ZWO Seestar S50 Smart Telescope vs DwarfLab DWARF 3 Smart Telescope

The Seestar S50 is the better deep-sky imager: its 50 mm apochromatic triplet gathers more light and gives sharper, cleaner results on galaxies and nebulae. The Dwarf 3 is the better travel scope: at about 1.3 kg with IP54 weather resistance and a dual wide-angle plus telephoto camera, it fits in a backpack and also shoots landscapes and wildlife. Build quality favors the Seestar's larger optics and metal filter coating; portability and battery life favor the Dwarf 3. Owners of both praise easy app control and one-tap tracking, but the Dwarf 3's small 35 mm aperture shows more noise on faint targets, and the Seestar needs care in humid storage.

  • Choose the Seestar S50 if deep-sky astrophotography is your main goal and you want the larger aperture and triplet optics to pull out faint nebulae and galaxies.
  • Choose the Dwarf 3 if you want one light, weather-resistant scope for travel that also captures wide landscapes, wildlife and the Sun.

What reviewers say

ZWO Seestar S50 Smart Telescope

Owners treat the S50 as an easy first step into astrophotography, praising how quickly it produces usable images with little setup. Complaints center on its small aperture and the limits of the app and sensor rather than on build quality.

What people mention
  • Ease of setupPraisedOwners say it aligns and starts imaging in minutes with almost no astronomy knowledge.
  • Image qualityPraisedUsers report clean, colorful stacked images of the Moon and bright nebulae straight from the app.
  • ApertureCriticisedReviewers note that 50 mm struggles with faint galaxies and small deep-sky objects.
  • AppMixedThe phone app is central to use, and users report both convenience and occasional bugs.

DwarfLab DWARF 3 Smart Telescope

  • 4.7 / 521 ratings

Rated 4.7 out of 5 from 21 ratings here, and Dwarflab reports 4.8 out of 5 from 554 reviews on its own page. Owners treat it as an easy first astrophotography setup that travels well. The recurring complaint is noise in images when dark frames are skipped.

What people mention
  • PortabilityPraisedOwners like that it fits in a backpack and sets up in minutes.
  • Image noiseCriticisedShots are noisier than usual unless dark frames are taken and applied.
  • SetupPraisedThe app, NFC pairing and auto star chart make first light quick for beginners.

Questions and answers

Which is better for photographing nebulae and galaxies?
The Seestar S50. Its 50 mm triplet collects more light, so faint nebulae and galaxies come out brighter and cleaner. The Dwarf 3 works but shows more noise on dim targets.
Which is easier to carry on a trip?
The Dwarf 3. At about 1.3 kg and IP54 rated, it drops into a backpack and shrugs off damp conditions. The Seestar S50 is roughly twice the weight and should be kept dry.
Can the Dwarf 3 shoot landscapes and wildlife too?
Yes. Its 45 mm wide-angle camera and 4K video make it usable for daytime scenery and animals, which the Seestar S50 is not built for.
Which lasts longer on a charge?
The Dwarf 3, with a 10000 mAh battery against the Seestar's 6000 mAh. Expect longer sessions before recharging, especially with the Seestar's roughly 6-hour rating.
Is the Seestar S50 worth stepping up to?
If deep-sky imaging is your priority, yes. The larger aperture and triplet lens give noticeably better faint-object results. If you want one light scope for everything, the Dwarf 3 covers more ground.
Do both track targets automatically?
Yes. Both use motorized mounts and app control to find and track objects with one tap, so neither needs manual star-hopping.
