  Reflection nebula is gas only lit up by nearby stars. It should not be mix up with emission nebula, where hot stars nearby cause the gas glow. But then reflection nebulae are visible in the same areas with emission nebulae. The appearance of reflection nebulae is irregular, and many of them need bigger instruments to be visible.
  
  Reflection nebulae are glowing blue around the stars of Pleyades. Image Juha Parvio.
  
  The blue glowing reflection nebula NGC 1333 around the bright star is in Perseus. Image Timo Inkinen.
  
  The bluish reflection nebula NGC 2023 is located lower left from the Horsehead Nebula. The Horsehead Nebula itself is a dark nebula in the front of red emission nebula IC 434. In the left side there is NGC 2024 aka Flame Nebula. Image Samuli Vuorinen.
  
  NGC 7538 in Cepheus is a combination of reflection and emission nebula. Image Timo Inkinen.
