IntroductionThe Kast Double Spectrograph is used at the cassegrain focus of the Shane 3-m Telescope. It is two separate spectrographs - one optimized for the red, the other for blue - housed in a single structure and having some components in common. Each side offers a selection of dispersive elements for various resolutions and dispersions, and both are also capable of direct imaging over a limited field. Dichroic beamsplitters and separate CCD detectors allow simultaneous observations in red and blue. Both sides are operated from a single interface. A polarimeter is also available for spectropolarimetry observations.
During March 2009, a new motor controller system was installed for Kast which should be more reliable and robust. There is also new graphical user interface for motor control. All observers (new and experienced) must be checked out by a support astronomer (email@example.com) on the afternoon of their first observing night to be instructed on the new software and changes to the system.
