While Traveling the Galaxy in a Spacecraft, You and a Colleague

Essay

While traveling the galaxy in a spacecraft, you and a colleague set out to investigate a 10M _$\odot$ black hole. Your colleague hops aboard an escape pod and drops into a circular orbit around the black hole maintaining a distance of 50 km from it, while you remain much farther away inside the spacecraft. After doing some experiments to measure the strength of gravity, your colleague signals the results back to you using a green laser. What would you see, and why?
