In this very dusty section of northern Cepheus lies the star forming region NGC 7129 - a vast collection of gas and dust that is cavitating due to the stellar winds of the hot young stars that have blinked into existence in it's core. The central stars are about 1 million years old - veritable newborns in the grand scheme of things.

The cluster to the lower left is NGC 7142. This cluster is about 6000 light years distant, while the nebula, NGC 7129 is a mere 3000 light years away.
