This is a photo of the total solar eclipse of March 9 2016, that I took in Sulawesi, Indonesia. The whitish hair-like structure around the sun is called the "corona", and it is formed by the hot gas particles (plasma) ejected by the sun into space (eventually forming the "solar wind").

The bright spot on the left is a solar prominence,

I used a regular DSLR camera (Sony A65) with a 300mm telephoto. No filter needed since this was taken during the moment of "totality", when it is safe to look at the sun with the naked eyes.

I took two photos with different exposure settings. The other photo is here.
