Heart mist shot with dual-narrowband filter and color camera. The stars are from the data recorded with the light pollution filter a year ago: they are not very satisfied with them, but the colors were better than with the narrower filter.

Observation target
- Deep space object
Designation
- IC 1805, IC 1795

Nebulae
- Emission nebula
  
  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.
  
  The Orion nebula. Image Samuli Vuorinen.
  
  In this 4-degree-field there are emission nebulae Sh2-157, Sh2-158, Sh2-159, Sh2-161 and Sh2-162 (or NGC 7635 aka Bubble Nebula) and open clusters M52 and NGC 7510. Image Juha Kepsu.
  
  NGC 281 aka Pacman Nebula. The object is in Cassiopeia. Image J-P Metsävainio.
  
  NGC 896 in Cassiopeia is the tip of Heart Nebula (IC 1805). Image Timo Inkinen.
