Lucky Camera image of WASP-67. The image size is 45 × 45 arcsec² and is shown in a logarithmic flux scale with north up and east to the left. The FWHM of the image is . The triangular PSF comes from the telescope in very good seeing. The extra flux north-west of WASP-67 A is not a real contaminating flux source but an optical ghost from the star caused by internal reflections within the beamsplitters.
