H-Alpha sun

Along with astronauts, Novaspace Galleries had a 6 inch refracter from Starizona set up with an H-Alpha filter looking at the Sun. I used eyepiece projection, aligning my camera with the eyepiece, to take this image of the sun and some flares and prominances on its limb. The circular spot in the middle on the left is just a reflection from the optics. You can also see a little granulation on the surface of the sun itself. This image was take with the kit lens on my Canon 20D, the exposure was 1/200 seconds at f/5.6, ISO 400. Posted by Picasa
