The sentence "Then I can’t remember how I would locate Sagittarius each day" and also absence of any elaboration on how the galactic center is calculated.
I built up the intuition 10 years before the 2021 post -- it's a while back so my memory is fuzzy. But once you've got the ecliptic, you're most of the way there: you can visualise where the Earth is in its orbit based on the time of year, and Sgr A* is in a fixed direction relative to the Solar System.
Build up to it, a few minutes waiting for the bus every day, checking your sense with an app like Star Walk... it's relatively straightforward. I've learnt harder things I'm sure.

If you can't remember why even mention it ?
