OBJECT DESCRIPTION AND IMAGE SESSION

 

Deep in the Southern Constellation of Musca (the Fly) we find magnitude 7.2 Globular Cluster which is blured by cold gas and dust particles of interstellar material. The mentioned is coming from the Dark Nebula known as Dark Doodad Nebula. The nebula was named some years ago by editor Dennis di Cicco after seeing an image he took from Alice Springs in Central Australia. This type of Dark Nebula does not irradiate any energy. It obscures the light coming from the stellar background covering a relative size of almost 3 degrees from north to south direction.

The nebula can be seeing with binocular from dark locations although it takes some practice to the eye and mind to note its contrast.

 

The picture was taken in a star party organized by Diego Hernandez and friends form  Aves Argentinas in the very nice Yamay Farm
