Color gri-band composition of the region containing Cloud-9. The SDSS image is shown with a zoomed-in HiPERCAM ultra-deep image centered on Cloud-9. Scattered light from the bright star HD 111859 (V = 8.09 mag), located just outside the HiPERCAM field of view at bottom left, affects the lower-left corner of the ultra-deep image. No stellar emission is detected at the location of Cloud-9 down to 31.4 mag arcsec⁻² (g-band). Increased noise at the image edges, caused by the large dithering pattern, appears as a whitening of the background.
