Star Trek Mapping: Confirming a Binary?

I'm wondering about two stars, WT 767 and 768, both in Indus (I believe, after checking Gaia Sky), and it looks to me as if they're barely a light-year from each other. If I'm correct, they might be a candidate as "host" stars for Sullivan's Planet from "The Sehlat Who Ate Its Tail".

In which case, maybe HD 205156 can serve as "Helicon"?

I'm also asking my WT 767+768 question on the Celestia Discord server.

Due South Geography Questions

Does anyone in the fandom hereabouts remember the address of Fraser's first apartment building, as well as the general neighbourhood of same?

I'm thinking this is a thing that must be added to The Atlas of Imagined Cities, and it didn't get included in the Chicago section.
