When I was in college, on top of the 19 story RLM (now PMA) building on the UT Austin campus, after a late night Astronomy Dept. viewing of the sky, we stayed around to watch the sun come up, to watch the end of the overnight eclipse of the sun end...
As we looked to the eastern horizon, the sky turned purpleish before the image of the sun first appeared.
That night was the first time I ever saw the rings of Saturn through a telescope (a Cassegrain).
Also, on the UT campus, I got to look through the Painter Hall 9" refracting Telescope as one of Jupiter's moons cast it's shadow, as it traversed across the face of the planet.
