Details:
After glimpsing the large sunspot AR 2336 with naked eye through clouds on 7/10 evening, the following morning I imaged it with a 10" Newtonian telescope equipped with Baader solar film.
Interestingly, its penumbra structure was quite varied, consisting of thin, parallel filaments in some regions, and thicker, crosshatch-oriented ones elsewhere.
