IC 1848 - 14.9.2021 at 22.30 Ulvila Observation number 101261

Visibility V / V

Vesa Puistovaara, Porin Karhunvartijat

Now came a great opportunity for me to try shooting nebula for the first time, so it didn't help that much else - I had to try it!

The beginning went quite well, taking hydrogen pictures, but as the subject slowly climbed towards the zenith, stock problems began to hit my nerve cells. - color images were not taken ...

On the other hand, I only caught hydrogen pictures, and I also got them commendably ... once again I have to be quite happy with this output too :)

-maybe later the colors will be found in this sample (?) -

      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.
