| Comment : |
I'm almost at the end of the list of comets that I left because it wasn't much to see.
Now I process them because it still a bit interesting to see what astrophotographing can be done from a high light polluted city.
The magnitude when I took this photo of the comet was about 12.
It's easy to find it but not on this low resolution image, it's in the center.
Look at next where it's zoomed in. |

Because of the comet's speed relative to the stars it ha been elongated.
The camera follow the stars, not the comet in this case. |
