I went to the River Ridge Observatory Saturday morning to image the Sun. The seeing was supposed to be very good and I’ve learned to shoot the Sun early, not just for the seeing but because it gets hot. It was already 86F when I left just after 9AM and 90F in town when I got there. These are sunspot groups 3712 (upper left) and 3713 (lower right) and they are quite large though there’s nothing to show scale here. This is the best 500 of 1000 one millisecond images stacked and processed. For once, I was able to bring out some of the granularity of the chromosphere.
