If these "Einstein Crosses” are what these orthodox cosmologists claim they are, then it is amazing that we are so conveniently sitting right at the exact focal length for them to make such well focused images on 90° axes. I think that if they were such lenses there would be hundreds more which produce fuzzy, out-of-focus "Einstein Crosses" or even "Einstein Rings" where the light fails to come into focus. We don’t see that. . . Nor do we see light bent around in a single image matching another we see in the other side. We should.
Here’s are some examples of Einstein Rings...

And you are right. The alignment, as well as the focus,
needs to be right for us to see it. If we were in another
galaxy, we likely wouldn’t have seen this one, yet other
alignments could present themselves.
On occasion.
Now, if we could happen upon TWO such galactic gravity
lenses, with the right separation between them, and in
alignment and focus with us, then we might get to
see Four identical little Einstein Rings around an
Einstein Cross.
And see very, very far away indeed.
