There are small specks visible on the image. That is from dust and detris on the sensor itself. Normally they aren't visible, as they specks are very very small, but at such a tight aperature all kinds of wonky diffraction effects can happen.

Pinhole
Our son, Sasha. I am currently experimenting with home-made...err..."custom"...lenses. This was taken with a pinhole, effective aperature of about f/600. Like any camera obscura, there is no focus ability, although I am attempting to marry the pinhole with a cheap old EF-mount lens to see if some sharpness can be obtained. What I really like about the experiment so far is the coloring.
