Hi Luis,

Excellent report Luis --well done. While the shadow of Io on the Jovian cloud-tops is very small, it is equally very high contrast and that is the major reason it is visible in fairly small apertures in good seeing. Same goes for the Cassini division between the A and B rings of Saturn -- mind you, you need the rings a bit more open than at present.

Felicidades y un amigo bien hecho !



Best,

Les D
