Money no object....hmmm.
I'd buy Hubble off NASA & the ISS, just for weekends of course & if anything broke I'd dump a truckload of cash on NASA's doorstep & say "FIX IT, don't bother me with the details just do it".
But more realistic would be one of those 32" RCOS jobbies stuck on a mountain in the Atacama desert....300 clear nights a year you say Mike...Noice one.
