Description
View of a model designed by Piazzi Smyth to demonstrate the use of his instrument for observing zodiacal light. The author describes its purpose in the accompanying text: “The mode in which...errors are to be detected by Astronomical observation, and how corrected, may be shown in a model which I have had made, and of which a drawing is appended representing an Equatorial of the ‘English’ construction...placed within a rude resemblance of the celestial sphere...”
Illustration from the unpublished paper "Attempt to apply instrumental measurement to the zodiacal light...”, by Charles Piazzi Smyth. The paper was written or completed on 25 March 1848 and received by the Royal Society on 13 April. It was eventually withdrawn on 2 November 1848. It contained an appendix, from which this illustration is drawn: “Appendix...describing a simple equatorial instrument, adapted to and sufficient for its measurement.”
Inscribed in ink below: “Model, explanatory of the adjustments of the equatorial instrt.”
