| Comment : |
This year I replaced my Canon 5D camera with a Canon 6D.
More pixels and lower noise is the main attraction for astrophotography.
At this place the light pollution is lower, a 40 km drive from home.
That is more important when photographing in the Northern direction from South of Stockholm. See also the time lapse video from the same photos: YouTube. |
