Stellar Spectra (L)

1987
We study reproductions of spectra, recorded at the Michigan Observatory. Handle these spectra carefully. Orient the violet side to the left, the red side to the right. Where necessary, use a magnifier; it has a plane-convex lens: turn the convex side towards your eye, bring the eye quite close to it.
