Spectrum Image Information

• The stars are at spectral order zero and the horizontal lines on each side of the star are the spectral orders minus and plus one.
• The spectra at the blazed spectral order minus one is to the left of the star.
• The blazed spectral order minus one is brighter than the spectral order plus one.
• The very bright stars create dim spectral orders plus and minus two which start where spectral orders plus and minus one end.
• Both images north is top and west is right
  

Monitor Test Pattern

The following test pattern is to help you adjust your monitor to best view the CCD astro images. The test pattern is used for adjusting monitor brightness, and contrast. Adjust monitor brightness and contrast to see all 16 gray scale levels. The most important adjustment when viewing astro images is to see the differences in all of the black bands.
