Question: Regarding Stellar Spectroscopy Equipment.

Click For Summary
SUMMARY

The discussion centers on the calibration challenges faced by an applied physics student using an SBIG ST-7 camera with a DSS-7 spectrograph for deep space spectroscopy. The user reports that the captured spectra are misaligned, with blue wavelengths appearing on the right and red wavelengths missing. The recommended solution includes contacting SBIG for technical support to resolve the alignment issue and improve the visibility of the full spectrum.

PREREQUISITES
  • Understanding of spectroscopy principles and applications
  • Familiarity with CCD imaging technology
  • Experience with SBIG ST-7 camera operations
  • Knowledge of calibration techniques for spectrographs
NEXT STEPS
  • Research SBIG ST-7 camera calibration techniques
  • Learn about DSS-7 spectrograph alignment methods
  • Explore troubleshooting steps for CCDops ver. 5 software
  • Investigate common issues in deep space spectroscopy equipment
USEFUL FOR

Applied physics students, amateur astronomers, and researchers involved in spectroscopy and astronomical imaging who seek to optimize their equipment setup and calibration processes.

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!

I would suggest contacting SBIG themselves. They should be able to help you figure this out.
