You're right, just about every one of those is off topic (ok, some may be borderline), and many of them are already closed. I don't really see much of an on-topic use for this tag anyway, so it really needs to go.

I've recreated the tag but if you want to keep it around for more than six months, find another question to add it to or give it a tag wiki. Or, if you decide that you don't want it, just remove it from the question and it will go away in 24 hours. This hinges on a prohibition in tag creation coupled with a synonym where the master is deleted. Long ago we ...

Voting on the question is currently +3/-0 and there's an affirmative comment with two upvotes as well. If there are no further objections, I'll go ahead and start adding the eyepiece tag to the estimated 50 questions where it's appropriate. As usual I'll do it in smaller groups so as not to overwhelm the active queue. I estimate that roughly 50 questions ...

It's been done, thanks! https://astronomy.stackexchange.com/tags/csst/info Questions regarding the CSST, aka the Chinese Space Station Telescope or Xuntian.

Manually retagging more than 4-5 questions in a big batch is discouraged because unfortunately it clutters the active questions feed. But if you want to slowly work them in over time, I don't see anything wrong with that. Since you use an abbreviation you should probably create a tag excerpt that describes the tag and spells out Hertzsprung-Russell diagram.

I was the OP of the question that uhoh mentioned in the question and I just used the "resource" tag to search for questions similar to mine. The presence of two similar tags of the same meaning is just misleading and may cause the creation of more duplicate and redundant questions. So, unless the two tags do have different meanings, is it possible ...

I think sky-survey is totally fine. Among astronomers, these are normally just called "surveys" because the "sky" part is implied by context and the background of the people having the discussion. For the more general audience of SE, putting the "sky-" prefix before it helps remove any ambiguity about what is being surveyed (and would be in good company of ...

Absorption by the atmosphere increases from 100GHz to 1Thz, which can be partially avoided by putting telescopes at high, dry places. But any line is going to be arbitrary. I don't see any real benefit in writing any particular number. "radio" should be synonymous with "radio astronomy" (I don't care which way the synonym works, but there are 13 [radio] ...

update: I checked and discovered that following this answer there's been an unmentioned edit to the two tags with frequency specifications, so I'm mentioning it now. Should we update definitions and remove the 100 GHz hard limits on radio astronomy related tags? Yes There are plenty of dishes that focus into waveguides or horns that feed antennas ...

The only problem with the tag as-is is that it doesn't appear when you search for "CCD" :-) Also, would a future "CMOS" tag be appropriate, or would an all-encompassing "imaging devices" or "photon sensors" tag be better?

+3/-0 votes on the question so far and no negative comments; it seems like the tag is okay.

Based on a quick Google search, they do appear to be completely synonymous. I think we should prefer habitable-zone as the main tag and make goldilocks-zone a synonym, because "habitable" is a more plain rendering of the concept whereas "goldilocks" requires an understanding of the British fairy tale and how the parallel is drawn ("...
