Imaging Processing
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.
