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. http://www.bob.blakely.com/Chroma.gif ----- Bob, can you give us a link to a real star photo with that lens? (Not at Actual Pixels.) I'd like to see such, CA and all.
