Morphology
spectroheliograph = heliograph (semi-transparent) = spectro + helio + graph
The word is built by adding spectro- to heliograph, but the resulting astronomical instrument sense is specialized rather than fully predictable for an average learner.
Etymology
Spectroheliograph comes from three parts: spectro- ('light' or 'color'), helio- ('Sun'), and -graph ('to write' or 'record'), like in photograph. So a spectroheliograph is a tool that records the Sun in a single color of light to show special solar features.
