The image of the sun with a sunspot.

I made a quick solar scope with binoculars, a clamp, a cardboard shield, and a white paper screen. You can see at least three sunspot clusters that I confirmed are real using a real solar observatory website.
All this is practice for the transit of Venus that we will observe in Hawaii on June 5th. There will be much more professional observers there so this is my backup to the backup.
