Deep Space Spectrograph

SBIG’s new Deep Space Spectrograph (DSS-7) is optimized for spectral observations from stellar classification to nebular analysis to galactic red shifts. It is optimized for the ST-7XME or the ST-402, and will work well with ST-8/9/10/2000 cameras and ST-237s. It will not work with the STL series due to their deeper backfocus required by the built in filter wheel.
