In Interstellar would the ship appear to be heading towards Miller's Planet for years or does time only begin to slow down once they have begun their descent into the planet's atmosphere?

Since they spend 23 earth years on Miller's Planet what would it look like to Romilly who was still on The Endurance? Would he still see the ship in space heading towards the planet for years or would he not be able to see them?

So, the orbital mechanics of Interstellar don't *entirely* make sense. But yeah, if a spaceship moves very close to a black hole, an external observer would see them as moving much more slowly. The light would be emitted more slowly too, which would make them very dim. This would also make the frequency of the light go down too. So as a spaceship approaches the event horizon, a distant observer would see them moving slower and slower, getting dimmer and dimmer, and redder and redder.
