The 2.16-m telescope is located at the Xinglong Observatory (China). It used to be the largest optical telescope in China and even in the Far East. The 2.16-m telescope, with a 2.16-m effective aperture, has Cassegrain and Coude focuses, which is simple to change to each other (only needing one minute). The 2.16-m telescope equipped with the BFOSC (Beijing-Faint Object Spectrograph and Camera), OMR Low Resolution Spectrograph and HRS (High Resolution Fiber-Fed Spectrograph), is able to do a variety of research with complete functionality. The full technical instructions can be found here.
For the next observational campaign, the GRANDMA team has obtained allocated time on the 2.16-m telescope for GW optical counterparts. It will be utilized to confirm and to follow up the candidates of optical counterparts with imaging and spectroscopy.
