What was your most memorable astronomical, OBSERVATIONAL, telescope event? For me, it was seeing Jupiter with all four Galilean moons, circa 1967. It blew-away the mind of this (at the time) 9-year-old amateur astronomer. I was hooked, instantly. Thank You, Maker Of All Things. I was nine years old, IIRC. 18th Avenue in SLC, on the back balcony of my best-friend in 5th grade. Good people, they don't know what they truly did for me. I am humbled at their generosity. (A secondary shout-out goes to the late Gene Roddenbery. Star-Trek actually spurred my astronomy interest, as did the US manned space program...yes, I got to see Neil Armstong step on the moon in real-time in my parent's living room. WOW!) Number two was seeing Saturn's rings, probably within a few months of my Jupiter revelation. :-) And you? :-)
