Low-density cluster NGC 376 in the Small Magellanic Cloud. (a): Pseudo-colour image obtained by assigning the RGB channels to the I, Hα, and V bands, respectively. The non-matching portions of the frame were masked. North is rotated 22 deg anti-clockwise from the vertical. The image spans about 160 arcsec on each side, which corresponds to a true size of approximately 48 pc at the distance of the SMC. The yellow rectangle highlights the area depicted in (b). (b): Higher-resolution rendering of the innermost cluster regions (credit: ESA/Hubble & NASA, A. Nota, G. De Marchi).
