C78 소개

설명

NGC 6541 is a bright globular cluster in Corona Australis, about 22,800 light-years away. It is a moderately concentrated cluster spanning about 13 arcminutes with an integrated magnitude of 6.6.

관측 팁

Visible as a bright, round glow in binoculars. A 6-inch telescope begins to resolve the outer edges at 100x+. An 8-inch scope provides a fine view with many stars resolved around a dense unresolved core. Best in summer from southern locations.

역사

Discovered by Niccolb Cacciatore in 1826 from the Palermo Observatory in Sicily. It is one of the nearer and brighter globular clusters in this part of the sky.

재미있는 사실

NGC 6541 has a low metallicity, indicating it is one of the older globular clusters in the Milky Way, formed early in the galaxy's history when fewer heavy elements were available.
