May 8th. This image shows sunspot groups AR2057 & 2055 (upper left) and AR2056 (lower left), on the eastern side of the Sun. Single exposure image with a Canon 550d camera, through a Baader wedge at 540 nm and WO 81 mm refractor. Compare this to my image of proms in the same region in Halpha light (other post). Cheers and thanks for viewing.
