Dwarf III Review: The Ultimate Pocket-Sized Astrophotography Robot (2026)
Iterating on the Dwarf II, the Dwarf III from Dwarflab features a dual-lens architecture and updated sensor geometry. It represents the only astrophotography rig capable of fitting within a hiking jacket pocket. We analyze its field performance and portability.

01Dual Lenses: Why Two are Better Than One
The standout feature of the Dwarf III is its dual-camera system. One lens is a wide-angle 'finder' and the other is a dedicated telephoto for deep sky.
The Advantage:
- Instant Orientation: Unlike single-lens scopes that can get 'lost' in the void, the Dwarf III uses its wide field to plate-solve instantly.
- The World's Best Panoramas: Because it knows exactly where it is in the sky, it can stitch together massive 50-megapixel mosaics of the Milky Way or the Moon automatically.
Dual Sony Sensors
Optimized for high-speed readout and low-noise night shots.
Ultra-Portable
Fits in a jacket pocket. Weighs under 1.2kg.
Day/Night Hybrid
AI tracking works for birds and wildlife as well as nebulae.
02Performance-to-Aperture Ratio
Despite a smaller aperture than the Seestar, the Dwarf III's 'fast' optics maintain a competitive SNR. In testing, it resolved the Helix Nebula structure in 45 minutes of integration from a Bortle 4 site.
Key Specs:
- Aperture: 35mm Periscope Design
- Focal Length: 150mm (Tele) / 24mm (Wide)
- Filters: Magnetic filter holder for UHC/OIII/Solar filters.
03The Hiking Workflow: Stars on the Summit
If you're a backpacker, the Dwarf III is your only real choice.
- The Battery Hack: It charges via USB-C. You can run it for 12+ hours straight by plugging it into a standard 10,000mAh power bank.
- The Tripod: It's so light you don't need a heavy astro-tripod. A sturdy GorillaPod is enough to keep it level on uneven rock.
- Offline Mode: The app works perfectly without cell service—essential for those deep mountain escapes.
04Dwarf III vs Seestar S50: Which to Buy?
It comes down to your primary use case:
- Buy Seestar S50 IF: You want the absolute best detail on small nebulae and galaxies. The 50mm aperture wins on raw resolution.
- Buy Dwarf III IF: You value weight above all else, or if you want to shoot massive wide-field mosaics of the sky.
Frequently Asked Questions
Q:How does the Dwarf III dual-lens system work?
The Dwarf III uses a 24mm wide-angle lens for 'star-mapping' and plate solving, and a 150mm telephoto lens for high-resolution deep-sky imaging. The wide-angle camera helps the telescope orient itself instantly, while the telephoto captures the detail of nebulae and galaxies.
Q:Is the Dwarf III better than the Seestar S50?
It depends on your needs. The Dwarf III is more portable and better for wide-field mosaics (panoramas of the Milky Way). The Seestar S50 has a larger 50mm aperture, which provides slightly better resolution and detail on small, faint deep-sky objects.
Q:Can I use the Dwarf III for birding or wildlife photography?
Yes! Unlike most astronomical telescopes, the Dwarf III has a dedicated terrestrial mode with AI-powered tracking for birds and fast-moving animals. Its compact size makes it a perfect companion for hikers and nature photographers.
Q:What filters can I use with the Dwarf III?
The Dwarf III features a magnetic filter holder that supports 1.25-inch or 2-inch filters with adapters. It is commonly used with UHC or dual-band light pollution filters for city astrophotography, as well as solar filters for daytime observing.
Q:Does the Dwarf III support RAW files (FITS)?
Yes, the Dwarf III can save both processed JPGs and raw FITS/TIFF files to its internal storage. These raw files are essential if you want to perform advanced post-processing on a computer using software like Siril or PixInsight.
