IC 1805 - 4.12.2021 at 19.30 - 5.12.2021 at 04.30 Joensuu Observation number 103499

Visibility IV / V

Antti Taskinen, Joensuun Seulaset

Very few have had the opportunity to watch or photograph the starry sky in recent months due to cloud cover, at least in Joensuu. One clear night was in early December, I used it to photograph Heart Nebula (IC 1805). Fish head mist (IC 1795) was included in the picture as well.

EDIT: I was still working with the image data and I ended up with a slightly different color scheme and also a higher quality result in my opinion. I switched it to the main image and the second image of the previous version.
