Hi, I am new to this forum but I am an applied physics student and I'm working on a seminar on deep space spectroscopy. My question is actually on the equipment being used for my research. I am using an SBIG ST-7 camera with a DSS-7 spectrograph and I've been running calibration studies with element lamps to gather reference spectra for elements such as Argon, Helium, etc.. However when I capture the spectra with Ccdops ver. 5, the spectra is shifted to the far left (i.e. the "blue" wavelengths appear at the right hand side of the spectra) and from the middle to the left is all dark space so I'm not seeing any of the "red" wavelengths. I was curious to see if anyone had any suggestions on how to align the spectra with this equipment so I can view all of the spectra. All suggestions are appreciated!
