Bob asked:
"Anybody remember who said this (in regard to hand-made telescope
mirrors)? It's easier to make a 3-inch mirror and a 5-inch mirror, than
to make a 5-inch mirror."
I know this as referencing 6" and 8", which makes a whole lot more sense,
since a 3" mirror is tough to make (because it's small and fiddly).
I don't know who first said that, but
speaking as someone who built an 8" mirror first, I would have to say
they are probably right :-)
