So it's really difficult to keep your telescope pointingin the same direction. Instead, you actually reference the position of the star relative to things that are effectively infinitely far away, like very distant galaxies. And in that way, we calculate distance to the large megellanic cloud. You can go to these great distances, but only if you step on the powerlax rung before thad. It goes further out until you're using red shift and calevraasurers for example. To calibrate red shift, she've got all these
