Earth-centered view in ICRF frame

There should be a way to get a view similar to the Home view, centered on the Earth, in the ICRF frame instead of Earth-fixed.

Start by locating the implementation of the Home view and the code that handles Earth-fixed and ICRF frames. Trace how the view is centered and oriented, then determine the expected Earth-centered ICRF behavior. Done means a view comparable to Home is centered on Earth while using the ICRF frame.
