Description

After seeing Jean-Marie's image of large sunspot groups on the sun, I decided to take follow up images later in the day. I recorded three 20-s videos at about 60 fps to get 3600 frames in total. I stacked 30 best frames from the total. I used a ZWO 1.25" H-alpha filter to diminish as much as possible the effects of the seeing, which was mediocre because the sun's altitude was relatively low. From left to right the sunspot groups are AR2786 and AR2785. After a very long time, the sun's activity certainly seems to be increasing!
