I recently completed a DIS run observing the Jupiter/Io system, switching between spectroscopy and narrowband imaging. The run was very successful - even including 'objective grating spectroscopy' as a test of narrowband bandpass. Special thanks to Camron & Russett for making it come together. I wanted to make sure that in discussions of grating choices for DIS2 that the mirrors remain available. The rapid switch from imaging to spectroscopy is a unique capability and should be preserved. I'd appreciate email from other users who use this capability or have advice on the matter. cheers- Nick Schneider (CU) APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 91 in the apo35-dis archive.
