IMX678 gives you real resolution headroom — crops hold up in a way the S50's 2MP files don't. Deep-sky results on bright emission nebulae with the built-in duo-band filter are excellent for the class: the Orion Nebula, Lagoon, and North America Nebula all produce share-worthy stacks in 60–90 minutes. On small targets (planetary nebulae, galaxies beyond the showpieces) it behaves like every sub-$1,000 smart scope: capable, not miraculous.

Where it clearly beats the Seestar S50: resolution, filter flexibility (VIS, Astro, duo-band all built in on a wheel — no unscrewing anything), portability, and mosaics. Where the S50 stays ahead: raw light grab (50mm beats 35mm per minute of integration), included accessories, and a slightly more mature app.

Battery, weight, quirks

1.3 kg. It fits in a carry-on without negotiation — this is the whole point. The built-in battery runs a solid evening session; USB-C top-up from a power bank covers all-nighters. Quirks worth knowing: the app's processing pipeline is aggressive by default (turn it down and process the FITS yourself), and windy nights bother the light tripod-mounted rig more than a Seestar on its beefier legs.

Who should buy it

Buy the Dwarf 3 if you fly, hike, or drive to dark skies — or if mosaic imaging and filter flexibility matter to you. Buy a Seestar S50 (while remaining stock lasts) or S30 Pro if you shoot from a fixed backyard and want maximum photons per dollar. Either way you're getting an absurd amount of astrophotography for around five hundred dollars — this category simply didn't exist at this price five years ago.

Rating: 4.5 / 5 — the half point off is for the missing tripod and the app's occasional moods.
