Quit Sun

Today we had an open and clear sky and thus more then 14h time to observe the sun. Observations were done using my PST40. It was a quit sun without sunspots and two small prominences of which one was more bright then the other one. Both are located at east of the sun (location 4h).

Picture was taken afocal with 8-24mm lens on 24mm. Editing completed using CS4.
