Where is the best place to find relays? I’ve seen mentions of relays existing by topic, however I’ve been unable to find this level of detail.
I see https://nostr.watch/ and have searched for a list with more details, without success so far.
I’d like to be able to find relays that specialize in astronomy, photography, sports, and other topics…does this exist?
You're still early to the party. There's been a lot of discussion about topical relays recently. Given enough time, they will become more prevalent. Given enough desire, one could start one.
Another relay explorer is nostrrr.com if you want to poke around there.
