There are two spectra here for your consideration. The first is from a low resolution grism assembly. The second is from a Shelyak LISA spectrograph via a 16″ SCT.


Image Details:This image is a single ten second image using the Rainbow Optics transmission grating threaded into the CFW-8 filter wheel. MaxImDL was used to take the image and process the data. Calibration was done using VSpec software. August 29, 2001.
Imager:SBIG ST-7 CFW-8 This was taken through a Tak FSQ-106n using a grism.

The spectrum below was taken through a 16″ SCT using a LISA spectrograph. It is a combination of 3×120 second integrations. Processing was done in Demetra.
