z′ filter images of the 10 exoplanet host stars for which new companion candidates have been detected with the exception of HAT-P-35, for which the i′-image is shown. The grey scale is proportional to the square root of the count. To improve the visibility of the close companions to HAT-P-27, HAT-P-28, HAT-P-35, WASP-76, and WASP-103, we additionally applied unsharp masking. The orientation is identical for all images with north up and east to the left.
