The Moon is the most rewarding first target for any smart telescope — bright, detailed, and visible from suburban gardens. This guide covers every phase, the best features to target, optimal Dwarf 3 settings, and how to get the most from your data.
| Scenario | Exposure | Gain | Filter | Mode | EQ Mode | Notes |
|---|---|---|---|---|---|---|
| Full disc — quick look | Auto | Auto | VIS | Lunar | No | Auto Parameters work reliably here |
| Crescent — terminator detail | 1/250–1/100s | 10–30 | VIS | Lunar | No | Bright limb will be overexposed — expose for terminator |
| First / Last Quarter | 1/400–1/200s | 0–20 | VIS | Lunar | No | Keep gain low — the disc is bright |
| Full Moon disc | 1/800–1/400s | 0–10 | VIS | Lunar | No | Full Moon is very bright — shortest practical exposure |
| Full disc mosaic | 1/400–1/200s | 0–15 | VIS | Lunar / Mosaic | Yes (Mosaic) | Use Mosaic Mode for full disc at telephoto scale. EQ Mode required. |
| Earthshine (dark limb) | 1–5s | 40–60 | VIS | Astro / Manual | Yes | Expose for the dark limb — bright limb will saturate. Crescent phases only. |
| Time lapse | Auto | Auto | VIS | Time Lapse | No | 5–30 second intervals. Great for showing Moon moving across a fixed star field. |
The terminator (day/night boundary) is where all the shadow detail lives. Expose to retain detail there — the bright limb will often saturate slightly and that's acceptable. The app's histogram helps judge this.
At low altitude the Moon passes through more atmosphere, causing shimmer and colour fringing. Wait until it's above 25–30° for noticeably sharper results. At 53°N the full Moon in winter stays low — late spring and summer are better for altitude.
Unlike deep sky imaging where stacking is essential, the Moon is bright enough that a single well-exposed frame can be excellent. Stacking helps in poor seeing — the app's lucky imaging approach picks the sharpest frames. Use Video mode for best-frame selection on planetary and lunar detail work.
Bring the Dwarf 3 outside 15–20 minutes before imaging. A warm scope in cold air creates tube currents that blur the image — the same applies to lunar as to deep sky. Especially important in Ireland where the temperature difference between indoors and outside can be significant.
At the telephoto focal length (150mm), the Moon doesn't quite fit in one frame. Mosaic Mode stitches multiple adjacent frames for a full disc image. EQ Mode must be active. This gives a significantly more detailed full disc image than a single frame at the wide-angle lens setting.
Deep sky stacking can overcome moderate turbulence. Lunar detail work cannot — atmospheric shimmer directly limits resolution. The best lunar seeing at 53°N typically occurs in late spring and early autumn when temperature gradients are minimal. Check seeing forecasts on Meteoblue or Clear Outside before a detail session.
The terminator crosses each feature at a slightly different illumination angle each month due to lunar libration. Tycho at day 7 after new moon in January looks different from Tycho at day 7 in July. Revisiting targets is always worthwhile.
The DWARFLAB app's Infinity Lab tools handle basic lunar enhancement. Stellar Studio applies sharpening, contrast, and colour adjustments to your stacked result. Sufficient for sharing quality output without any additional software.
For maximum detail, process the raw FITS files from the Dwarf 3 in dedicated software. Lunar images benefit from sharpening techniques like unsharp mask or wavelets which the in-app tools apply in a simplified form.
