WHT f/11 Nasmyth focus

The drive side Nasmyth focus is occupied by the Utrecht Echelle Spectrograph. This has a dedicated A&G unit permanently mounted, thus access to this Nasmyth focus is limited. The GHRIL side Nasmyth focus can be used, although the positioning of the large optical table makes direct access to the Nasmyth turntable difficult.
