Lee, the idea of space expanding is indeed weird. It seems caused by "dark energy" but that's a term attached to a total mystery. As for telescopes, glad you have a 10-incher. What's in the photo is my old C-5 that I sometimes use when I need portability. My main observatory instruments, pier-mounted, are a research grade f/6 refractor, with a Takahashi 5-inch refractor mounted piggyback. About 130 pounds to drive, with another 130 pounds of counterweights! Love talking shop!
