Memorial Day Monday and the clouds are variable.  A high layer of Cirrus clouds reduce the light coming from the sun and the first time in a while, I had to increase my exposure time to get my favorable histogram.  Here another image of the sun wit AR1224, 25, 26, 27, 28 as well the inverted processed image.  AR1226 has been very active as it was yesterday.  Yesterday I also made some close-ups of 1226 and some promenances, however the images made with the 5x barlow generated heavy streaks in even light processing, so I am not putting them up here, but I wonder why this is happening.
