Description

After several months without any opportunity to take pictures, I had a clear night and tried a quick shot of this wide field. These 31.5 minutes are not enough for an uncooled colour sensor, nevertheless it was nice to capture it.
The tiny red dot on the left side (in the middle) is not an integration error, it is Kiso C6-87, a carbon star that I could identify thanks to the Aladin catalogue :

You need to see the full size version to detect it.Carbon stars are quite special, they contain more carbon than oxygen  and this provide a strong red colour. You can learn more about it here :

All the best,

Andreas
