When collapsing to a white dwarf, a red giant Sun would emit a planetary nebula. How far from the Sun would that nebula stretch at most?

Also: At about what distance could you see the planetary nebula completely in all its beauty, I mean so that the entire nebula would match into your eye's field of view? The Earth and Mars would be deep within the nebula I guess, as well as the main asteroid belt. If you watched the Sun from Eris' aphelion or Sedna's perihelion, I guess that would be best to observe the entire nebula or ain't I correct? And what would the nebula look like from Proxima Centauri b?

In other words, how close to the Sun's planetary nebula can you be and still see it entirely in its beauty?

    $\begingroup$ Nebulae don't have clear borders. They are made out of the particles. The density is the biggest at the center and falls to the "edges". You should specify the density of the matter at the edges, for example, to give us enough information. $\endgroup$

    $\begingroup$ I edited your title and retracted my close vote, but please consider to update the body, understanding the answer, too.

You question has now 2 close votes as "opinion based", edit it to ask for a so objective answer as possible. $\endgroup$
