Poker Digital All-Sky Camera(PKR DASC)
• Developed by KEO scientific• Andor IXON+ EMCCD
– 1k x 1k pixels
– 16-bit digitization
• Telecentric optical system with filter wheel
• First deployed Sep 2007– Unfiltered for 07/08
• Typical operations is three-filters – 427.8 nm, 557.7 nm, 630.0 nm at a 12.5 sec cycle time

All-sky Meridian Spectrograph “Digital MSP”
• Refurbished in 2009 as part of MSP upgrade study
– Filter wheel removed– 600 line/mm grating replaces 1200
line/mm grating– 50 mm camera lens replaces 85 mm
lens– 200 => 500 micron slit
• Has now replaced MSP• 15 second sample rate
• 6 channel operation– 427.8 nm (N2+)– 486.1 nm (H+)– 520.0 nm (NI)– 557.7 nm (OI)– 630.0 nm (OI)– 670.0 nm (N2)
