Some nice sunspot groups developing at the moment (March 12).
The image shown is a single exposure one taken thru a William Optics 81 mm scope with Baader herschel wedge (operating at 540 nm). Canon 550d camera and 1/320 sec and iso200. The largest spot is AR11692, the group above it is AR11696 which just appeared today. :)
