The sun

Cory Poole's timelapse of yesterday's annular solar eclipse using a Coronado Solar Max 60 Double Stack telescope and a GH2. The telescope has a built in notch filter that only allows light from the H-alpha line at 656.28 nm to pass through. This allows astronomers to see features from the surface of the sun. 

Cory will be posting photos from the eclipse to his website shortly. He has a beautiful collection of photos available. Check them out.
