What is the Dwarf 3?

🔭

A complete imaging system

The Dwarf 3 combines a telescope, astronomy camera, motorised mount, internal filters, and onboard computer in a single portable unit weighing 1.35 kg. There is no separate mount, no separate camera, and no laptop required in the field.

📱

App controlled

Everything is operated via the free DWARFLAB app on iOS or Android. The app handles GoTo targeting, filter selection, exposure control, live stacking, and image management. The Dwarf 3 connects via WiFi — either directly to your phone or through your home network in STA mode.

Designed for beginners

Unlike traditional astrophotography setups that require polar alignment, focusing, guiding, and dedicated processing software, the Dwarf 3 handles all of this automatically. Auto Parameters mode selects settings, autofocus handles focus, and live stacking builds the image in real time.

🌙

What it can image

Deep sky objects (nebulae, galaxies, star clusters), the Moon, Sun (with solar filter), planets, the Milky Way, and daytime subjects. The dual-lens design — telephoto for detail, wide-angle for wide field — handles all of these without changing optics.

First-time Setup

1
Charge the battery before first use
Use a USB-C to USB-C cable with PD2.0/PD3.0 fast charge support (18W, 12V/1.5A). A slow USB-A cable will charge but takes significantly longer. The battery indicator on the unit shows charge level in four segments. The Dwarf 3 can be used while charging and works with power banks — useful for all-night sessions.
Cold weather note: Below 0°C, charging slows or pauses to protect the battery. This is normal. If sensor temperature exceeds 60°C the unit will shut down automatically for protection.
2
Download the DWARFLAB app
Available free on iOS and Android. Your phone or tablet must support Bluetooth 4.0 and WiFi 5GHz. Before connecting: turn off any VPN, ensure Bluetooth, WiFi, and Location permissions are all enabled, and grant the app all requested permissions. An internet connection is required for first-time activation and firmware updates.
Tablet without cellular data: Go to Settings → Connection Settings → Enable STA Mode, then connect to your Dwarf 3, then tap Activate.
3
Mount on a tripod and power on
The Dwarf 3 uses a standard 1/4"-20 UNC tripod thread — any camera tripod works. Mount securely. Short-press the power button to turn on. Level the unit as accurately as possible — good levelling is especially important when using EQ Mode for longer exposures.
NFC quick connect: Hold your phone's NFC reader under the ring light until prompted. The app opens and connects automatically — no manual pairing needed.
4
Activate the device
On first use the app will prompt activation — required to enable all features and register the 2-year warranty. Follow the in-app prompts. You can check activation status later in Settings → My Device → Activation Status. Activation requires an internet connection.
5
Install firmware updates
Check for firmware updates before your first imaging session. Updates add features, fix bugs, and improve tracking. The DWARFLAB app handles updates over WiFi. Allow updates to complete fully before use.
Tip: Do this at home with a stable internet connection, not in the field on a clear night.
6
Select a target and start imaging
In the app, tap the star chart icon and select Tonight for the best targets currently above your horizon. Tap a target, then the camera icon to begin tracking. The Dwarf 3 will slew, locate, and lock onto the target automatically via plate-solving. Select your filter, set your parameters (or use Auto Parameters to start), and tap the shutter button. The live stack builds in real time on screen.
First target recommendation: Start with the Moon or a bright open cluster like the Pleiades (M45). Bright targets give immediate visual feedback and let you verify focus and tracking before attempting faint DSOs.
7
Take dark frames before finishing
Before packing up at the end of a session, use the built-in dark frame tool in the app. Cover the lens and let the Dwarf 3 capture a set of dark frames at the same temperature as your session. These are used to subtract thermal noise and hot pixels during processing. They must be taken at session temperature — re-take them if temperature changed by more than ±8°C during the session.
Important: Do not take dark frames immediately after bringing the unit indoors. The sensor temperature will have changed.

Imaging Modes

Astro
Night
The primary deep sky imaging mode. Captures, aligns, and live-stacks multiple sub-frames in real time. Supports Auto Parameters (up to 15s) and Manual mode (up to 60s). Includes EQ Mode for field rotation compensation. All filter choices are available here.
Lunar
Night
Optimised for the Moon. Auto Parameters work reliably here — typically 1/400s–1/250s exposure, gain 0, VIS filter. The Dwarf 3 detects and centres the Moon automatically. Best results come from imaging near the terminator (day/night line) where crater shadows create the most detail.
Solar
Day
For imaging the Sun — sunspots, solar granulation. The magnetic clip-on solar filter must be attached before entering this mode. The app applies appropriate parameters automatically. VIS filter only. Never point at the Sun without the solar filter in place.
Time Lapse
Day / Night
Captures a sequence of frames at a set interval for time lapse video creation. Useful for star trails, cloud movement, or sunset/sunrise sequences. The Dwarf 3 handles the interval timing automatically.
Panorama
Day / Night
Captures multiple adjacent frames that are automatically stitched into a wide panorama. Works with both telephoto and wide-angle lenses. The Pano Weave cloud tool (Infinity Lab) can stitch ultra-detailed telephoto panoramas automatically.
General / Video
Day / Night
Daytime photography, birdwatching, and landscape use. Continuous Autofocus (AF-C) is available here for daytime subjects. Supports video at up to 4K. The wide-angle lens is well-suited to landscape and Milky Way work in this mode.
Mosaic Mode
Night · EQ required
Captures multiple adjacent telescope fields and stitches them together to image targets larger than the single-frame field of view. Useful for extended targets like M31 (Andromeda) and NGC 7000 (North America Nebula). Requires EQ Mode to be active.
Scheduled Shooting
Night
Set a target and start time in advance. The Dwarf 3 begins imaging automatically at the scheduled time — no need to stay awake. Useful for targets that rise late, or for maximising sessions during short clear weather windows.

Built-in Filter Guide

VIS
Full visible spectrum
For daytime photography, the Moon, and the Sun (with the clip-on solar filter). Passes the complete visible wavelength range. Not suitable for faint deep sky work — too much sky background is included.
Moon Sun + solar clip Daytime Planets
Astro
Visible + near-infrared broadband
The workhorse for nighttime deep sky imaging. Passes the full visible spectrum plus near-IR, capturing natural colour from a wide range of objects. Best for galaxies and reflection nebulae. Works for emission nebulae under dark skies but Duo-Band is preferred from light-polluted locations.
Galaxies Star clusters Reflection nebulae Dark skies
Duo-Band
Hα 656.3nm · OIII 500.7nm only
Narrowband filter passing only two emission lines. Dramatically reduces light pollution and moonlight. The best filter for emission nebulae from suburban or moonlit skies. Will suppress galaxies and reflection nebulae — their signal is broadband and gets blocked.
Emission nebulae Supernova remnants Light pollution Moonlit nights

Understanding EQ Mode

The Dwarf 3 is physically an Alt-Az mount — it moves on altitude (up/down) and azimuth (left/right) axes. The problem with Alt-Az tracking is field rotation: the star field slowly rotates relative to the sensor during long exposures, causing stars near the edge of the frame to trail in a curved arc. At exposures under 15 seconds this is usually acceptable, but it becomes significant at 30 seconds and above.

EQ Mode compensates for this in software. After calibration (which requires the unit to be accurately levelled), the Dwarf 3 adds a counter-rotation to cancel field rotation, effectively behaving like an equatorial mount. This allows clean, round stars across the entire frame at 30–60 second exposures.

Under 15s
Alt-Az fine
Field rotation is minimal. EQ Mode not required, but harmless if on.
15–29s
EQ Mode recommended
Edge stars begin to soften. EQ Mode improves results noticeably.
30s and above
EQ Mode mandatory
Field rotation will visibly affect the stacked result without EQ Mode.
Mosaic mode
EQ Mode required
EQ Mode must be active to unlock mosaic mode regardless of exposure.

First Night Tips

🌡

Let it acclimatise

Put the Dwarf 3 outside 20–30 minutes before imaging. Thermal equilibrium between unit and air reduces internal thermal noise and prevents lens fogging.

📍

Level carefully

Good levelling is the foundation of accurate EQ Mode calibration. Use the phone's built-in level app or a bubble level before starting your session.

🌙

Start with Auto Parameters

For your first session, use Auto Parameters — it handles exposure and gain automatically and caps at 15s, which works without EQ Mode. Learn the app before tweaking settings.

🔆

Choose a bright target first

Start with the Moon, the Pleiades (M45), or Orion Nebula (M42). These give fast, satisfying results and let you learn the workflow before attempting faint galaxies.

💧

Watch for dew

In humid climates, dew can settle on the lens within an hour of a session starting. Check the lens periodically — a fogged lens produces soft, hazy images. A dew shield or heater helps.

🔋

Use a power bank

Battery life is ~5.5h in astro mode. For long sessions, connect a USB-C PD power bank to run continuously. The Dwarf 3 can be used while charging.

🎯

Target altitude matters

Aim to image targets above 30° altitude. Lower targets pass through more atmosphere, increasing blur, colour distortion, and light pollution impact.

More frames beats fewer longer subs

100 frames at 30s beats 30 frames at 60s for most DSO targets. The stacking algorithm improves SNR with √N frames — keep sessions running and build frame count.

🖥

Infinity Lab for processing

Dwarflab's built-in Infinity Lab tools (Mega Stack, Stellar Studio) let you enhance images without external software. Stack multiple nights of data together using Mega Stack for significantly improved results.

⚠ Safety — Solar Imaging

  • Never point the Dwarf 3 at the Sun without the Dwarflab magnetic clip-on solar filter securely attached. Permanent sensor damage and eye injury can result.
  • Always attach the solar filter before powering on and selecting Solar mode.
  • Inspect the solar filter before each use — a scratched or damaged filter must not be used.
  • Keep the lens pointed away from the Sun at all times while attaching or removing the filter.
