DIY All-Sky Detection System: Pan/Tilt Rig, Spectroscopy, and Crowdsourced Observation of Unusual Sky Phenomena

To the point

French hobbyists built an automated sky‑watching setup that uses a rotating pan/tilt disco‑light rig with a camcorder and CCTV camera, plus a diffraction grating to spot bright emission lines, so they can continuously scan for unusual lights, compare video from multiple angles with GPS‑timestamped data, and weigh the trade‑off between covering the whole sky and getting clear images, while noting it could capture satellites, meteors, or unexplained phenomena and could be expanded with more sensors to help science.
