Centre of the Abell 2764 cluster. Extended emission in the form of shells and stellar streams is traced in the NIR (colour image with I_E-band in blue, Y_E in green, and H_E in red) down to 27.0 mag arcsec⁻² in the H_E-band for a direct visual detection of physical features, such as a stellar stream, at 1 σ at the single square arcsecond scale. Structures within these faint features are well defined. The field size is 7ʹ by 3ʹ.5.
