DwarfLab DWARF 3 Smart Telescope

A 6-Element, 35mm Apochromatic Optical System

The DWARF 3's telephoto lens uses a 6-element apochromatic lens group with multiple ED (Extra-low Dispersion) lenses, which reduce chromatic aberration and enhance sharpness. The 35mm aperture and 150mm focal length give a 35mm-equivalent focal length of 737mm, with single exposures of up to 60 seconds in Equatorial Mode.

A secondary wide-angle camera with a 3.4mm aperture offers a 45mm equivalent focal length. Its 50.6° diagonal field makes it easier to spot targets quickly, and DwarfLab pairs the two cameras so the telephoto lens can take over once a target is selected.

Dual Sony Sensors: 8 MP IMX678 and 2 MP IMX307

At the core of the telephoto system is the Sony IMX678 Starvis 2 sensor, a high-sensitivity, low-noise 1/1.8" chip. It delivers a native resolution of 3840 x 2160 (8 MP) with 2 µm pixels, and 2x2 binning gives 4 µm effective pixels.

The wide-angle camera employs a 1/2.8" Sony IMX307 sensor with a resolution of 1920 x 1080 (2 MP). Select a target in the DWARFLAB app's star chart and the DWARF 3 automatically locates and tracks it.

3 Integrated Filters: VIS, Astro, and Hα/OIII Dual-Band

The DWARF 3 telephoto camera has three built-in filters, switchable from the DWARFLAB app. This allows you to adapt your imaging strategy to the target and local sky conditions without any external accessories.

• VIS Filter (440-640 nm): DwarfLab's standard filter for daytime and regular shooting; it blocks infrared light for natural colors.
• Astro Filter (440-670 nm): A broadband filter suitable for deep space and low-light environments.
• Dual-Band Filter (OIII & Hα): This narrowband filter isolates two key emission lines: Oxygen-III at 500.7 nm (30 nm FWHM) and Hydrogen-alpha at 656.3 nm (15 nm FWHM). It significantly reduces the impact of urban light pollution and enhances the contrast and detail of emission nebulae.

A 3.38° Diagonal Field of View with 2x2 Astro Mosaic

A single 3.38° diagonal telephoto field can cover the entirety of most deep-sky objects.

For larger targets, the Astro Mosaic function uses a 2x2 stitching mode to expand the shooting area of a single frame to four times its original size. You can rotate and zoom to compose freely.

Automated Imaging with GoTo, Live Stacking, and 60s Exposures

The DWARF 3 streamlines the entire astrophotography process. After a quick setup, you select a target from the built-in star chart in the DWARFLAB app, and the telescope automatically locates and tracks it.

It captures a series of sub-exposures, up to 60 seconds each in Equatorial Mode, and the built-in stacking combines them into a cleaner image. Equatorial Mode also eliminates field rotation; the DWARF 3 has no field derotation of its own.

Scheduled Shooting and Multi-Night Stacking for Unattended Sessions

For advanced projects, the DWARF 3 supports fully automated and unattended operation. Using the Scheduled Shooting feature, you can plan an entire imaging session in advance, setting the target and exposure parameters. The DWARF 3 automatically starts shooting at the scheduled time, so you do not need to stay up all night.

The system also supports multi-night stacking. You can combine data captured across several different nights on the same target to increase the total integration time. This enhances clarity and reduces noise. The DWARF 3 can even continue an imaging sequence if the app is closed or the connection is lost, letting you reconnect later to check progress.

Stellar Studio: In-App Post-Processing with 1-Click Optimization

The DWARFLAB app includes a built-in processing suite called Stellar Studio, allowing you to go from raw data to a finished image directly on your phone or tablet. For beginners, a one-click optimization tool automatically adjusts the image for a great-looking result. More advanced users can take manual control over individual processing steps.

• Processing Tools: Adjustments include noise cancellation, star correction to refine star shapes, and even star removal to isolate and enhance nebulosity.
• Flexible Output: You can save JPG or PNG for sharing, or FITS and TIFF for post-processing in your own software. Stellar Studio needs an internet connection.

Beyond Deep Sky: Solar, Lunar, and Daytime Imaging

The DWARF 3 is a multi-purpose imaging tool. With the included magnetic ND solar filter attached, DwarfLab offers one-click sun lock and stable tracking, with sunspots clearly visible. It also tracks the Moon steadily so you can record each phase.

Its capabilities extend to wide-field astrophotography, with dedicated modes for capturing the Milky Way and creating star trail images and videos. During the day, it works for bird watching: after identifying the target, the DWARF 3 locks on and tracks it, and AF-C continuous autofocus follows moving subjects. Its panorama mode stitches telephoto burst shots into one wide image; DwarfLab does the stitching in the cloud.

5.5 Hours of Imaging with a 10000 mAh Battery and 128 GB Storage

Engineered for portability and field use, the DWARF 3 is powered by a built-in 10000 mAh battery. DwarfLab's measured average at room temperature is up to 5.5 hours of astrophotography. Power input is USB-C, and the battery supports external USB charging.

All images and data are saved to the 128 GB of built-in eMMC storage. Connectivity is handled via Wi-Fi and Bluetooth with a range of up to 20 meters, and NFC one-touch connection speeds up pairing. The telescope mounts to any standard photo tripod via a 1/4" thread.

IP54 Rated and 1350g: Your Go-Anywhere Smart Telescope

Weighing 1350 g and measuring 222 x 142 x 65 mm, the DWARF 3 is easy to take along for travel, camping or weekend outings, and it ships with a storage bag. An IP54 rating provides protection against dust and dew, giving you peace of mind when imaging outdoors in changing conditions.

The entire system is self-contained, requiring only your smartphone and a tripod for a complete imaging setup. DwarfLab's spec table gives an operating temperature of -10 to 45°C.

DWARF 3 vs. DWARF mini: Aperture, Resolution, and NPU

While both are highly portable smart telescopes, the DWARF 3 offers significant hardware upgrades over its sibling, the DWARF mini. The DWARF 3 has the larger aperture, the higher resolution sensor and the faster NPU.

• Aperture and Optics: The DWARF 3 features a 35mm aperture compared to the DWARF mini's 30mm, giving it over 36% more light-gathering area.
• Sensor and Resolution: The DWARF 3 uses an 8 MP Sony IMX678 sensor, capturing four times the resolution of the DWARF mini's 2 MP IMX662.
• Processing Power: With a 5 TOPS NPU (Neural Processing Unit), the DWARF 3 has five times the processing power of the DWARF mini's 1 TOPS NPU.
• Storage: The DWARF 3 includes 128 GB of internal storage, double the 64 GB found in the DWARF mini.
