The spectrograph attached to the telescope
subject: Observatory Hill, Plaskett telescope
description: A picture of the spectrograph that J.S. Plaskett designed attached to the telescope. Plaskett paid attention to the details of the design to make it as efficient as possible. Visible in the background are the two clocks used by observers. One kept normal time, the other sidereal time. The clock drive for the telescope is visible at the right
