Bonner Durchmusterung (BD)
The great pre-photographic survey of the northern sky, carried out under Friedrich Argelander at Bonn and published from 1863. It recorded positions and magnitudes for about 325,000 stars to roughly ninth magnitude — the most comprehensive star catalogue of its era — and its 'BD' designations remain in use for naked-eye and telescopic stars today.
