Solar Imaging Session - September 22, 2012 ( Nice AR11575 Sunspot Group)

The sky this morning was partly clear to my surprise so I didn't waste time to image right away the Sun. AR11575 Sunspot Group is large and nice to view both in white light as well as Ha wavelength. AR11576 Sunspot Group, on the other hand is moderate in size but is inconspicious in appearance. There is also a large, wide hedgerow prominence visible in the SE limb as well as a large arching dark filament beside AR11575 Sunspot Group.
