In this image the main structures of the mini-halo are identified as: the northern extension; the two eastern spurs; the concave edge to the south; and the south-western edge and a plume of emission to the south-south-west. The small knob at the end of the western tail is the galaxy NGC 1272. The bar at top left shows a distance of 90 kpc or roughly 240,000 light years.
