NGC 206

 

NGC 206 is a giant open star cluster located in our neighbour galaxie M 31, also known as the Great Andromeda Nebula. M 31, and hence NGC 206, are approximately 2.3 million lightyears from Earth.  It is amazing that today’s amateur technology allows us to resolve single stars within the spiral arms of M 31, while no more that some 100 years ago the biggest telescopes available were necessary to identify those brightest stars.

The image also contains plenty of tiny detail like a number of globular clusters of M 31 and several background galaxies. Make sure to see the annotated image.
