Cosmic Photons Astrophotography : October 2015

Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

The Cave Nebula

The Cave Nebula ( Sharpless 2-155, Caldwell 9) is part of an extensive region of ionized hydrogen gas region. Sharpless 2-155 is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and associated with the Cepheus B giant molecular cloud, laying at a distance of about 2800 light-years. Part of the cloud is illuminated by a pack of hot, young stars known as the Cepheus OB3 association.

IC 1795

IC 1795 is an emission nebula located about 6,000 light-years away in the constellation Cassiopeia.
The dominant central star of IC 1795 is a blue dwarf on the main sequence. In addition there are three other stars of class O and B with ages between 3 and 5 million years. This being an age intermediate to the 6 to 20 million years of the shell structure that encloses the complex. The region is one of the sites most studied (besides Orion) for the formation of massive stars. This area is more dense and rich in H II. It is home to, and hides, a group of young blue stars, with their radiation ionizing the residual gas clouds. (WIKI).
