Celestron has made a great many fine telescopes, but some models really stand out. The white-tube C5 is one of those. The optics are very sharp, and the portability is outstanding. Place the mount with its built-in wedge on a flat surface like a picnic table, orient it roughly north/south, and the built-in motor drive will follow objects in the sky faithfully for many minutes. The 9V battery will power it for up to 50 hours.
