I took this picture last week, in Alto Paraíso - Brazil. The nebula was next to disappear behind the horizon, but i could take 13 good shots before the atmosphere get to strong.
For the picture, I use the folowing equipment:
Telescope: Orion Premium ED 102mm
Mount: Celestron CG5
Câmera: Canon 550d (T2i) unmodified
Alignment: False polar star made with a green laser.
Stacking: Deep Sky Stacker 3.3.3 (with 10 dark and 15 flat frames)
I hope you like
