Working out from Nasmyth:
* "Inside" Nasymyth is autoguider. This can patrol half of the field of view, and will hopefully have a focus mechanism.
* Nasmyth mounting plate will have:
** James to provide details of this mounting as used on Wide Field Camera on opposite port.
** 1/4 of the field of view will be for a High Resolution Spectrograph (HRS) fibre feed
