Heliotrope (parts)
notes: label: Description
content: When new, this instrument probably consisted of a refracting telescope surmounted by a round mirror that could reflect a beam of light along the optical axis of the telescope. With a screw base, it could be attached to a tree or post. Fauth advertised a heliostat of this sort in 1877, describing it "As made by us for the United States Coast Survey." New, it cost $30.
