[QUOTE="Horoscope Fish, post: 714523, member: 13090"] I spoke with someone who does pretty serious astro-photography and got their input regarding your issue. They confirmed what you're seeing is moiré. Their first suggestion, after seeing the image you posted here, was to disable any Lens Correction profiles you might be using in Lr or Photoshop as this is a known issue when doing star trails. The long answer had to do with reducing high frequency Bayer noise which I really wasn't following and, frankly, made my head hurt.
