The Dwarf Mini is the right starting point if you want to try astrophotography without spending more than £400, and without committing to a complex traditional setup. It makes sense if:
The Dwarf Mini is not the right choice if you want the highest resolution images in the DwarfLab range, or if the wide-angle all-sky capability of the Dwarf 3 appeals to you. For those priorities, the Dwarf 3 is the better option.
The Dwarf Mini uses a single 50mm f/5 telephoto lens — the same optical specification as the Dwarf 3's main lens. This means the core imaging capability is identical: the same focal length, the same aperture, the same field of view on the primary target. What changes is the sensor and the absence of a second lens.
The Sony IMX462 sensor in the Dwarf Mini is a well-regarded 2.1MP CMOS chip, used in astronomy cameras at higher price points. It performs well in low light, which matters for deep-sky imaging. The trade-off compared to the Dwarf 3's IMX678 is lower resolution and less fine detail in the final stacked image — you'll see the Orion Nebula clearly, but with less fine structure than the higher-res sensor can reveal.
There's no wide-angle lens. You can't simultaneously capture an all-sky view or run an Milky Way timelapse alongside your main target. If those use cases matter to you, the Dwarf 3 is the model to buy. If you simply want a straightforward single-target smart telescope experience, the Dwarf Mini does the job cleanly.
The Dwarf Mini's 50mm aperture and auto-stacking firmware handles the same range of targets as any compact smart telescope. These are the highlights:
The Orion Nebula (M42), Lagoon Nebula (M8), and Omega Nebula (M17) are accessible from suburban skies. The structure is visible; finer detail benefits from darker conditions and longer stacking runs.
Andromeda (M31) is the showpiece target — the elongated core and dust lanes are identifiable with a good stack. Smaller galaxies like M81 and M82 in Ursa Major show up from darker sites.
Open clusters like the Pleiades, Beehive (M44), and Double Cluster in Perseus are quick wins on any clear night. Globular clusters like M13 in Hercules resolve into a dense ball of stars.
Lunar imaging is one of the Dwarf Mini's strongest suits. Craters, mountain ranges, and the curved limb all photograph well. A full-Moon session is a satisfying first test for new owners.
Saturn's rings and Jupiter's main cloud belts are visible. A 50mm aperture isn't a planetary specialist, but the results are more than just a dot — especially at opposition.
When a bright comet comes through — and they do — the Dwarf Mini's tracking and stacking makes comet imaging straightforward. One of the more satisfying things a compact smart telescope does well.
7 reviews at First Light Optics — a smaller sample than the Dwarf 3, but the sentiment is consistently positive. Key themes from verified buyers:
Genuinely easy to use from the start. First-session success is a recurring theme. The DWARF app guides you through alignment and target selection in a way that doesn't require any prior astronomy knowledge.
Portability is the standout feature. Buyers specifically mention taking it out on garden chairs, balconies, camping trips, and holidays. The lightweight build and long battery life make it a take-anywhere option in a way that most telescopes are not.
Good enough for social sharing and prints. Results from the IMX462 sensor are sharp enough to share — multiple buyers mention posting their first nebula or galaxy image online to positive reactions.
DWARF app is polished and regularly updated. DwarfLab continue to push firmware and app improvements post-launch. Some early software limitations reported in older Dwarf II reviews have been addressed in the current generation.
A compact aluminium tripod designed for both the Dwarf Mini and the Dwarf 3. Adjusts from 25cm to 53cm via 5 twist-lock leg sections, with a fluid head for smooth repositioning. At 790g folded to 25cm, it travels well. The Dwarf Mini's own stand works on flat surfaces; this tripod gives you flexibility in the field. A sensible addition if you plan to use it away from a garden table.

The Dwarf Mini is the entry point in a three-way comparison. The DwarfLab Dwarf 3 (£465) adds a higher-resolution 8.3MP sensor and a second wide-angle lens for all-sky capture — if those features matter to you, the £86 step up is worthwhile. The ZWO Seestar S50 (£539) takes a different approach: same 2.1MP sensor as the Dwarf Mini, but with a built-in dual-band narrowband filter that transforms nebula imaging from light-polluted locations.
For a first smart telescope, the Dwarf Mini gets you the full experience at the lowest cost. If you know light pollution is your main obstacle and nebulae are your main target, the S50's filter makes a strong case for spending more from the start.
