Chromatic aberration, smc PENTAX 1:8 1000mm @ f/8.

Star in the Orion (point source). You are seeing individual pixels (highly
cropped).

This is why we shoot with filters, red, green & blue and focus for each one.

I don't like them myself. They're pretty bad.
I grieve over them long winter evenings."
