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)
