Did you do every single thing you have to do, in order to unlock being able to do that one sightseeing point you want?

Unlock the sightseeing log itself, get the ARR log, take it to the person who has the HW log, get the HW log clues...

And THEN stand in the right place, doing the right action in the right time and weather?

Given that this is a HW sightseeing, the question comes down to, "show me a picture of the spot with the glowing orb".
