Details:
Sunspot AR2786 is so big that at sunset (precisely 10mins before sunset) I saw it with completely naked eye (no optics, no filter, no camera), thanks to a bank of low clouds (and to mist) acting as natural filter. The photos, shot at around the same hour with a unfiltered telelens, try to convey the feeling. The "natural filter" clouds are seen in image2 on the lower half of the Sun. Visually the Sun was pink, still blinding, but I saw the sunspot within just a second of observation, which was safe enough. It was this way, using mist or clouds, that astronomers in past centuries were able to witness sunspots without any technology. Of course the big sunspot is seen easily without optics also at day with clear sky, using a filter like eclipse goggles.
