Cadwell 10 (NGC 663) and Open Cluster and Be stars
The Open Cluster known as C10 or NGC 663 is about 2100 parsecs from us towards the constellation Cassiopeia. Its estimated age is around 20 million years. Therefore its main sequence B2 stars are coming to the end of their life cycle. It is of great interests to astronomers due to its large number of Be stars. These stars are interesting due to the strength of their emission lines and their typical infrared excess. Here I present an RGB image composite of this cluster as taken from my telescope at the Vazquez Astronomical Observatory. Just another wonder in the Universe at the reach of us here in Webster, NY.
