Just to illustrate what I mean above, I am over 1bn km above Kerbol on the way to Polaris.
Looking down, Kerbol looks like this: https://imgur.com/i9rNsoN
And looking up, Polaris looks like this: https://imgur.com/nEuyket
Kerbol has almost faded away, it's just a bright star at this point, whereas Polaris always looks the same, it's pretty much as bright as Kerbol from Kerbin.
