Details:
This is a photo of Saturn now close to opposition which, in addition to its rings and some atmospheric bands, also shows some of the brightest satellites orbiting the planet and which are visible even with small telescopes. In this image the brightest satellite is Titan, then to the west of the planet Rhea and Dione are visible, to the east instead we have Tethys and the fainter Enceladus.
I had to do two shots with different exposure times to try to show the other satellites as well as the larger Titan.
During the night, the astronomical seeing was overall good, with moments of greater stability and sharpness when the planet was high in the sky.
