Magnification versus Resolution


  High magnification with reduced field of view.
 This is from a high quality ground based image here displayed overly magnified.
 It is possible to increase the magnification until your eye can pick up
 the finest detail in the image. 
 Further magnification causes loss of field with no greater resolution.

  High resolution with wider field of view.
