NOTE: The offered "duplicate" question IS NOT WHAT I AM ASKING. Alternative methods of navigation ARE NOT ACCEPTABLE as answers. I am specifically asking whether or not a ship traveling in the method described could re-identify the destination star on approach because the perceived light of the star with each jump is "aging" as the ship approaches the "current age" of the star. Don't let @SlowlySwift's obsession with navigation fool you (he deleted his answer) and don't let the reason why I'm asking the question distract you.
In the future, humanity develops what we'll call "hyperspace technology." Basically, a starship can "jump," whether it be via wormhole or any other fanciful idea, from one location to the next a considerable distance away in a very short period of time from Earth's frame of reference. Please accept this as a given. The technology and the rules of that technology are not relevant to the question.
A ship decides to travel from Earth to a world eight-billion light years away. From Earth at the time the ship is launched, we're seeing light that's been in transit for eight-billion years.
The ship must make 100 jumps to get from Earth to that distant world (an arbitrary number for the purpose of the question). No navigational technology is perfect because no knowledge of everything between here and there can be perfect. Therefore, the ship arrives at the termination of each "jump" and must re-determine its location in space before plotting and executing the next jump.
If you're thinking this sounds a lot like space travel in Asimov's "Foundation" series... I've been re-reading it recently and it's definitely an influence on the question.
With each jump of approximately 80 million light years, the light from the star the ship is approaching gets "younger," meaning that it's traveled less distance, and it represents a star that's getting perceptually "older," meaning it's true age from day #1 of the universe vs. the very young age we see through a telescope from Earth.
Question: Since the age of the star in question is getting older as the ship gets nearer jump-by-jump, is the spectral description of the star stable enough or predictable enough to remain entirely identifiable and therefore useful for navigation? In short, can I find it and point my ship at it after each jump?
My goal is to choose how "local" a star chart must be based on today's understanding of solar physics. In short, can someone travel the entire distance without the need of a star chart other than the data acquired on Earth? Or must they pick up the local star chart at, worst case, each jump to have their destination re-identified?
I recognize that a second problem is that over that distance, the star is "moving," meaning where is is "today" when the ship launches from Earth is very different from where it is "then" when the ship arrives, eight billion years into the star's future as perceived by its light from Earth. I'm ignoring that right now because (in my world, if not in reality) the motion of stars is more predictable than the motion of a space ship. I recognize that if the answer is along the lines of, "finding that star at each jump would be whomping difficult," that it would means very-long-distance travel without the aid of localized/regionalized star charts from earlier (and much slower) exploration would be next to impossible as all of the stars's apparent ages and locations are changing substantially over that distance.
I also recognize that at that distance it's plausible that the star has gone nova or some such fairly inconvenient thing, which the travelers will discover as they jump. Or would they? As a bonus question, but one no one is obligated to answer, can the original star be detected in the nova remains for the purpose of navigation? We'll assume the travelers still want to get there. Hopefully they'll be in a hyperspatial jump when passing the advancing cloud of destruction.
