Zoom-in image of the central region in the ELAIS-N1 field, created from an 8-hour observation using the international LOFAR telescope at a frequency range of 120-168 MHz. This region is centred at (16h09m01.36s, 55m19m56.7s) and is 0.3 deg × 0.3 deg in size, with a resolution of 1.2″ × 2″. The colour bar represents the flux density from −2σ to 20σ, where σ = 0.122 mJy beam−1 is the approximate RMS noise in this region of the image.
