July 11. A fairly large sunspot is currently crossing the sun (AR 2665).
I managed to get 2 pics today. The yellow one is at 540 nm and the orange one at 656 nm (Ha). Both single exposures thru different telescopes using a Canon 550d. An extra pics has been added - this shows the sunspot as on 15th July (moved across the sun's surface) and July 17th (about to disappear).
Thanks for viewing.

Nice. Just had a look through my Aldi $99 cheapie solar scope, not as good as your image but worth a look. Thanks for posting.
