Doug is right. Imagers take LOTS of images and stack them together to get more detail with each image. In this process images that are affected by bad seeing are dumped so only the good ones are stacked. With each layer more of the constant signal is added and the noise from seeing effects and from the chip are reduced finally producing a very detailed image.

Our poor old eyes can only use the image that is presented to them at the time.
