The SE200 Echelette Spectrograph was build by Optomechanics Research of Vail, AZ. It has a spectral resolution of about 15 km/s (R~20000) and covers the entire visual range in the atmospheric window from 350nm - 1000nm in a single shot. This instrument is our main workhorse for spectroscopy on the 20-inch telescope.
We are not using the software sold with the SE200 because it was primarily suited for lab bench spectroscopy. We use MAXIM-DL to run the CCD camera and reduce the spectra with home-grown software.
CCD Camera
The CCD camera on the spectrograph is currently an SBIG STF-3200EN purchased in 2021. Prior to 2021, the camera was an Apogee Alta U32 purchased with the spectrograph in 2006. The same grade 1 CCD has been used in both cameras.
