In stellar aberration, is there any prism effect, chromatic aberration?

  • $\begingroup$ I'd like to believe that it looks a little like this but of course it doesn't. $\endgroup$ – uhoh Dec 18 '19 at 16:12

    $\begingroup$ Since all wavelengths travel at the same speed in vacuum, at most the prism effect would take place in the portion of the path that's in our atmosphere. I suspect that will be a microscopic fraction -- consider the relative path lengths. $\endgroup$ – Carl Witthoft Dec 18 '19 at 20:16
  • $\begingroup$ @CarlWitthoft that's a really good point, why not write up an answer based on that? $\endgroup$ – uhoh Dec 19 '19 at 2:42
  • $\begingroup$ @uhoh I might -- but then I would feel it necessary to work the calculation :-) . (Yeah I'm feeling lazy this week) $\endgroup$ – Carl Witthoft Dec 19 '19 at 14:59
