M16 - 27.8.2022 at 22.19 - 27.8.2022 at 23.04 Janakkala, Tervakoski Observation number 108975

Visibility II / V

Petri Kuossari, Riihimäen tähtit. yhdistys

On Finland's Nature Day, I photographed eagle fog on Vespera. The misty field and the starry sky created a wonderful atmosphere.

The colors of the first and second image have been slightly adjusted, the third image is unprocessed. I also added a minute-long video of the formation of the image on the tablet screen. Pretty quickly the M16 forms appear.

      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.

Kiva demo tuo video! Yllättävän vauhdilla se kuva vahvistuu, etenkin alkuvaiheessa.
