Astrophotography by Mario Cogo

 Grayscale

 

 

Adjust the brightness and contrast controls of your monitor so that you can easily see each of the 17 grayscale steps from black to white. 

If the strip appears to have a color tint , then adjust your color monitor's balance. 

 

 

Thanks to Chuck Vaughn and Jerry Lodriguss for this method of monitor calibration.
