NGC206 is an unusual object. It’s a cluster of stars, which in itself is not unusual at all… but it’s in ANOTHER GALAXY. The Andromeda Galaxy, to be precise. The fact that we can see it so clearly, two and a half million light-years away, boggles the mind.
It’s that cluster of blue stars near the center of the image. In all, there are about 300 of them, thought to be about 10 million years old (that’s actually very young, as stars go!)
It’s within a spiral arm of Andromeda; the galaxy itself is far too big to fit into one frame with my telescope. It’s yet another example of the amazing things in the night sky that are just a little too dim for our human eyes to see unaided.
