Anacortes Telescope and Wild Bird Picture of the Day February 22, 2010

Winner - Digital_Astro Monthly Challenge March 2010

This image nicely frames one of the most famous, and most recognizable, constellations in the sky -- Orion, The Hunter.

Across the center, you will see three bright stars that make up the "belt" of Orion. Hanging down from this are three "stars" that form his sword, though the brightest of these stars is actually the Orion nebula. Near the top, you can see two bright stars where Orion's shoulders would be. The large orange star near the top left is Betelgeuse. It is 640 light-years away, but is huge. If it were our sun, it would extend out beyond Mars! Near the bottom are two bright stars corredsponding to Orion's feet.

This is a very active region of space. The beautiful red emission nebulae surrounds the region. The half-circle of red nebulae to the left is Bernard's Loop. If you look closely, you can see two very popular imaging targets near the lower center, below Orion's "Belt": The Horsehead Nebula, and the Great Orion Nebula. I've imaged both of these with telescopes, so you can see what they look like close-up:
