Details:
I attempted an experiment, as suggested on SpaceWeather a few days ago, to observe these famous giant sunspots in projection. I decided to use a small toy telescope, with features comparable to Galileo's (in this case, a 35 mm lens, about f/10) but of slightly superior optical quality, which came with some issues of the comic magazine "Topolino" for the International Year of Astronomy in 2009. And after a few attempts, taking advantage of some clearings between the clouds, I managed to capture a decent image of the Sun. Experiment successful! Bottom right, image captured with a Canon 60Da + 300 mm. zoom lens and solar filter in Astrosolar with poor seeing and among the clouds.
