Well, as I said, I think I would get bored just staying in Peru for the rest of my life. My astronomy project may be the most important thing in my life at the moment, but it is not the only thing. If anyone else could understand that boredom with staying in one place I am betting it is other expats. You guys have probably lived in other countries besides Peru.
I would also like to spend time in Malaysia and Argentina. There are some things I like about each country, but I think the change of pace is the important thing. No matter how much I like a country I think the sameness of living in it every day kind of wears me down. I want a change of scenery from time to time. I guess I could move to a different part of the same country for some change of pace, but that wouldn't help in this case. I'd still be 'abandoning' my property.
My plan would be to have 2 or 3 homes. One in Peru because of the climate, the latitude (ideal for parts of my project), possibly the altitude (again great for my project), maybe the food, the easy language, no visa problems, relatively low cost of labor so that I can afford to hire people to help me.
Patagonia / Tierra del Fuego for the cold weather and change of seasons, probable good food, easy language and visa situation, as well as being one of the few places on the planet with a nice straight shot at Alpha Centauri, Epsilon Indi, and maybe LHS 288 and Gliese 832.
Malaysia, because I'd feel incomplete if I never stepped foot in Asia again, or never had a great curry again, and because the latitude is perfect for Procyon and and probably my only chance for 61 Cygni, and it's a chance to speak my native language for a while. It's also safe. I don't think anyone would mess with my dish while I was gone. Malaysia would be my northern hemisphere base.
The truth is I'm really not sure about Malaysia. I probably can't afford 3 bases anyway. It's just too expensive and too complex to manage. It would probably be better not to do astronomy in Malaysia. All that humidity, that water vapor is hell on microwaves. Maybe I should just spend a year there every 4 years as a kind of vacation. Get myself an apartment in Penang with a view of the sea and eat lots of curry and try to learn how to make it myself for my next 4 years in Peru and Argentina.
Our planet rotates only in one direction (assuming you ignore the precession of the equinoxes). So if I want to see everywhere in the sky I need a base at more than just one latitude. Luckily there is almost nothing of interest for my project in the northern sky. Pretty much just Procyon and 61 Cygni. If I found something of interest I would consider Finland or Norway, although that would present some pretty serious visa, money, and possibly language problems that I'd have to overcome, and there's only so much I can accomplish in one lifetime anyway.
Does that answer your question, whatever it was? What was it the British said about Americans? Ask a Yank for the time and they'll tell you how to build a clock. Or something like that.
