saw the shadow (Mississauga)

Viewed Jupiter in the C8. Vixen tracking was working fine. Despite the extreme cold.

Bumped to crazy high power. Immediately saw a black spot, Ganymede's shadow, on the same side as the two moons, Io and Ganymede. Up and to the left for me. Kind of sketchy view at the high magnification. Although the seeing was good. Dropped back to 222x and the view improved, the shadow spot was darker, better contrast. Almost at the edge of the disc.

Great view of the planet. Good detail on the surface of the planet. Wasn't expecting that.
