Sirius

Visible with the naked eye
Jan 15 - Mar 30


Sirius, the Dog Star, is the brightest star in the sky. It is inherently very bright because it is very close to us, only 2.6 parsecs; but also it is inherently bright. It is actually a double star, but the second component is a faint white dwarf which can only be seen in a large telescope.

Double Cluster

Visible with binocular
Sep 01 - Apr 01

The Double Cluster in Perseus consists of two groups of young stars, with more than 300 blue-white super-giant stars in each cluster. They are easy to see in binoculars, though they are even prettier in a small telescope.

Galaxies M81 and M82

Visible with a telescope
Feb 15 - May 15


M81 and M82 are two relatively close and bright galaxies in Ursa Major. They are bright enough to be visible in binoculars, barely, but it takes a telescope to show M82's unusual shape.
