| Comment : |
This was the first astrophoto of this season.
I didn't even had time to polar align or focus correct.
Comet Leonard can be as bright as magnitude 4, when I took this photo the magnitude was maybe 5.5.
I can very sad about where I live, Bortle class 9 !
We have just come home from Fuerteventura, Bortle class 3. |
