OBJECT DESCRIPTION AND IMAGE SESSION

NGC 6541 was discovered by Italian Astronomer Niccoló Cacciatore at the Palermo Astronomical Observatory in Sicily in march 1826. In July 1826 it was independently found by James Dunlop.

The globular is 13 billions years old and has a spatial diameter of 100 light years across. It contains approximately 150,000 stars. Photography wise this object is often overlooked due the magnificent Corona Australis Nebula Complex, however its a nice globular to photograph even from light polluted skies as my home backyard in Buenos Aires Suburbs. It can be seen with binoculars however it appears as a hazy glow about 3 arc minutes.
