Quote: From what latitude can [Alpha Centauri] be seen sufficient enough to be clear of the gunky atmosphere off the horizon and still be clearly resolved,in the northern hemisphere? Anybody tried this while heading south into Mexico from the U.S.?
I've seen Alpha Centauri from Querétaro, Mexico in the Winter (20.7° N latitude, 100.4° W longitude).
