LIGHTS color composed images of NGC 4321 (21.5′×21.5′, left) and NGC 5866 (15′×15′, right). NGC 4323 (in possible interaction with NGC4321) is marked with a green circle. The color composed images are constructed by combining g (blue), r (red) and a linear combination of the two ((g+r)/2, green) using Gnuastro's astscript-color-faint-gray (Infante-Sainz & Akhlaghi 2024).
