Asteroid Toutatis to shoot past Earth

Observing

Many articles and books on observing refer to small, medium, and large telescopes, but what are the borderlines in objective size that define small, medium, and large?

Observing

I have quickly come to find out that my 3.5-inch refractor is completely useless on faint objects, such as nebulae, galaxies, globular clusters, and comets. Will they be well within my reach with an 8-inch telescope?

Science

I recently found out about a great meteor shower that occurred on November 14, 1833. What actually caused this great event, and is there anything today that compares to it?
