'Hidden' lenses

  • angelam by angelam

    When looking at a simulated (or other) lens in a galaxy on quick dashboard 'bluer' - like the one in the top right hand corner of this image - whether or not I see the 'blue' lens against the spread of 'blue' stars surrounding the galaxy can depend on the angle of the laptop screen which affects the contrast. I frequently 'see' false positives or miss lenses that are there! But I simply don't know how to be more accurate.
