Comparing a cluster of stars to a luminous bunch requires the hearer to consider not the light of one star but the spatial arrangement of several points of light. If colour, proximity, and rounded form also matter, the likeness becomes a coordinated whole.
It is insufficient to name mere brightness as the point. The relation is between two clusters and their constituent arrangement. The hearer must therefore reconstruct the overall visual configuration.
The same comparison model can be familiar under a simple respect and remote or subtle when additional, carefully chosen restrictions are included.
