LOFAR-VLBI wide-field image of the central region (size 9.2′×7.5′) of A2255 at 144 MHz (from Fig. A.2). The final image has a resolution of 1.5″, with rms noise of 38 μJy beam⁻¹. The restoring beam is shown in the bottom-left corner. Top panel: Zoom on the Original TRG with the main features labeled as in Paper I. The contour levels from the sub-arcsecond resolution image from Paper I (Fig. 4 in that paper) are drawn in red at the 3, 9, 27, 81, 243σ levels, with σ = 18 μJy beam⁻¹.
