Product Description

SBIG's Deep Space Spectrograph (DSS-7) is a spectrograph optimized for the types of spectral observations that an amateur has always been interested in, from stellar classification to nebular analysis to galactic red shifts. The DSS-7 is a lower cost alternative to the SGS. The DSS-7 is actually more sensitive than the SGS making it excellent for Deep Space objects. It does not self-guide and it has slightly lower resolution than the SGS. It is optimized for popular Schmidt-Cassegrain telescopes but can be used on any system with an f/10 focal ratio. It is ideal for deep space objects such as galaxies and nebula. It will not work with the STL series due to their deeper backfocus required by the built in filter wheel.
