Hubble question

If you look sideways out of your moving car at a distant building, you dont
have to move your head as the object stays in the same direction. The
further away it is the longer it seems to stay in the same place. Hubble is
looking at objects millions of miles away so will appear in the same point
of space even though Hubblle is moving around 8000 miles in either
direction.

Ah, but the curve isn't going around a bend.

If it is, you have to turn your head.

Hubble is very good at this, but does have limiting factors such as making
sure it doesn't point at the Earth or the Moon while doing this. So if the
object is in-plane, it has to "look-away" during part of every orbit.

If it's looking above or below the poles, I believe it can continue to look
the entiretime.
