Morphology

nonstellar = stellar (transparent) = non + stellar

A straightforward negative formation: 'non-' negates 'stellar', so the meaning is directly derived from the base adjective.

Etymology

Nonstellar combines non- ('not') with stellar ('star'). Because stellar is used for both things about stars and for things that are 'excellent', nonstellar means either 'not related to stars' or 'not outstanding in quality'.
