So if you're lucky enough to be in the zone of annularity, the Sun's bright ring will average 1 arc minute wide.
Abell 2 in the heart of Cassiopeia, for instance, has a total light equivalent to a 14.1-magnitude star, but its tiny compact disk gives it a surface brightness of magnitude 12.7 per square arc minute. Also, depending on the strength of its emission lines, a very dim planetary might jump out when you employ the right filter.

The comet's magnitude, however, is called "total visual magnitude" which ICQ describes as magnitude integrated over an observed coma diameter of several arc minutes. This means a seventh magnitude comet is more difficult to see than a seventh magnitude star, with the latter having all its light in a pinpoint while the former having the same amount of light spreads out over a large area, the ICQ explained.
