Images of open star clusters
M45 - The Pleiades
M45 - The Pleiades
The Pleiades is an open star cluster located in the constellation Taurus. M45 is quite bright and can be seen with the naked eye, even from an urban location.

Starlight reflecting off the dust around the cluster forms a reflective nebula. Although the cluster is visible with the naked eye, the nebula is not. To pick up the nebula you need a telescope or very good binoculers.

IC1848 - Cluster in Cassiopeia
IC1848 consists of a number of star clusters surrounded by a faint nebula known as the Soul Nebula. Due to the short exposure time, this image does not show the nebula, but the tight star clusters inside the nebula are quite visible as can be seen from the close up below.

Open clusters are local groupings of stars found inside our galaxy that sometimes form interesting shapes and patterns. Some, like the Pleiades and IC8148 shown above have nebular characteristics as well.

Most open clusters can be easily spotted from the city even with a small telescope. Lots are binocular-friendly as well. The sizes and shapes range all over the map and they are usually among the best things to start with when you first get a telescope.
