I think the MOG window can be allowed, since it showed Kirk what he expected to see (i.e. stars, at least at first). This (in my mind, anyway) is backed up by the windows in COK, through which blatant stars are seen.
BTW, I do like that Carrara shot. Since we never saw the ceiling at such, there's no reaosn to disallow it at all either, and it makes a nice bridge (if you'll pardon the pun) between TOS and TMP
