I was curious if you considered the possibility that the display zooms to some point on the other side of the core

I noticed that your website doesn't mention this.
On the page (which, you may have noticed, has "unfinished, up for reference" as a preface on the main page), all I say is "you can see that the zoom-in is toward the center of the galaxy". I don't make any distance claims there. On here, though, I have ventured rough estimates.
The zoom occurs so rapidly it is difficult to determine just where it is stopping. That is why I give a ~10,000 light year margin of error from dead center. However, given the angle at which we see the galaxy, there simply isn't going to be much in front of or behind the core area for us to look at except empty space.
