== Introduction ==
This is the current user manual for SpUpNIC (Spectrograph Upgrade - Newly Improved Cassegrain), the recently upgraded spectrograph at the 1.9-m telescope's Cassegrain focus. See the [https://topswiki.saao.ac.za/images_topswiki.saao.ac.za/3/3e/SpUpNIC_2016.pdf '''SpUpNIC paper'''] presented at the 2016 SPIE Astronomical Telescopes and Instrumentation conference in Edinburgh for more information about the instrument, and please cite the '''[[[SpUpNIC refereed science paper]]]''' published in the SPIE Journal of Astronomical Telescopes, Instruments and Systems.

The spectrograph's collimator and camera optics have been replaced, the instrument has a new detector, all of the mechanisms are now under PLC control and the software (both for instrument control + quick-look data reduction) has been completely re-written. There is also a rear-of-slit camera that makes it easier to acquire targets and focus the telescope properly.
