The sun today through the hydrogen alpha Lunt solar scope.
This is a 35mm dual etalon filter solar scope.
Photo taken at 1/60th of a second handheld with canon t1i Eos camera.
Altered slightly with curve filter bringing up RGB mid tones a bit and sharpened slightly. (program app is called Filterstorm for iPad.)
The faint curved pattern that looks like a wave shadow on the left side is artifacts from the RGB color sensor in the camera. A monochrome image sensor would not show those false patterns.
The rest is pretty close to what was visible, but detail in the scope was better for those who saw it in person.
We had six classes of thirty students visit today during the day.
The first two classes were not able to see the sun because of clouds however.
