The Palomar 200-inch f/9 Cassegrain CCD camera
This article describes the design and construction of a CCD camera for the f/9 Cassegrain focus of the 200-inch (5 m) Hale Telescope at Palomar Observatory. This instrument utilizes a set of 18inch (0.45 m) diameter lenses to change the Cassegrain focal ratio from f/16 to f/9, and the optical design prescription of these lenses is reported. For CCDs having 24zm pixels, the f/9 focus gives a rec...

The sensor can be operated in its default mode or programmed by the user for frame size, exposure, gain setting, and other parameters. The default mode outputs an SXGA-size image at 30 frames per second (fps). An on-chip analog-to-digital converter (ADC) provides 10 bits per pixel. FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a pixel clock that is synchronous with...
