Startrails from a Small City (~7000 citzens), but with lots of public ilumination! The light pollution was very bad due to 2 street lamps near the location, plus 2 enormous lamps lighting up the Forum of the city. Overall the image turns out to be better than expected, although far from perfect. Taken from MG, Brazil. Thanks for seeing.

Startrails de uma pquena cidade (~7000 hab.), mas com muita iluminação pública! A poluição luminosa estava péssima devido a 2 postes de rua próximos ao local, mais 2 holofotes iluminando o Fórum da cidade. No geral a imagem saiu melhor que esperado, embora longe de ser perfeita. Tirado de MG, Brasil. Obrigado por ver.

*Processing note: Stacked using StarStax in the Lighten Mode. Blended it with a single frame taken a few minutes later, in order to show the "static" stars in PS CS2.*
