HNA Spectrograph Stuff
The HNA spectrograph is a long-slit near-infrared spectrograph for the Palomar 200-inch telescope which, unfortunately, Has No Acronym. The HNA spectrograph was built by James Larkin and Rob Knop as part of their PhD thesis work at at Caltech.
Because I put a manual together for the PIFS, it made sense to make the appropriate modifications to form a manual for the very similar HNA. This page's primary purpose is to provide access to said manual.
