An observatory dome serves as protective armor for precision instruments. It shall deliver unobstructed all‑sky field‑of‑view while resisting wind, rain, snow, extreme temperature, hail and seismic activities. The 3.5‑meter all‑sky astronomical dome developed by Sky‑Shine Optoelectronics is engineered for research observatories, campus observatories and outdoor photovoltaic instrument protection, integrating robust mechanical structure, electromechanical actuation and remote‑control capability.
The dome features a maximum outer diameter of 3.5 m with lightweight overall design, total weight ≤ 1400 kg. Movable shell panels adopt 2.5 mm fluorocarbon‑coated aluminum sheets, while the fixed base skin uses 2 mm stainless steel. Its design service life reaches over 20 years for long‑term outdoor deployment.

⚙️ Outstanding Environmental Adaptability
- Operating temperature range: ‑40℃ ~ 60℃, suitable for both frigid and torrid regions
- Seismic fortification intensity Grade‑8; wind resistance up to Grade 12; normal opening/closing available under Grade‑6 wind
- Hail‑resistant exterior; snow‑load capacity for 500 mm maximum snow depth; reserved lightning‑protection earthing terminals
- Fully weather‑proof sealing when closed to prevent rainwater ingress into equipment compartment
📡 Electromechanics & Intelligent Control
Opening and closing time ≤ 1 minute respectively, operating noise ≤ 60 dB. Driven by four 220 V motors with chain transmission. Dual‑limit protection and emergency‑stop switch are equipped. Manual operation is available during power failure.
The control system supports local‑priority plus remote operation. General‑purpose interfaces including TCP/IP Socket and RS232 are provided, compatible with Windows & Linux OS. Real‑time status feedback enables unattended automatic observation workflows.
🚚 Transportation & On‑site Assembly
Modular split‑body design fits inside a 40‑ft standard shipping container. Only riveting assembly is required on‑site; no on‑site welding or painting. Assembly can be finished within two working days under favorable weather conditions, shortening project lead‑time significantly.
Built‑in access door and rear equipment storage compartment facilitate personnel access and instrument storage. The dome can be integrated with telescopes and imaging devices from mainstream brands including Lunt Solar Systems, ZWO, QHYCCD, CELESTRON and Sky‑Watcher for complete observatory turn‑key delivery.
Ideal for university research stations, educational observatories and outdoor optoelectronic instrument shelters. 📩 Contact us for full technical datasheet and project proposal.
