Sunspot Group 1176

Being I have been having some bad luck lately photographing nighttime objects, I thought I would turn my attention again to our daytime star.  Group 1176 is now near the center of the disk, and I was able to readily see it with it projected onto my posterboard.  As the last time, I simply photographed the posterboard with the sun's projection on it.  I used the 25mm eyepiece on the 70mm refractor to get the following photos:
If you look around the disk, there are some other irregularities, possibly some other spots, but I could not bring them out well enough, and besides, they could be dirt on the optics.  Its difficult to tell with the sun.

I also processed a closeup image of the group:
This was taken from the same image as the first.

Not too shabby using projection.
