I'd like to believe that it looks a little [like this](https://scifi.stackexchange.com/q/85643/51174) but of course it doesn't.

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.

@CarlWitthoft that's a really good point, why not write up an answer based on that?

@uhoh  I might -- but then I would feel it necessary to work the calculation :-) . (Yeah I'm feeling lazy this week)
