New Horizons is going to be launching a Parallax Program this year - with planned simultaneous observations from Earth and New Horizons of Proxima Centauri and Wolf 359 on April 22nd and April 23rd.

At New Horizons distance the change in position for those two will be very noticeable - over an arcsecond - and the combined 3-d image should have some noticeable "pop" for those two stars versus other background ones.

As always this decade, the latest photo ever taken by New Horizons will be the Farthest Ever Taken.

What I meant is ask amateurs to image given patches of sky as NH does the same, then do blink comparisons ...a pure fishing expedition. Low probability of success, but this might uncover nearby objects like small red & brown dwarfs with very low proper motion relative to the Solar System as well as extremely long-period TNOs.

Again, super long-shot stuff.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
