Morphology

comatic = coma (semi-transparent) = coma + tic

Morphologically transparent (coma + -tic), but the meaning is a specialized optical term that may not be known to general learners.

Etymology

Comatic in optics comes from the same root as comet, from a Greek word komē meaning 'hair' that suggested a little 'tail'. So a comatic image looks stretched into a comet-like tail, which is why the word describes that kind of distortion.
