Large sunspot gp.

5th Jan. Took two images of the sunspot group AR11944 this morning with rough air conditions. First is a Halpha shot thru a SMII60 mm scope, and second is thru a WO81 mm scope with Baader wedge. Both single exposure images thru a Canon 550d camera at about 10 am this morning. I measured the diameter of the largest spot in this complex group at 62,000 km. Thanks for viewing. Cheers.
