For a long time I was able to describe this time I was in Ruissalo, Turku. There was also a small cloud, but they also quickly passed.

      Dark nebulae are dust in space. It obsruct the visibility of background star and bright nebulae. Thus, the dark nebulae are seen as dark clouds in space.

    • Emission nebula info

      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.

Oikein hyvä kuva. Onko yksittäisvalotus vai pino? Autoquidaus?

Santeri Peltola - 19.11.2017 at 10.03 Report this

Kiitos :) Otin 25 kuvaa joista 16 kuvaa oli sellassia mitkä kone pinosi pixinsight ohjelmalla. Autoguidausta en käyttännyt jalustan oma seuranta pysyi suht hyvin paikallaan.
