Timelapse of interstellar comet 3I/ATLAS +background stars in Ophiuchus from 16x1-minute exposures last night (1m Jacobus Kapteyn telescope on La Palma through SARA remote ops). Unlike bound outer solar-system objects, most of its apparent motion is intrinsic, not reflex of Earth orbital motion.🔭☄️
