He was a fast learner and soon was allowed to observe with all the instruments. His favorite telescope was one with a 3° field of view. (This suggests a magnification around 15×.) Pons was known to possess an extraordinary ability to remember the star fields he had observed and thus to recognize changes within them.

In 1813,...
