Stargazing in Quebec 🔭

An Ash-Dome installation in Quebec brought advanced astronomical observation to the province—supporting science education, public outreach, and sky-watching through the seasons.

Built to withstand the snow, wind, and cold of Canadian winters, this dome offered a reliable home for research and inspiration alike.

Decades later, the Quebec observatory continues to stand strong, reminding us that exploration starts with the right foundation—and the right shelter.

Precision. Durability. Discovery. That’s the Ash-Dome legacy.

At Ash-Dome, every observatory dome starts with precision. Our standard sizes begin at 8', then continue from 10'6" up to 30'6" in two-foot increments, giving you the flexibility to build the observatory you’ve always envisioned.

Domes from 8' to 16'6" are part of our Model R family. Domes from 18'6" to 30'6" make up our Model M line.

Two models, one purpose: dependable performance for generations of sky-watchers.

These early photos from our archives shows the craftsmanship that built the Ash-Dome legacy. Each panel was hand-measured and aligned with precision to ensure a perfect curve and smooth rotation.

Before digital tools, it was all skill, geometry, and dedication. Those same principles still guide every dome we build today.

🔧 Built to last. Built for exploration.

Precision Engineering, Elevated — Literally 🏗️🌌

In Utah, a 24.5’ Ash-Dome was assembled at ground level and lifted into place as a single unit. The perfect fit on the first try shows the power of teamwork and precision engineering.

Why this matters:
🔧 Every segment fits seamlessly
⏱️ Installation is efficient and minimizes disruption
🌄 Built to endure harsh, high-altitude conditions
🌌 Enables discovery for decades to come

Each dome we build is more than a structure. It is a gateway to exploration. Watch the full installation video here: https://www.youtube.com/watch?v=cLOv2VPRVx4
