Lobster Claw Nebula, Bubble Nebula, Northern Lagoon Nebula
Lobster Claw Nebula, Bubble Nebula, Northern Lagoon Nebula

Huge HII region in Cepheus and Cassiopeia. Massive stars illuminate surrounding gas clouds. Wolf-Rayet stars power the blueish central part of the Lobster Claw and a massive star blows up the bubble, which is nothing else but a shockwave generated by fast stellar winds. The open star cluster just on the top in the center has a funny form … like the tip of an arrow.

The region around Sadr or Gamma Cygni is full of emission nebula, dark nebula, star clusters, planetary nebula and all other sort of interesting objects. It is one of the most fascinating regions in our galaxy visible from the northern hemisphere.

NGC 6888 Emission Nebulae

NGC 6888

NGC 6888
NGC 6888

A gas nebula powered by a Wolf-Rayet star in the center. The star has ejected several times the mass of the sun into the surrounding gas remaining from the formation of the star only several million years ago. The star is more than 20 times as massive as the sun and has almost burned its fuel. In about a million years from now it will go supernova providing a spectacular firework.
