After dodging clouds and hailstorms all week I was able to record my first solar image at the CaK wavelength... 393.37nm in the violet end of the spectrum. I see almost no detail visually due to my eye's poor sensitivity at this wavelength. But the camera sees good!

This image was featured as NASA's Astronomy Picture of the Day on May 20, 2013. Some additional recent images with the Coronado CaK telescope can be seen here.
