For pedantry's sake: neither i.e. nor e.g. would be correct here. You want cf. ("conferatur") to invite a comparison; e.g. is when an example pertains to an instance. In this case uv would not pertain to the instance, because Astro is not Astral.
(For the OP: I'm sorry if I misinterpreted you.)
Regardless, these Latin abbreviations best avoided entirely due to the surprising number of readers who don't understand them.
e.g. is latin for "exempli gratia" = for example i.e. is latin for "id est" = that is
e.g. - example given
i.e. - in effect
It's possible you are right, but it isn't clear from the content of the comment.
