This site is for Astronomy Studies in the Tropics. I'm based in East Pattaya, Thailand, 12.934N, 100.918E, between the sun's northern limit and the Equator. The big advantage of this location is that you can observe both northern and some southern stars at the same time. And it's never cold... lol. I hope to introduce you to the unique celestial opportunities available from this area. Enjoy your observations!! Taro Seki Astropical.uk
