Astro

The Ring for a Full Moon

The International Year of Astronomy

International Year of Astronomy 2009 Logo
400 and a half years after Galileo Galilei peeked into the heavenly moon with his telescope, a fake astro fan like myself decided to take more steps into his astro life by subscribing 3 years of the politically correct Astronomy magazine and a Canadian-favored SkyNews magazine.
The next step would be saving $3000+ to actually get a nice astrotelescope...so sit tight for my upcoming astropictures (in the next 400 years?).

Orion's Cradle

The Great Orion Nebula (aka M42 or Messier 42) is one of the most famous nebulae. It is to us the closest star forming region diffused with atomic hydrogen gas. Adding to its fame, it is also the brightest nebula viewed on the Earth, even visible to the naked eyes in a clear night sky. This picture is taken with Pentax 67 165mm lens at f/4, SBIG STL-11K camera with hydrogen-α filters that adds the pervasive red colour, reflecting the long wavelengths of the emission lights due to electron-atom recombination during the star forming process.

A Cerro Tololo Sky

"The CTIO 4-meter Blanco telescope, silhouetted against the Magellanic Clouds (at left) and the Milky Way, as seen from Cerro Tololo in Chile. This is not a composite image. It was taken by Roger Smith using a 2048x2048 scientific CCD which has much higher sensitivity than photographic film, revealing greater detail in exposures short enough (20 seconds) to eliminate star trails. The CCD, normally used on the telescope pictured, was temporarily mated to a Zeiss Distagon 40 mm f/4 lens by a "camera body" made in house. The only source of illumination is starlight."
