L1SQM 21.9
Bromo Caldera
East Java · 2329 m
Our base camp. The caldera floor blocks valley light, leaving a clean horizon in every direction.
Network — Our dark-sky sites
Seven places we keep watch.
We grade every site with a sky-quality meter and revisit it through the seasons. The map plots each one by how dark it gets and how open the horizon is — the closer to the centre, the darker and clearer.

Distance from the centre is darkness; the line threads the sites into a single constellation. The gold point is base camp at Bromo.

Every site,
in detail.
Each photo slot below is where a real shot from that location will go.
L2SQM 21.6
Ijen Plateau
East Java · 1850 m
High, dry and far from any town — the pre-dawn sky here glows with the faint cone of zodiacal light.
L3SQM 21.7
Sembalun, Rinjani
Lombok · 1156 m
A wide valley under Rinjani’s shoulder, with an open southern horizon for deep-south targets.
L4SQM 21.8
Komodo Outer Isles
NTT · sea level
No mainland glow for a hundred kilometres. The sky meets the sea in a full, unbroken arch.
L5SQM 21.4
Dieng Plateau
Central Java · 2093 m
Cold, high volcanic terraces. Bitter nights here reward you with some of Java’s steadiest seeing.
L6SQM 21.3
Belitung Coast
Bangka–Belitung · sea level
Granite boulders and shallow water make a natural mirror for the rising summer Milky Way.
L7SQM 21.5
Wae Rebo Ridge
Flores · 1100 m
A remote highland village with zero light pollution — the most atmospheric night on our roster.
