H I detections in the Abell 194 field, with contours showing the H I column density (0.25, 1, 4 M_⊙ pc⁻² levels), overlaid on DSS1 optical images. The H I resolution is 19″ × 14″, p.a. 147°. Top: full cluster region showing more than 25 H I detections. Bottom: zoomed-in view of the boxed region from the top panel, showing the richness of resolved structures. Both bound H I and that in the process of being stripped from galaxies are evident. The compact H I source at RA = 01^h25^m47^s, Dec = −01° 22′18″ is Minkowski’s object, shown also in Fig. 1D.
