This morning I used the wonderful program BackyardEOS to capture the images and was attempting to utilize the frame and focus feature...so in addition to the 2x magnification of the barlow, I was using the 5x magnification of the software. It was an exercise in atmospheric turbulence! The Sunspots were large on the monitor and went from fuzzy to sharp to fuzzy so fast I was amazed. In any event, below is a full disc taken without the barlow and a crop of the barlowed image containing the large spot region 11543.
