You know, there are only a handful of working professional astronomers in the world. It's not a large workforce. And then there are lots of amateurs that pursue astronomy for the sheer pleasure of it. And most comets discovered these days are named for the amateur(s) that discovered them.
And really, finding a comet on a dark night, in the exact location where there was nothing visible the night before, is something like making a good street photograph. The odds are against it, but it's thrilling when it happens. And the truth is that most amateur astronomers and street photographers are in it for the process, not the end result. We're having a good time, and we don't believe it's all been done. And even if we did, we would still make photographs.
