OUTPOST 3M - Computerized clamshell dome for telescopes and space monitoring
OUTPOST 3M is a fully opening, 3-meter diameter computerized dome designed by PrimaLuceLab for telescopes and space applications. Unlike traditional observatory domes that require synchronization between the telescope and the dome shutter, OUTPOST 3M opens completely, giving telescopes unrestricted access to the entire sky. This makes it the ideal solution not only for astronomical observatories but also for fast-response tasks such as satellite tracking, space debris monitoring, and all-sky surveys.
Product Details
Constructed with a multi-layer GRP (Glass Reinforced Plastic) structure and featuring anodized aluminum and stainless steel components, the OUTPOST 3M delivers enhanced rigidity and durability, ensuring long-term stability even in the most demanding environments. High-speed motors and advanced remote-control electronics guarantee rapid opening and closing, while a selective shutter mode allows partial opening to protect the telescope from strong winds without sacrificing visibility.
Developed as part of PL Observatory Stations, OUTPOST 3M combines professional-grade reliability with an affordable price, making it suitable not only for research institutes, universities, and space economy companies, but also for advanced amateur astronomers and schools seeking a higher-quality solution. By merging robustness, automation, and affordability, OUTPOST 3M sets a new standard in all-sky domes for telescopes.

ALL-SKY OPERATIONS AND APPLICATIONS
The fully opening design makes OUTPOST 3M ideal for projects where speed and sky accessibility are essential. Research institutes and universities can use it for wide-field surveys and astrophotography, while companies in the New Space Economy can rely on it for satellite tracking, space debris monitoring, and quick-response observations. Scientific museums and educational organizations also benefit from its design, which creates an engaging and immersive experience for the public.
OUTPOST 3M is equipped with high-speed motors and advanced remote-control electronics that ensure rapid opening and closing operations, minimizing time to target acquisition and observation. Its selective shutter function allows partial opening, providing extra protection against strong winds while still enabling the telescope to access the required sky region. Fully automated and reliable, the dome is designed to operate seamlessly with robotic telescopes and remote observatory stations.

OUTPOST 3M - Computerized clamshell dome for telescopes and space monitoring: Safety features
OUTPOST 3M is equipped with custom-designed electronics by PrimaLuceLab to guarantee maximum safety and instrument protection. In case of a power supply interruption, the dome can automatically close even when it is not connected to any control software, as long as it is powered through a supported optional UPS (not included with the dome). Furthermore, OUTPOST 3M electronics can be connected to an optional rain sensor. In this case, the dome will automatically close when rain is detected, independently of the software used, protecting the instruments from sudden weather changes. This ensures a reliable safeguard for telescopes in all situations, including fully automated or remote operations.
