  The "second ring" is the two spiral arms going all the way round to make a ring.

  There's something odd about this one when looking at Skyserver (don't worry, I classified the image shown, not skyserver).

  

  Is that blue line related to the galaxy? Photoz of that line sugests that they are close together, but the color is completely different.
