A nice cloudless early morning. The sun is kind of busy with active regions, but flare activity has been minimal. Since the seeing was a lot better(3) than earlier this month, today again a few images with the C11, the 3.8u WL filter, but today I used the red filter for three sunspots. The green allows shorter exposure time (1/10.000) but the red gives more detail. The three close ups are made with: 1) SM40 and a 3x barlow and 2)the C11 in prime focus, and the large scale image of 1806 uses an additional 2x barlow. I tried 1806 also with a 3x barlow, but the turbulence was too much to get any decent images.
