You're welcome, Rob
Took me a long time to get around to it, but I'm learning to "star-hop", and I can point to a bunch of stuff now that I only knew from photos, before...
I sorta knew "et" was just chain-yanking, but there's one thing astrology is good for, and I'm just learning that, too: it's a place to start from when teaching the sky to someone else. At least they've heard of some constellations.
What I meant about the history of science: way back in Babylon, astrometric observations for astrological purposes became the beginnings of modern astronomy.
