  In an emission nebula the hot stars nearby cause the gas glow. This should not mix with reflection nebula, where the gas is only lit up by nearby stars.
  
  The appearance of a gas nebula is irregular, and the fainter parts of it need bigger instruments to be visible.
  
  Emssion nebulae in Cepheus. The bigger part is composed of the nebulae Cederblad 214 (Ced214) and NGC 7822. The lower round nebula is called Sharpless 170 (Sh2-170). Image J-P Metsävainio.
