Pleiades |
oc |
TOB_R-50f4 |
The naked eye can see 6, possibly 7, stars in Pleaides, arranged roughly in the forma of a tiny dipper. Even a small telescope will greatly increse the number of stars visible, up to limit of mnore than 100. Wisp of nebulosity cover the group, especially bright in the neighborhood of the luminous stars. The nebulous backgraound show cleary on long-exposure photographs, but you will probably not be able to see it visually. The star cluster is 430 light-years away | ||

The Hyades contains fewer stars than the Pleiades and also is less compact. Use low power to see this extended V-shaped group, wich forms the head of Taurus. The Hyades are approximately 130 ly distant. | ||

Althoug the star shows cleary on most photographs, so much of this light falss in the ultraviolet that the central star is visible only with largest telescopes. The atoms of the nebular gas absorb energy in the far ultraviolet and convert it to visile radiation, so that the gas becomes luminous. A 4-inch telescope will reveal the nebula cleary, though still larger one are necessary to show structural details. This nebuloa, is also known as M 57. | ||
