Radio images of the source NGC 6086 at 144 MHz (top row), 400 MHz (central row), and 675 MHz (bottom row). The left column shows images at the highest resolution (8.37 × 5.22, 8 × 5.5, 4.8 × 3.7 arcsec, from the top to the bottom panel, respectively) and the right column at low resolution (30 arcsec). Contours are drawn at (−3, 3, 5, 10, 20, 30) × σ in the first panel; (−3, 3, 5, 20, 50) × σ in the fifth panel; and (−3, 3, 5, 10, 20, 40, 80)  ×  σ in the other panels. The ‘×’ markers in the panels in the right column indicate the position of the host galaxy. The beam is shown in the bottom-left corner, and a reference physical scale is shown in the top-left one.
