M42 - 5.2.2016 at 23.35 Kauhava Observation number 48824

Visibility IV / V

Oskari Syynimaa, Lakeuden Ursa

Orion's large gas mist had to be photographed again. This time, the exposure accumulated for a total of 54 minutes with 60-second partial exposures, so the accuracy of the tracking was put to a tough test. Although light pollution bothered, so much became apparent. :)

      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.
