While I was setting up focus and exposure for my ISS transit images, I shot a few still images. The ISS flew by a rather large sunspot group AR2585. This is the best image I had of the sunspot group:
Questar 3.5" with Sony a6300 at prime focus. 2016-09-04 19:15 UT. Best exposure of 55 1/250 sec at ISO 200. Deconvolved in Lynkeos. Cropped and exposure adjustment in Photoshop.
