Hi George,

The fits file is  2 column data table (wavelength and flux) not an image so Maxim does not understand it. You can view the data in a free general fits data viewer like NASA’s fv for example or alternatively download the dat file version and view it in notepad, excel etc.  Better though is to view it in a free dedicated spectroscopy program like Visual Spec or ISIS etc.  I have also loaded it into the BAA spectroscopy database so you can view it there too.
