M42 - 13.11.2021 at 00.00 - 13.11.2021 at 02.00 Järvenpää Observation number 102319

Visibility IV / V

Eemil Pietilä, Ursa (Etelä-Suomi)

Orion's Nebula ST80 through my telescope. I removed the stars with a software called Starnet ++ to get the halos removed more efficiently. I did well, at least in my opinion. I will put a link to my previous observation so you can compare.

      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.
