Two (related) questions concerning spectroscopy: On the GRIM status page there's a note on spectroscopy which says one could select the f/10 slit with f/20 optics. Does anyone know how to do this? The Remark I/F just has one button for slit which presumably sets the optics as well. Also, if this can be done, would it be possible to get the larger (f/5) slit width with the higher (f/20) resolution? thanks, Bernadette Rodgers APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 28 in the apo35-grim archive.
