Oh yeah, and if anyone so inclined wishes to add a distant Vader’s castle to the reverse shot when Kylo picks up and looks at the Wayfinder, I won’t try to stop you.
One can mask this landscape into the background of that shot:

Simple solution: Someone superimpose a sign that says
“Vader’s Castle 1.3 miles
Darth Cupcakes 2.1 miles”
Man, I’m a problem solver!
