Unknown objects

  The red line through a star like point is not likely to be a galaxy, I suppose, as spiral arms are not red.
  The green fuzz and a red dot near the lower bright star are what??

  Hi eugenius and welcome to MWP.

  The red line is probably an artifact. But galaxies do appear red in these image, see the guide for some examples : Guide

  the green fuzz and the red dot near the star are also optical artifacts.
