It might not be well-known, but Dobsonian telescopes CAN be made to track the sky by using a device known as an equatorial platform. 

These are available commercially and instructional videos for use and construction are available on YouTube. 

Dobsonian users don’t have to be limited to obtaining only bright star spectra!
