Some images crops ,moire and aliasing

You can not get aliasing, nor can you get moire, with a single object like a twig. Neither can "jaggies" on a straight edge be called aliasing - although they are artifacts in their own special way.

So any object like a twig (or a star) that is in good contrast with it's surroundings will show up in the image, even it is less than one sensel at the image plane.

From the classic movie:

"What we have hyah is a failyah to communicate"
