ohhhh, this is good!

Using the 3.9m AAT, Sarah Caddy and Lee Spitler (from our school!) were able to track Orion on its return trajectory ...

... when the astronauts were still 200,000 km away from Earth! 🤯

That's at a distance of ~16 Earth diameters away, and Orion is a tiny tiny tiny spaceship at such great distances ....

But a big 3.9m telescope is also a handy toy to play with!
