Visual Comet Hunting it was a rare year that did not bring forth several comets discovered by amateur astronomers systematically sweeping the skies with wide-field telescopes or large binoculars. The typical magnitude of these comets at the time of their discovery was between 8 and 10, relatively bright on the scale of telescopic objects.

Toward the Modern Understanding of Cometser than completely torn away. The nature of these strange objects appeared to defy a simple explanation. They clearly were not solid bodies, like the planets, nor were they similar to the Sun and other stars. Even though the heads of some comets looked relatively dense, the fact that stars were most

The Value of Visual Observing in a Photo-Happy Worldd are very relevant in the case of comet observing. For one thing, visual observations link today’s comet observers with the line of their predecessors stretching back to the days of ancient China and Greece over 2000 years ago. Only by comparing visual descriptions can we relate the appearance of a
