When Chrisjen Avasarala is in Frank Degraaf's office, there is a large telescope by the window. It is a Newtonian reflector on an equatorial mount, but the telescope is pointing to the floor instead of the sky. The eyepiece and finder scope are at the rear end of the telescope which would be correct for a refractor scope, but not for this type of telescope. There appears to be a cover over the normally open end of the telescope (to protect the optics) which may have confused the set decorator.
