3 things

  1. What's with black dot in the middle? (It appears at many pictures)
  2. Is smaller yellow dot a star?
  3. Blue-green thing is a star too, right?

  1. the black dot in the center is an optical artifact, caused by the brightness of the core.
  2. smaller yellow dot is indeed a foreground star
  3. blue/green dot is also a foreground star
