Saturn with the shadow of Titan

On January 23, 2025 at 7 pm I tried to capture the planet Saturn low on the western horizon and with a really bad seeing. The image is therefore not very sharp, but you can still see the shadow of its satellite Titan as a dark spot in the southern hemisphere of the planet.
