My image of the Eastern Horizon (kind of, because up to about 15º it's obstructed by the nearby trees). The extremely bright Venus was really amazing that night (imaged with the Milky Way in my other image). Earlier that night (8pm) clouds rolled in. After got up at 3 o'clock in the morning, the sky was suberbly clear. I quickly set up the mount and camera, and tried to see/image the Zodiacal Light. It was visible, but, as a unexperienced observed (1st time seeing it), I think I could have framed it better/tried to find a better place with visibility on the Horizon.

I than started a time lapse sequence of the rising Venus, Milky Way, and Zodiacal Light. After 10 or so frames, a beautiful satellite crossed the sky and, luckly it went straight into the camera framing. As approaching Venus, it has noticeably increased in brightness (magnitude), until it finally disappeared. I didn't know what satellite it was back at that time. Afterwards, using Stellarium software, I discovered it actually was the Hubble Space Telescope (HST). All I could do was smile.

Taken from MG, Brazil (22º S), T4i with 18-55 at 18mm, f/4 and ISO 800. 90 seconds image. Thanks for seeing.

Minha imagem do Horizonte Leste (mais ou menos, pois até aprox. 15º o horizonte é obstruído pelas árvores próximas). O incrivelmente brilhante Vênus estava incrível naquela noite (fotografado com a Via Láctea em outra imagem minha). Mais cedo naquela noite (20h) nuvens fecharam o tempo. Depois de levantar às 3h, o céu estava incrivelmente limpo. Rapidamente montei a montagem e a câmera, e tentei ver/fotografar a Luz Zodiacal. Ela era visível, mas, como um observador sem experiência (1º vez que tento vê-la), acho que poderia ter enquadrado melhor/achado um lugar sem tanta obstrução.

Comecei então uma série de time lapse de Vênus, da Via Láctea e da Luz Zodiacal nascendo. Depois de aprox. 10 frames, um lindo satélite cruzou o céu, e, com sorte, ele foi direto para o enquadramento. Enquanto se aproximava de Vênus, seu brilho (magnitude) aumentou consideravelmente. Não sabia qual satélite era naqueles dias. Depois, usando o software Stellarium, descobri que, na verdade era o Telescópio Espacial Hubble (HST). Tudo que podia fazer era sorrir.

Tirada de MG, Brasil (22º S), T4i com 18-55 at 18mm, f/4 e ISO 800. 90 segundos. Obrigado por ver.
