Christmas Conjunction: Jupiter & Moon




I just finished to process the images I took last night of the Jupiter-Moon conjunction. It was a bit cloudy over here but I managed to get a glimpse of the event between the clouds. The scene was already impressive with the naked eye but the view through the eyepiece was absolutely amazing! It's not everyday that one can see the belts of Jupiter and the craters on the Moon in the same field of view! The biggest planet in the Solar System and the biggest object in the night sky side by side. A Christmas to remember!

"Blue Moon" selected for LPOD! (23/Dec/2012)

Dear friends,
I am glad to announce that my image of the fenomenon "Blue Moon" was selected to LPOD (Lunar Photo Of the Day) on the December 23rd. It is the 3rd image of mine selected for LPOD by Charles Wood.

"Charles Wood, a former NASA scientist who had studied the Moon and writes a monthly lunar column for Sky & Telescope, proposed starting the LPOD as an adjunct to his NASA-funded web site www.observingthesky.org. (...)
LPOD is based on the very successful Astronomy Picture of the Day, which contains a wonderful picture and brief caption each day with links for further information. APOD is viewed by millions of people around the world. It has sparked a wider interest in astronomy and the new understanding that comes with the beautiful images. (...)
All of these PODs provide an easy and quick way for astronomers - both amateur and professional - and the general public to stay in touch with emerging science and be awed by the beauty of the cosmos." - from LPOD website.

It's been a while...

...since I took my SPC900NC out of the box for some Solar System imaging. One day before opposition, I caught the King of Planets and two of its wonderful moons. The telescope wasn't properly collimated and seeing was poor...nevertheless, I am glad I spent a couple of hours outside looking through the eyepiece and to the screen with Jupiter dancing in the turbulence.
Note: It was freeeezzziiiiiinnngggg COLD! x)

Blue Moon

Canon 1000D, 250mm, 1/200s, f/5.6, ISO100.
 
"Ontem (31 de agosto de 2012) foi dia de Lua “Azul”, mas o nosso satélite natural não ficará, de facto, com cor azul.
Este nome serve apenas para designar a segunda Lua Cheia que ocorre no mesmo mês, algo se só se repete a cada 2 ou 3 anos. Isto porque o período sinódico da Lua (isto é, o tempo entre duas Luas Cheias consecutivas) é de 29,5 dias. Por isso uma Lua “Azul” só pode ocorrer em meses de 30 ou 31 dias (nunca em fevereiro), e a primeira tem de ocorrer no dia 1 ou 2 desse mês.
Esta definição de Lua “Azul” só começou a ser usada em 1946, já que a definição mais antiga definia a Lua “Azul” como a terceira de quatro Luas Cheias na mesma estação do ano (normalmente, por causa do período sinódico, só há 3 Luas Cheias em cada estação).
A raridade das luas azuis está na origem da expressão anglófona “Once in a Blue Moon” (traduzido literalmente, “uma vez a cada Lua azul”, o que significa um acontecimento raro).
A Lua “Azul” seguinte ocorrerá no dia 31 de julho de 2015."

Martian triangle and the Moon at the beach

I returned to the beach after the Sun went down to capture this awesome conjuction: Moon plus the "Marian triangle" formed by Mars, Saturn and Spica. The view at the beach was breathtaking! Canon 1000D, 30 sec, 400 ISO at Manta Rota, Algarve, Portugal in August 22th, 2012 at 22 pm.
