Daneel Olivaw, featured in his earlier works such as The Caves of Steel and The Naked Sun, Asimov wrote this short detective story of an authorship dispute between two scientists.
Mirror A, the one used by Common, was installed in the telescope, while mirror B, also made by Calver, was sent to an optical firm in Dublin, Ireland, to be refigured.
Keeler also adjusted the mirror of the telescope so that its optical axis was accurately aligned with the center of the tube, and added a new low-power finder telescope, for picking the right area of the sky, to work with the existing high-power telescope.
The Newtonian flat mirror, which brought the light out to a focus at the side of the tube, was removed and, in its place, Perrine introduced a plateholder directly at the prime focus of the telescope in the middle of the upper end of the tube.
