ATMOSPHERIC SEEING DEMONSTRATIO ... The following movie demonstrates "atmospheric seeing" using images taken 1/2-second apart with a 10-inch aperture telescope and a Nikon Coolpix 990 digital camera. There are 11 images, that repeat in a loop at twice the rate at which they were taken.

How atmospheric seeing affects telescopes with different focal ratios ... It is sometimes claimed that for telescopes of equal aperture, but different focal ratios, the longer focus instrument will perform better for a given atmospheric condition. Presumably, this is because the focus shift caused by the atmospheric cells...
